Do-it-yourself dump trailer for a walk-behind tractor. Homemade dump trailer for walk-behind tractor salute How to make a seat for a walk-behind tractor trailer

The walk-behind tractor is a universal unit, which is composed of additional equipment capable of performing any work in agriculture. This includes plowing a field, cultivating and loosening the soil, but many also dream of making a transporter out of a walk-behind tractor.

But, given the fairly high cost of the trailer, there is no longer enough money to purchase additional equipment, so many farmers resort to designing it themselves. In this article we will look at detailed instructions for making a trailer for a walk-behind tractor with your own hands. But first of all, let's get acquainted with the types of hand tractors.

Types of walk-behind tractors

Before you begin to consider the instructions for making a trailer, the first step is to determine its carrying capacity. Factory devices are capable of transporting loads weighing from 300 to 1000 kg, but, of course, this depends on the characteristics of the tractor itself.

Depending on power and performance, all hand tractors can be divided into:

• lungs
• average
• heavy.

Depending on the type of tractor, the dimensions of the trailer are selected. For the lungs the best option the body will be no wider than 1 m and no longer than 1.15 m. It is in this volume that you can fit up to 300 kg of weight.

For medium-sized units, the body length can reach 1.5 m, where up to 500 kg can be loaded. And the dimensions of the trailer for heavy walk-behind tractors can reach 3 m in length with the same 1 or 1.2 m in width.

Types of trailers depending on the device

Trailers for walk-behind tractors, depending on the specifics of the work, can be:

• with a folding body;
• with stationary;
• with folding rear or folding side walls;
• the folding mechanism can be mechanical or hydraulic;
• with a hand brake (usually a self-moving device is used on trailers for heavy tractors).

When developing the design of a trailer for a walk-behind tractor, it is imperative to take into account its center of gravity. It should be shifted forward relative to the axis closer to the front side. This will not only increase the stability of the transporter, but also ensure optimal controllability during movement.

Trailer design for walk-behind tractors

Having decided on the carrying capacity and power of a hand tractor, you can begin to design trailers. First, let's look at the design of a simple trolley without a folding body. At first glance at a trailer in a branded factory design, it will seem that its design is complex.

But in reality this is not the case, because it includes the simplest parts that are attached to each other in the most ordinary way (bolted and welded connections). The device does not contain complex components that need to be manufactured using sophisticated equipment. So, what elements does a walk-behind tractor trailer consist of?

1. Clutch device for walk-behind tractor.

2. Articulated rotary device (console).

3. Driven.

4. Step.

5. Driver's seat.

6. Frame.

7. Body.

8. Support beam.

9. Hinge lock.

10. Rear hinge device.

11. Axle with wheels.

We looked at the design of a trailer without a hand brake. If it is necessary to provide a spontaneous movement blocker, then the wheels and calipers can be taken from the rear axle of a small car. They already have a drum-type manual locking mechanism.

The figure presented earlier shows all the recommended trailer sizes for a manual tractor of average power, about 5 hp. The body material can be not only boards, but also plywood, rolled sheets, and profiled metal sheets.

It is also clear from the device that the carrier is fixed to the central pipe by inserting it inside and through. Its second end at the rear is hinged, which allows the trailer wheels to change their position relative to the plane of the tractor axis without creating inconvenience when overcoming holes and potholes. The “pipe-in-pipe” technology provides the required stability during the straight-line movement of the walk-behind tractor, without distorting the frame, thereby not creating emergency situations.

Carrier device

Now let's take a closer look at the design of the carrier. It, as can be seen from the drawing, does not have many details:

1. Rotary mechanism.
2. Drawbar.
3. Step.
4. Stiffening ribs on the hinge.

The coupling of the walk-behind tractor with the trailer is carried out through a hinge joint, which consists of a steel axle, bearings and a flange. A hand tractor is attached to the latter using a bolted connection.

An important factor in the quality connection of the walk-behind tractor and the trailer is a well-designed hinge. Therefore, it is recommended to use at least 4 stiffeners made of steel strip with a thickness of at least 4 mm.

Trailer frame design

From the diagram below you can see that the frame structurally includes different kinds profile and round pipes welded together. The thickness of the profile is selected based on the required load capacity of the trailer.

What do we see in the drawing?

1. A brace that strengthens the structure of the seats.
2. Driver's seat frame.
3. Seat support or post.
4, 5, 9, 10. Front and rear struts.
6. Frame or outer frame of the platform.
11. Reinforcing cross member.
12. Central axis.
13. An axle made of a rod with a diameter of 30 mm.
14. A scarf made of rolled sheets 4 mm thick.

If you are interested in how to do screw splitter with your own hands, then you can read more about this in.

The frame also provides a seat mount, which can be folding or stationary. Depending on this, the type of design of the folding device is selected.

Method of fastening the carrier and central pipe

Bolts and studs are used to secure the carrier. A hole for the fastening element is machined in the central pipe. The ends are fixed to the spar. To make the drawbar, use a pipe with a cross section of 60x30 mm.

The frame is the foundation load-bearing structure. Traverses are made of steel squares (25x25 mm). To strengthen them, cross sections are used. The racks are made from pipes that are connected to 2 sides of the structure.

This coupling method allows the pipe to partially rotate without changing its position in the longitudinal direction when the walk-behind tractor moves.

Wheel axle

The wheel axle can be made of a steel rod with a diameter of at least 30 mm with axle shafts welded at the ends, onto which wheels with a hub are in turn mounted. To securely fasten them to the axles, locknuts and cotter pins should be used, and the fit on the axle should first be ground for the bearings in the caliper.

If it is necessary to install a brake, then a lever near the driver's seat, a cable system and drums should be provided for it.

As you can see, having the drawings and a complete manufacturing algorithm at hand, if you wish, you can make a trailer for a walk-behind tractor or other vehicle yourself.

Below, we invite you to watch a video on how to make a trailer for a walk-behind tractor with your own hands:

After purchasing a walk-behind tractor and checking its operating capabilities, the owner wants to supplement this useful machine with a cargo trailer.

Having received one more wheel axle, the body and seat of the walk-behind tractor turns into a universal assistant that can be successfully used all year round.

A walk-behind tractor with a trailer will successfully replace not only a mini-tractor, but also a truck. And if the trailer has a tipper, then you don’t have to swing a shovel, unloading sand or crushed stone, black soil or manure.

A factory trailer for a walk-behind tractor can have a load capacity from 300 kg to one ton and different sizes body It all depends on technical characteristics walk-behind tractor, so trailer manufacturers adapt their products to light, medium and heavy hand tractors (walk-behind tractors).

Today, therefore, there are many varieties of cargo adapters available for them. Size range The bodies of such trailers are represented by the following options.

For light walk-behind tractors, trailers with a body 1 wide and 0.85-1.15 meters long are usually used. The load capacity of such adapters does not exceed 300 kg. The cost of light carts is around 12 - 15 thousand rubles.

For trolleys designed to work with medium-power walk-behind tractors (4.8-8 hp), the body size is 1.0 x 1.5 m or 1.1 x 1.4 m with a load capacity of 300 to 500 kg. The cost of cargo adapters of this class depends on the configuration and the manufacturing company and can range from 19 to 40 thousand rubles.

For heavy machines with a power of more than 10 hp. they use single-axle or two-axle trailer trolleys with a body 1.2 wide and 2 to 3 m long. They are capable of transporting loads weighing from 500 kg to 1 ton. The price of such adapters ranges from 42 to 60 thousand rubles.

The height of the sides of standard walk-behind trailers ranges from 30 to 35 centimeters. For heavy-duty trolleys, frame side guards with a height of 50-60 cm are used.

Trailers with a carrying capacity of more than 350 kilograms are equipped with a mechanical brake. This is required by safety regulations. When moving down a steep slope, you will not be able to extinguish the inertia of a loaded trailer with just the brake of the walk-behind tractor. Therefore, when choosing a trailer for a heavy hand tractor, be sure to pay attention to the presence of this option.

Standard tipper trailer for light and medium walk-behind tractors does not have a lifting hydraulic cylinder. The body is installed in such a way that the center of gravity of the load is on the rotating axis. Such central balancing significantly facilitates the process of manual tipping.

To increase the convenience of loading and unloading, some trailer models, in addition to the rear one, also have two side opening removable sides.

Trailer bodies are most often made from painted galvanized sheet, painted black steel sheet or impact-resistant plastic. The first option is the highest quality and most durable, although the most expensive.

Self-production of a trailer for a walk-behind tractor

The design of the cargo adapter for the walk-behind tractor cannot be called extremely complex. If you have an electric welder, an angle grinder and a drill, almost every owner of a hand tractor can make a trailer for a walk-behind tractor with their own hands.

The main structural elements, the manufacture of which will require a drawing or detailed diagram are the frame, carrier and body.

1 — mounting bracket for walk-behind tractor; 2 – rotary console, 3 – carrier; 4 – footrest; 5 — seat (20mm board); 6 – trailer frame; 7 - body side made of 25 mm board; 8 — frame support beam (block 50×50mm); 9 – fixing bolt of the M8 hinge; 10 – rear hinge unit; 11 - wheel

Studying the design of the trailer for the walk-behind tractor shown in the figure, you will notice that the driver is connected through the rotary unit and the console to the trailer module of the walk-behind tractor. The second end of the carrier is inserted into the central tube of the frame.

The “pipe-in-pipe” design forms a kind of long hinge. It allows the wheels of the trailer to change their position independently of the wheels of the walk-behind tractor while overcoming holes and bumps. This solution avoids deformation of the trailer structure.

1 - swivel unit; 2 – “drawbar” (round pipe 60 mm); 3 – footrest frame (angle 25 mm); 4 – stiffeners

The articulated coupling of the walk-behind tractor with the trailer is made using a console - a steel axle. It stands in the rotating block of the carrier on bearings. A flange is welded to the top of the console, with which it is attached to the hitch of the walk-behind tractor.

To strengthen the junction of the drawbar with the body of the rotary unit, you need to use 4 stiffening ribs from a steel strip 4 mm thick.

When making a homemade trailer for a walk-behind tractor, its frame is welded using several types of rolled metal: corner, rectangular and round section. The supporting frame must be strong and rigid so that when moving with a full load, its structural elements do not deform.

1 - brace (corner 20 x 20); 2 - seat frame (corner 20×20); 3 — seat posts (corner 40×40); 4.5 - front struts (pipe 40×20); 6 — body frame strapping (angle 40×40); 7, 8 – wheel axle stands (angle 32×32); 9.10 - rear struts (pipe 40x20); 11 - reinforcing cross member (angle 40×40), 12 - central pipe 58×4; 13 - axle (30 mm rod), 14 - gusset (4 mm sheet).

To fix the carrier pipe in the central pipe of the frame, a hole is drilled through it and a bolt with a lock nut and a pin is inserted. In this case, you need to cut a long “window” in the central pipe.

In it, the fixing bolt passing through the carrier pipe will be able to move around the axis of the trailer without moving in the longitudinal direction. This is the final operation required to reliable operation the “pipe-in-pipe” hinge, which we described above.

To make a wheel axle, you need to take a high-quality steel rod with a diameter of 30 mm. It is connected to the central pipe of the frame, the platform frame from the corner and the struts by electric welding.

The fixed body can be made from 25 mm boards, or its sides can be made from a steel sheet 1.5 mm thick, welded onto vertical racks from a corner 40x40 mm. If there is a need to open the sides, then several hinges need to be welded to the frame, to which the side frame will be attached. It is necessary to weld bolts to the corners of the frame, which will fix the sides in the transport position.

In a properly balanced trailer for a walk-behind tractor, the center of gravity of the load is located closer to the front side and does not extend beyond the axis of rotation of the wheels. This requirement must be taken into account when drawing up a drawing of a homemade structure.

You can use passenger car wheels as trailer wheels by purchasing them complete with hubs. Before installing the wheels on the axle, you need to carefully sharpen it seats under inner diameter bearings wheel hubs and provide a lock nut with a locking cotter pin.

From the beginning of spring until late autumn, life is in full swing in gardens and summer cottages. You constantly need to bring something, transport it, take it away, and the like. IN Lately most summer residents use it for economic needs walk-behind tractors, walk-behind cultivators and other devices. They are compact, easy to operate, multifunctional and do not take up much space. The products of the domestic enterprise Neva are most often used. The trailer for the Neva walk-behind tractor will be a good help in your household. In this article we will tell you everything about this equipment.

a brief description of

Why do you need this unit? Due to its versatility, the trailer for the Neva walk-behind tractor can be used for a huge number of different jobs:

• moving cargo;
• removal of household waste;
• transportation of agricultural products and equipment;
• auxiliary work.

At the same time, it should be noted that it is not recommended to drive a walk-behind tractor onto a busy highway. This is due to the fact that the Neva walk-behind tractor with a trailer has limited speed and maneuverability.

Among the rather impressive model range For trailers, the most popular units are those with a load capacity from two hundred and fifty kilograms to half a ton. Their towbars are made of special metal, which is characterized by increased strength.

For better controllability of the walk-behind tractor, a brake system is installed on the body axle.

The trailer for the Neva MB 2 walk-behind tractor is in great demand among gardeners. Its special feature is the presence of folding sides. This makes it possible to transport both small and bulk cargo, as well as objects of impressive size.

Manufacturing

If you have everything you need, you can assemble a dump trailer for a walk-behind tractor with your own hands. It will meet all your requirements.

First of all, you will need the following tools:

• channel number five;
• jigsaw;
• welding machine (for convenience it is better to use a semi-automatic device);
• screwdriver;
• Bulgarian.

Having prepared necessary tools you need to determine the dimensions of the trailer. The parameters of parts and workpieces will depend on them. For work, you can use drawings of the simplest models of the unit, which are found on the Internet at every step. See the best options, but you can do without them:

Sequence of operations

First of all, you need to assemble the frame. Smaller tubes (based on the design we describe - 25X25 millimeters) are used as front and rear crossbars, and two larger tubes will become spars. All structural elements are fastened using welds. As a result, you will get a kind of lattice.

After this, you can proceed to manufacturing the body. The frame is strengthened by attaching twenty-five millimeter pipes to it perpendicular to the grid mesh. Then to them using welding machine longitudinal pipes are attached, and four racks are attached to them. The strapping is welded to the tops of the posts.

A dump trailer for a walk-behind tractor must have folding sides, preferably not only at the back, but also on the sides. To achieve this goal, you need to use a welding machine to connect narrow pipes into three rectangular structures separately from the body.

We use duralumin to cover the frame - making the bottom - and iron sheets for the sides. As fastening elements It is better to use bolts. To attach the sides to the posts and trim, you will again have to think about welding.

After this, you can begin to mount the beam. To do this, you need to insert two channels into each other. Wheel axles are attached to the rear end of the resulting structure. After this, the beam is welded to the trailer frame using springs.

Now you need to equip the dump trailer with a drawbar. The algorithm of actions is very simple. Take two pipes with dimensions of sixty by thirty millimeters. Their front parts are mated and welded to the base of the coupling device. The rear parts of these pipes are attached to the side members with an overlap of two hundred millimeters.

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 for performing various types of work. 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 the correct drawing up of a drawing or sketch. The main work should begin, strictly adhering to the intended dimensions. To simplify the process, you can take as a sample factory model carts. 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 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 describe the necessary spare parts and tools.

Before purchasing materials and creating drawings, you need to examine the available parts, since any hardware 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.

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.
• The rotary assembly is a complex element that requires 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 preparing the necessary parts and tools, you can begin to work, but it is very important before work to clean the metal from rust 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 car can be made from suitable metal or boards with a cross section of 20 mm. When making from boards, it is necessary to strengthen the structure with 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 if installed incorrectly, lifting the body can 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 handles of a cultivator, since it needs to be attached to a hinged console. At the attachment point between the bearings it is necessary to apply grease and cover it 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 connected by welding. If you select other wheel pair options you can perform the following operations:

1. Attach the angle to the transverse part of the frame or weld a piece of pipe.
2. 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 with a thickness of 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. When creating a folding structure, it is necessary to weld the lock and use a steel pin with a cotter pin.

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 or a small household plot, 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. Manufacturing homemade trailer on your own - it’s 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 issues 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.

Therefore, in 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, most of the connections (if not all) can be made without a welding machine, using bolts; The process of covering the trailer frame with the selected material, be it sheet iron, corrugated boards 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, the following parameters are sufficient: 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 top harness racks Suitable for these purposes. Depending on the size of the trolley - 15 or 25.

Pair of wheels

To attach the axle, you will have to install special supports at the bottom of the frame. They are welded to it (in the form of gussets), so in this case a bolted connection is unacceptable. The photo explains how everything can be arranged (option).
