Look at the walk-behind tractor, a homemade trailer with steering wheels. Do-it-yourself homemade trailers for a walk-behind tractor, video. Self-assembly of a walk-behind trailer - it couldn’t be easier
Owners of personal plots and gardeners often use a walk-behind tractor. It can be seen in almost every subsidiary farm. Technology is indispensable and necessary to get the job done. various kinds. In addition to soil cultivation, a mechanized device can be used to transport cargo (hay, fertilizers, planting materials, firewood and garbage). If you purchase a walk-behind tractor or a snowmobile without a trailer, you shouldn’t be upset, because you can make a trailer hitch for the walk-behind tractor with your own hands.
The configuration of the walk-behind tractor can be very diverse:
- Hiller.
- Grunt
- Plow.
- Potato planter.
- Seeder.
- Rake.
- Mower.
This is characterized by the equipment’s carrying capacity, weight, power and other indicators. The walk-behind tractor can be medium, light and heavy (professional). A motor cultivator is considered an analogue of this technique, but it is made to perform one job - cultivating the land. Sometimes it may come with an additional feature.
The design of the carts is not complicated. In the presence of ordinary tools Almost any owner can independently build a cart for a motor cultivator or Neva walk-behind tractor. An important part of manufacturing is correct composition drawing or sketch. The main work should begin, strictly adhering to the intended dimensions. To simplify the process, you can take the factory model of the cart as a sample. Trailers can be of large and small load capacity (500 or 100 kg). At the same time, the body differs in size.
For different types walk-behind tractors are selected by trolleys with different technical characteristics:
- For heavy ones (more than 10 hp), a single-axle or two-axle cart with a body length of up to 1.5 m in width and 3 m in length can be used.
- For medium-sized ones (power up to 10 hp), single-axle trolleys with a body length of up to 1.5 m and a width of up to 1.4 m are most often used. The load capacity of such trolleys is approximately 300-500 kg.
- For light trailers (power up to 4.8 hp), single-axle trailers with a body length of about 1.15 m and a width of 1 m are used. The trolleys are designed for a load of up to 300 kg.
The sides in carts can be up to 40 cm high, and with side guards in powerful trailers - up to 60 cm. To facilitate the process of unloading or loading, the design provides an opening or removable tailgate. Models with removable side walls can also be produced.
Standard models of towbars are characterized by placing the center of gravity at the rear, which makes it easier to tip the cart and unload some cargo. Only heavy-duty models are usually equipped with a hydraulic lift cylinder. Such models must be equipped with brakes, since on steep slopes the inertial force of movement will act and it will not be possible to stop the walk-behind tractor.
Pros and cons of a homemade trailer
There are many ready-made structures, which are offered by tractor manufacturers and third-party manufacturers. Thanks to the cart, the walk-behind tractor will be a full-fledged transport, but to decide between a purchased and homemade model, their merits need to be reconsidered: 
- An indispensable device for working in the country.
- For manufacturing, you can use simple material and technology.
- During production, money is significantly saved.
When purchasing, it is not always possible to find a unit that is suitable for all characteristics, and its quality and technical specifications may be much lower than the price.
Proper design
To prevent repeated reworking of parts during the assembly process, as well as to save material that could be damaged, you need to create a detailed and careful drawing. It is best to create multiple drawings of each part from all sides. This is especially true for complex parts.
When making a drawing and preparing sketches, you can miss important nuances. In this regard, the drawing need to be reviewed and studied taking into account the following points:
- Determine which main or auxiliary unit the trailer needs, and also find out the connection method. It can be carried out in different ways (welding, bolts or rivets).
- Movement and connection of stationary rotating parts (on hinges, bushings, bearings or in an axial manner).
- Are parking mechanisms necessary?
- The presence of a body tipper.
At the same time, there are many other elements that need to be taken into account and created depending on your own needs and desires. For example, not everyone will agree to make a swivel joint with their own hands, but many will be able to buy it cheaply from scrap metal. In the drawings, if necessary, clarifications and detailed drawings are made. Creating a drawing is not an easy process, but after that it is possible to complete and correctly list the necessary spare parts and tools.
Before purchasing materials and creating drawings, you need to examine the available parts, since any metal products may be useful for creating a structure or additional elements.
Development of a lightweight trolley
A dolly with a load capacity of up to 350 kg is suitable for any type of walk-behind tractor, and a dolly with a higher load capacity will require the development of additional brakes, since it will be unsafe to use (it can be used as a tow truck). To make a lightweight trailer with your own hands, size drawings can be easily found on the Internet. They need to be modified to suit your needs, depending on the availability of blanks and requirements.
The load capacity will depend on the choice of dimensions and dimensions of the body itself. To do this, you can use manufacturers' dimensions, and develop a drawing It is recommended to carry out this step by step:
- General view with dimensions of all components, such as body, frame, wheels and carrier.
- Detail view of a frame made from square or round pipe and connected by welding.
- Body and its structure. The body can be made of boards or metal.
- It is advisable to reinforce the carrier with several stiffening ribs, since the main load will be placed on it through the swivel unit and the drawbar.
- Swivel unit - complex element, requiring special attention.
Depending on the choice of material for the manufacture and strengthening of certain sections of the structure, the use of a walk-behind tractor trolley can be subject to different loads.
Manufacturing details and materials
To make a tow hitch you will need:
After preparation necessary details and tools, you can start working, but it is very important to clean the metal from rust before work using a grinder and a converter.
Trailer frame
The best option for creating a frame would be cut round and square pipes, as well as corners. The design is suitable for use on uneven roads. The frame can be made using bearings and some pipes. You also need to install the wheels. A steel rod with a diameter of 30 mm and a length of 1080 mm is suitable for creating an axle on which the wheels will be mounted. Such a rod is welded to the hinge and frame posts.
Motoblock trolley carrier
The structure is created from parts that are reliably welded. The main load is created on the rotary and coupling mechanisms, so the structure needs to be strengthened metal parts welding method. To make the carrier, you need to weld the support corners, gussets with longitudinal hinges and body bars.
Homemade device body
The body for a homemade wheelbarrow can be made from suitable metal or a board with a cross-section of 20 mm. When making from boards, it is necessary to strengthen the structure metal corners. The body must be connected to the frame at several points using supporting parts. The center of gravity in a single-axle cart should not cross the wheel axle.
When creating a dump body structure, you need to install axles for the folding device in the middle of the frame. In this case, it is important to install them coaxially and accurately orientate them, since when incorrect installation Lifting the body may be difficult due to jamming. The axle bushings are welded through a reinforcing plate about 5 mm thick. The coupling device, which is the basis of the frame, is also equipped with such amplifiers. Conventional hinges, often used in the construction of hinged gates and gates, can be used as bushings and axles, but with a diameter that will allow them to withstand the weight of the load. After finishing welding, you need to check the free movement. This design is not dismountable, so to prevent recycling, the axles must be installed the first time.
Connecting a walk-behind tractor with a trolley
To connect the trailer to the tractor, you need to make a console. Top part the support may be similar to the contour of the cultivator handles, since it needs to be attached to the console mounted type. At the attachment point between the bearings, apply grease and cover with a boot. If there is a large load on the trailer during operation, it is recommended to manufacture a movable hitch. The connecting mount of the device is installed in the cylindrical body of the longitudinal hinge and the entire structure is locked with a ring.
To make a coupling device you will need:
With this design, it is easier to control the walk-behind tractor on uneven road surfaces.
Choosing trailer wheels
Many craftsmen who make towbars leave reviews on websites that recommend installing motorcycle tires together with a central part kit. However, in this case it is necessary to grind the axle rod to match the dimensions with the diameters of the hub bearings.
A circle with a diameter of 3 cm is perfect for turning and creating a central wheel base. The central shaft, longitudinal hinges and corner supports are connected by welding. If you select other wheel pair options you can perform the following operations:
- Attach the angle to the transverse part of the frame or weld a piece of pipe.
- Drill a hole in the bottom of the angle or pipe to fix the fitting and the wheel axle.
Working with the bottom of a trailer
To make a strong bottom it is best to use metal sheets thickness from 2 to 3 mm. You can also use edged board, but the bottom will be less durable.
At the final stage, be sure to secure the driver's seat and check the installation of the wheels. For greater convenience, it is necessary to weld the footrest so that the legs do not remain in the air. For improvement appearance The trailer can be cleaned and painted.
The assembly of the structure must be carried out on a flat surface. When choosing a profile of approximately 40-50 mm, you will not need to reinforce the structure with gussets. With normal and uniform welding seams, the structure will be quite rigid, so if you do not have welding skills, it is better to hire an experienced person. After painting the device with special paint, all parts will be protected from corrosion, and the cart will last longer. While creating folding design it is necessary to weld the lock and use a steel pin with a cotter pin.
Many farmers are interested in how to make a trailer for a walk-behind tractor with their own hands. Additional accessories to the walk-behind tractor, such as a trailer, expand the capabilities of the equipment. The process of transporting firewood, hay, livestock feed, and any other cargo is simplified.
What is a trailer for a walk-behind tractor?
The towbar to the walk-behind tractor consists of:
- body;
- wheels;
- wings;
- seats;
- drawbar;
- brakes
The ability of the body to withstand a particular load depends on the quality of the assembly. The cart must be made of durable material that can withstand the weight of the load and any weather conditions. In addition, it is desirable that it have folding sides for ease of loading and unloading. The dimensions must be roomy and match the power of the walk-behind tractor.
Wheels are used on carts: car wheels, motorcycle wheels, etc. The main thing is that they can withstand heavy loads.
Wide wheels are preferable, as this increases the vehicle's maneuverability.
There are wings on cars too. Serve as protection against stones and dirt from wheels.
All modern trailers are equipped with seats. Some craftsmen build a box underneath to store necessary things.
The drawbar is a triangle-shaped mount that connects the trailer to the walk-behind tractor.
Brakes will improve the process of transporting goods.
Trailed equipment for walk-behind tractors can be purchased from manufacturers of agricultural machinery, or you can make a homemade trailer for a walk-behind tractor. Let's consider both options.
There are many on the market ready-made models for motor cultivators. They have different sizes, weight category, carrying capacity and cost. Their advantage is that they are assembled by professional mechanics according to pre-developed schemes. You don’t waste any effort or time on this. The disadvantages are, firstly, the search for a conscientious manufacturer that sells a quality product, and secondly, a high-quality product is not cheap.
The walk-behind tractor acts as a horse cart. It acts as a drive connected by a drawbar to the trailer. The following brands of walk-behind tractors are suitable for this purpose: Patriot, Ural, Cayman 320, Forza, Crosser, Foreman, Viking, Texas.
You can make a trailer for the Neva walk-behind tractor, made of durable metal. Load capacity of the body is 500 kg. The trolley has a brake drive, which makes driving easier. On the Internet you can find a lot of drawings of trailers for the Neva walk-behind tractor. They have good design with minimal consumables.
The walk-behind tractor is very convenient device for work in small and medium-sized farms. It is especially convenient if there are a lot of useful devices. One of these is a trailer. Indeed, due to such an addition to the walk-behind tractor, its capabilities and efficiency increase. As a result, the number of jobs that will be done manually is immediately reduced.
First of all, a walk-behind tractor is necessary for cultivating land plots. However, the trailer and others additional devices can make it even more practical. And the most simple model It's easy to do and you can assemble it yourself. This device is suitable for any household.
Blueprints
Before you start building a trailer, you should carefully consider its purpose. The size of the device largely depends on this. In this case, the parameters of the trailer must match the specific walk-behind tractor to make it convenient to use them together. According to the power of walk-behind tractors, they are distinguished the following types trailers:
Motoblocks with power up to 5 liters. With. fits well with trailers on one axle. The body of such devices has maximum dimensions 1 by 1.15 meters and is considered light. Medium trailers are suitable for walk-behind tractors with a capacity of 5 to 10 hp. With. The dimensions of such devices can be 1 by 1.5 meters or 1.1 by 1.4 meters. They are designed to transport cargo weighing from 300 to 500 kg.
For cultivators with a power of 10 HP. With. It is best to use a body with two axles. Its dimensions will be approximately 1.2 by 2 meters. In such a trailer it will be possible to transport cargo weighing up to 1 ton. These are the ones that are considered heavy.
When the dimensions of the trailer are known, drawings or sketches of the device should be made. The best option, if the structure is depicted from different angles. It is also important to mark the sketches with dimensions and carefully show all existing nodes.
A simple trailer consists of the following basic components:
carrier, consisting of several parts;
durable frame;
convenient body with frame;
wheels of the correct size.
The carrier includes such parts as a housing for the unit responsible for turning, a pipe drawbar, a footrest frame, a pipe stop, ribs for rigidity, and overhead parts in the form of strips. The parts are usually connected using welding machine. The greatest load falls on the place where the drawbar connects to the swivel unit. It is this that needs to be well reinforced using stiffening ribs.
The frame is most often made of steel, or, more precisely, rods (pipes), the diameter of which is at least 3 cm. Connections on the frame are made using welding, gussets, side members, supports at the corners, and a longitudinal hinge body. Each frame must include a number of features depending on the terrain where it will be used: for example, holes, humps and much more.
The body can be made of both metal and wood. It can be solid or made of twigs.
When assembling it, it is worth considering for what purposes the trailer is needed and what kind of cargo will most often be transported in it.
In order to make a wheel axle, you should use a steel rod. Its diameter should be approximately 3 cm, and its length should be about 1.07 m. These parameters are best suited and do not allow the wheels to protrude beyond the trailer body. As for the wheels, they are suitable for almost any vehicle. The main thing is that they fit the design in size.
When preparing, it is necessary to take into account that the scheme includes a number of subtleties. An important point is the presence of not only main, but also auxiliary nodes. It is also important to choose in advance the method by which the knots will be fastened.
Moreover, it must be taken into account that some connections must be special, since they are responsible for the rotation. It is equally important to consider whether the trailer will be equipped with parking supports and a tipper for quick unloading.
Materials and tools
To create a trailer on a walk-behind tractor with your own hands, you may need the following tools:
spanners;
hammer or sledgehammer;
ruler or measuring tape;
screwdriver;
sandpaper;
file;
electric saw.
welder;
"Bulgarian";
lathe;
Depending on what materials will be used for the future trailer, the set of tools may vary slightly. However, most of them are indispensable when creating additional equipment for walk-behind tractor.
First of all, when choosing materials, it is worth considering what the trailer body will be made of. The cheapest material for it is wood. For example, you can use boards about 0.2 cm thick. It is worth considering that they need to be reinforced at the corners with metal overlays. It is convenient to fasten such a body using support frames made of timber and bolts.
Wooden trailers are best suited for transporting bagged goods. In this case, the sides of such a device will not fold down. It is advisable, before finally choosing what the body will be made of, to calculate the load, and also estimate what kind of cargo will be transported in it.
You can also make a body from metal sheets, the thickness of which is from 1 mm. This material is the most versatile. It is also quite easy to make it durable with the help of primer and painting.
Corrugated sheeting is also suitable for making a trailer. However, it must be taken into account that this material requires additional stiffening ribs.
To make a wheel axle, you can use a steel rod approximately one meter long. This length will allow you to place the wheels on your homemade trailer most correctly. A VAZ-2109 beam is also suitable as an axis. A good option would be to use the entire rear axle, including the wheels.
Wheels from any equipment can be used as wheels. The only condition is that their size matches the technology. Eg, good option for the trailer are wheels from a cradle or Zhiguli. You can also use wheels from garden equipment with a radius of 40.6-45.7 cm. Wheels from the Ant scooter would be a good option.
How to make a dump truck?
Tipper trailer for diesel walk-behind tractor will become an indispensable assistant on any farm. It is very convenient to transport cargo that can be easily unloaded in a matter of seconds. It is absolutely easy to make such a design with your own hands.
Moreover, a homemade trailer can be even better, since it will be made in accordance with all the necessary requirements.
It is best to start making a trailer from the body, or more precisely, from its frame. The side sides can be welded from profile pipes. The entire frame is made from similar pipes. You can check the connections for squareness using a regular construction square.
It is worth noting that when welding, you first need to “grab” it slightly. When it is clear that everything is assembled correctly, it will be possible to weld more firmly. It is very good if the welds are ground using a grinder.
It is best to make the tailgate removable to make it even easier to unload cargo. To attach it, ordinary door hinges, and for closing - bolts
To make the trailer safe at night, you can stick reflective stickers on the tailgate.
On the front board, as well as the side ones, it is necessary to weld small pieces of pipe, which will become racks for wooden or metal sides. The final stage- covering the frame with the selected material (wood or metal).
After this, you can make a drawbar from profile pipes. They must be firmly welded to the beam. The result will be a triangle-shaped structure. The structure should be strengthened in the corners using metal gussets, the thickness of which will be at least 4 mm. It is necessary to weld a metal plate with a thickness of more than 8 mm under the towbar in front.
To make the trailer a dump trailer, teardrop-shaped door hinges, which can be purchased at the store, should be welded to the beam, as well as to the bottom struts.
To secure the body, you can use a regular door latch. It is attached by welding to the spacer, which is located between the pipes that make up the drawbar. You can also purchase a one-piece self-tipping unit.
The latch should be inserted into a piece of pipe and welded. This ensures a strong connection. Opening occurs via a lever that can be attached to the seat. You can connect it to the latch using regular wire.
All that remains is to attach the wheels and axle. Practice has shown that it is best to take a ready-made axial structure right away. Depending on the load capacity and size, you can make a two- or four-wheel trailer.
Stability is important for every trailer; to achieve this, you can install a step in front of the front beam. It will allow the body to remain in a stable position even without a walk-behind tractor.
How can you make a two-axle trailer?
Single axle trailers are more common, but they have some disadvantages. In particular, this is their center of gravity. After all, if the position of the body is incorrect, the load will fall over. It can also lead to increased stress on the clutch, which will eventually ruin it. This can be avoided by placing the center of gravity strictly above the axis.
This drawback can be eliminated and the load capacity can be increased by using two-axle trailers. They consist of main blocks and assemblies, just like single-axis models. Their only difference is four wheels and two axles. Moreover, the axles are manufactured in the same way as in trailers with one axle.
This single-axle mini-tractor (one of the common names for a walk-behind tractor) is more versatile than its “relative”, the cultivator. But the scope of application of the walk-behind tractor can be further expanded by equipping it with a trailer. In this case, the functionality of the unit is not limited to mechanized cultivation of the land plot.
It becomes possible to organize transportation around the site and surrounding area of tools, soil, garbage, and so on, that is, everything that every owner faces with the need to move. It’s easy to make a small trailer for a walk-behind tractor with your own hands if you follow certain instructions and focus on standard drawings, dimensions and recommendations of professionals. This article will tell you how to do it correctly and what to consider.
The design of the trailer is developed based on the modification of the walk-behind tractor. These mechanisms are classified into classes depending on engine power. But even the weakest unit is capable of transporting up to 400 kg of cargo. For summer cottage plot or small homestead farming this is usually quite enough.
In principle, you can buy a trailer. But the minimum cost of a simple cart with sides is 18,400 rubles. And it’s not a fact that the dimensions design features products will satisfy the user. Making a homemade trailer on your own is not difficult. And if you consider that you can independently develop its individual drawing to suit your own needs, the feasibility of such a solution is obvious.
Trailer design features
Some points need to be thought through in advance, even before drawing up the drawing. What questions should you pay attention to?
- Connection methods. This applies to individual units and moving elements (bushings, axles and a number of others). What to choose - fixation with bolts, rivets or welding - is decided in advance.
- What to make trailer parking supports (legs) from.
- Seat option - rotating or stationary. The first one is more convenient, the second one is easier to make with your own hands.
- Body modification. In terms of universal operation of the walk-behind tractor, a tilting design is preferable, but its manufacture is much more complicated. And such a trailer will cost much more.
- A type of connecting unit (trailer - walk-behind tractor). It can be hinged, on bushings, bearings. The same is something to think about.
Without taking these nuances into account, it is pointless to start developing a project and drawing up a drawing. You should also take into account such aspects as your own capabilities, the availability of the necessary materials (parts) and personal experience in assembling something on your own (practical skills).
Features of the design of the trailer for the walk-behind tractor
Even to make it yourself, you will have to choose from several options.
But if you understand what main parts a trailer consists of, then draw up a drawing of it, decide on the dimensions of the “cart” and select necessary materials simple enough. Yes and any step by step instructions not needed - the master himself, depending on the conditions, chooses the sequence of technological operations and the method of their implementation.
All dimensions indicated, unless otherwise stated, are in mm.
Trailer frame and body
In fact, this is the base that supports part of the entire structure. Therefore, only metal is suitable for the trailer frame. Using wood blanks to assemble the frame of a homemade cart (which is sometimes practiced by “home” craftsmen with little experience) is impractical for several reasons.
Firstly, any tree contains a certain percentage of moisture. Consequently, material shrinkage, twisting, and the like cannot be avoided. As a result, the trailer will be repaired more than it will be used.
Secondly, wood has many “sworn” friends - ultraviolet radiation, dampness, wood-boring insects. Such a trailer for a walk-behind tractor will not last long.
Thirdly, the insufficient bending strength of wood limits the load-carrying capabilities of the cart.
Consequently, in this case, saving on materials is more than impractical. The easiest way is to mount a frame from profiled pipes. In terms of ease of assembly for the trailer, it is advisable to use blanks with a rectangular or square cross-section. They are stiffer and less susceptible to deformation when the trailer is overloaded. In addition, you can most connections (if not all) should be made without a welding machine, using bolts; The process of covering the trailer frame with the selected material, be it sheet iron, corrugated sheets or boards, will also be significantly simplified.
The drawbar is easy to make from the same pipes and channels. For ease of use, it can be composed. For example, from sections of 2 pipes (channels) different diameters(numbers). Actually, your imagination itself will tell you exactly how to make everything.
For a small trailer to a walk-behind tractor, they are enough following parameters: 50 (60) x 30 for the frame and 25 x 25 for the racks. As an option - a small profile channel (for example, No. 5). A 15-gauge board or 1.5-gauge sheet iron (duralumin) is suitable for lining the sides. For the bottom, the metal should be thicker, at least 2, otherwise deflections cannot be avoided. To give the trailer strength, after assembling the entire frame, it is necessary to make the upper frame of the racks. Suitable for these purposes. Depending on the size of the trolley - 15 or 25.
Pair of wheels
To secure the axle, you will have to install special supports at the bottom of the frame. They are welded to it (in the form of scarves), so in this case bolted connection unacceptable. The photo explains how everything can be arranged (option).
The axle is taken either ready-made, from used equipment, or used metal rod. Minimum diameter– 30. The dimensions of all elements are selected based on what wheels the trailer will be equipped with. For a do-it-yourself walk-behind tractor, both “Zhigulevskie” ones (the rear beam from a “nine” is often used) and a simple garden cart are suitable. By the way, it can be used as a basis when designing a trailer. Only a small modification of the circuit is needed.
Hitch
When developing its design, you need to take into account the features of this walk-behind tractor unit. Models different manufacturers- their differences. Here are some acceptable DIY options.
Since the mobility of the connection is ensured by bearings, they must be protected from the ingress of foreign fractions. Therefore, you should think about how to correctly execute the anthers.
In principle, a skilled person is more detailed instructions and not needed. Having grasped the essence, it is easy to create your own version of a trailer for a walk-behind tractor, develop its drawing and assemble the cart with your own hands.
Walk-behind tractor - useful thing for those who have a large plot of land. But this technique can be used not only for plowing, harrowing and other field work. If you attach a trolley to the walk-behind tractor, it can be used as a cargo vehicle. It’s easy to make a spacious wheelbarrow with your own hands. A trailer for a walk-behind tractor allows you to transport hay, bags of grain, vegetables and other cargo.
Restrictions on use
The safety issues of a driver driving a walk-behind tractor with a cart have not been worked out, so it is not possible to drive such a cargo vehicle everywhere. The traffic police does not allow driving on the roads common use, although in rural areas sanctions are unlikely to be applied to the violator. However, it is better to be careful and not break the rules. You can safely drive equipment with a trailer in the following places:
- along the road laid between the field and the forest belt;
- In the woods;
- on a dirt road passing through a meadow, steppe, etc.
You are also allowed to move within your area and in the vicinity of the village (where there is no roadway). The main thing is that there is no risk of an accident. Trailer structures are sold in finished form Therefore, there is no explicit ban on their use. IN winter time The wheelbarrow can be attached to a snowmobile to transport firewood or animal feed.
Materials and tools
Before making a towbar for a Neva walk-behind tractor or another brand with your own hands, you need to clearly imagine what the end result will be. It can be helpful to visit a store that sells factory trailers and see how they are built. Walk-behind tractor with cart - stable vehicle, since it rests on 3 or 5 wheels. A trailer can carry an impressive amount of weight, but exactly how much depends on the characteristics of the model (you need to read the instructions). Here's what you'll need to make your own trailer:
There is a simpler option - a rolling dump truck, similar to a tow truck. It can also transport cargo. The elements that make up a homemade rolling device: two wheels, two pipes and a detachable drawbar. The device is convenient because it does not take up much space when stored.
Main parts of the cart
The typical design of a trolley for a motor cultivator consists of a certain set of elements, but it is easy to modify it to suit your needs. For example, the owner of a walk-behind tractor may decide that additional components are needed. The main details will be:
The cart rests on two or four wheels. Accordingly, it turns out to be biaxial or quadriaxial. What to choose, the owner of the walk-behind tractor decides for himself. The version with four wheels is more stable, but it is more difficult to manufacture. In addition, a two-axle cart weighs more than a two-wheeled cart. It is recommended to focus on the power of the walk-behind tractor.
If the power of the equipment does not exceed 5 hp. With., optimal sizes the length and width of the trailer will be 1.5 and 1 m. When the parameters of the body are calculated, pieces of the required length are cut from the corrugated pipe and the frame is welded from them. The design is quite rigid, so there is no need to install reinforcing elements in the corners. In order for the seam to be smooth and of high quality along its entire length, you should work on a flat surface, preferably using electric arc welding.
Body assembly and painting
The sides of the trailer are framed with a 25-30 mm profile. Sheathing is assembled from sheet metal, which is then attached to the corrugated pipe. threaded connections. The metal for the body must be free of rust. If there is corrosion, it is removed mechanically, and then cover the surface with a priming rust converter. The body is fitted to the frame. If all dimensions match, perform test build. Then they disassemble, set the body aside, and cover the frame oil paint. It is necessary that there are no unpainted elements left anywhere.
Helpful advice : If possible, it is better to use a polymer-based dye. The primer should not be neglected in this case either, because adhesion is better on the treated surface. Powder dyes are more resistant to abrasion, and surfaces coated with conventional oil compositions, need to be updated at the beginning and end of the season.
The body flooring is also coated with paint, after which it is installed in its place. Fix the joints with fasteners, then paint the protruding parts of the bolts so that corrosion does not appear in these places. If the dried paint has come off in some places during installation, these areas are touched up. A drawbar is made from the thickest pipe.
Steering gear
Since the design includes a tilting trolley, special axles are made from the bottom in the middle. To prevent the folding mechanism from jamming when lifting, it is necessary to maintain alignment. Reinforcement bushings are attached using a plate 5-6 mm thick. The same parts are welded to the coupling device (drawbar), which serves as the base frame.
Assembling a hinge joint with your own hands requires increased precision. The basis is a circle of of stainless steel with a diameter of 5 cm. The studs are also machined from steel, only hardened. Since the intensity of movement of the hinge will be low, you can do without bearings, the main thing is to regularly lubricate the mechanism.
The steering structure is fixed to the coupling device. The horizontal hinge is made removable, the bushing from it is bolted to the drawbar. The steering joint is located vertically on the tow pin.
When everything is ready, perform a test loading and check if there are any problems during movement, during turns, when starting, stopping, etc. If the equipment with a trailer works normally in all modes, the structure is ready for operation. If the power of the walk-behind tractor allows, the cart can be loaded with 300 to 700 kg.
A homemade trailer is several times cheaper than a factory one., and it will serve for decades. The main thing is to use quality materials, observe the dimensions and assemble carefully.
