How to make a trailer for a walk-behind tractor with your hands. Do-it-yourself trailer for a walk-behind tractor from improvised materials

The purchase of a walk-behind tractor as a necessary means of production has become a necessity for many, but for the normal operation of the unit, it is imperative to buy a trailer in the kit. However, the proposed models do not always take into account the necessary features, and this is one of the reasons that many owners of such assistants prefer to independently design a trailer for a walk-behind tractor with their own hands.

• trailer frame;
• body;
• axle and chassis;
• hitch.

To facilitate the work, you must purchase or use ready-made elements:

• car wheel hubs;
• wheels assembled with tires;
• hitch to the car.

Types and purpose of models of the main structures of motoblock trailers

The main types and models of do-it-yourself trailers for walk-behind tractors are classified according to the type of homemade body part designs:

• one-piece structures;
• transformer structures with folding sides;
• dump body types.

The one-piece construction of the trailer includes the presence of a rigid non-removable body of the sides. Due to the rigidity of the design, the trailer allows you to transport goods both in bulk and in packaged form. The body has a large rigid frame platform, welded to the side railings. For loading and unloading, a folding tailgate is provided.

Transformer structures are trailers for universal use, they have the functions of both a trailer with a rigid body and a platform for transporting bulky goods. The frame base is a rigid base, and folding or removable sides, when transformed, form an additional area of ​​a flat platform.

The tipper type of motoblock trailers allows tipping and unloading bulk cargo without additional effort.

Assembling a homemade trailer for a walk-behind tractor

Starting to implement the project, the master-do-it-yourselfer needs:

• create a working draft or drawing (drawing);
• prepare material for the frame and other main components;
• prepare a workplace;
• to mark the main elements of the trailer design;
• lay out and adjust the alignment angles;
• assemble part templates;
• carry out the adjustment of the acquired assemblies to the structural elements.

Necessary tools and materials

To carry out the work, it is necessary to prepare all the necessary tools:

• welding machine;
• grinder with a set of cutting and abrasive discs;
• measuring tool - tape measure, metal ruler, protractor, square, marker and chalk, metal scriber;
• hammer, chisel, pliers;
• metalwork vise, set of clamps, welding clamps;
• drill, a set of drills for metal;
• riveter.

As necessary materials you will need:

• steel square or rectangular pipe 60 × 60 or 60 × 30 mm;
• steel square pipe 30 × 30 or 25 × 25 mm;
• corner 25 × 25 mm;
• channel;
• springs of the car "Moskvich";
• steel sheet 2 mm thick;
• galvanized sheet 1 or 0.8 mm thick;
• fasteners, bolts, nuts, rivets.

For a rigid body model, instead of a spring-loaded wheelset design on springs, you will need a regular beam.

For trailer wheels, ready-made car wheels from a Tavria, Moskvich or Zhiguli car are suitable.

Wheels must be selected immediately with hubs, this will facilitate the further assembly of homemade products.

Frame

The trailer frame is an all-welded construction in the form of a square tube frame lattice. Traverses from a square of 25×25 mm form the cross members of the frame, and the spars are made from a pipe 60×60 or 60×30 mm. All structural elements after marking are cut and laid out on a flat surface, the joints are welded with small seams, each junction of the elements is checked with a square. After the assembly of the structure, the final welding of all parts along the perimeter of all planes is carried out. The frame is painted after surface treatment with a primer for metal.

Chassis

In the manufacture of a homemade trailer for a walk-behind tractor, the chassis is the most difficult element.

The basis of the chassis is a beam with hubs at the ends. The channels are joined to each other in such a way that they form a square. The joints are welded with a continuous seam. Wheel hubs are installed at the ends of the axle and welded.

The thoroughness of the axle assembly is checked by checking the parallelism of the planes of the rims. The connection of the frame and the beam is carried out with the help of springs, while the ends of the springs are installed in welded brackets on the frame, and the beam is pressed against the central part of the springs with the help of an earring.

The undercarriage mounted on the frame is additionally tested for tipping stability. As in a car, the axle spring group must have rubber bushings in the frame mounting bracket.

Body, frame trim

The platform is marked relative to the grid in such a way that allowances are left for attaching the side racks. The front and side boards are installed tightly, and the rear board is made removable on the door hinges.

The sides of the trailer have a frame structure of 25×25 mm corners. The corners are welded end-to-end, the seams on the inside are cleaned according to the level of the metal plane.

Removable sides are assembled in the following sequence:

• board frame;
• the galvanized iron sheet is adjusted to the size of the frame;
• the side cloths are cut out and fixed with rivets through the corner.

The bottom of the body made of a sheet of 2 mm iron is mounted on the frame and welded with a small seam around the perimeter every 3-5 cm.

The installation of the boards begins with the installation of the front board, then the side boards are installed and connected by welding.

The tailgate is fixed last - first, the loops are marked and welded, and then the latches.

Other construction details

After assembling the frame and body, a folding seat is installed - a wooden bench placed on top of the front side with support on the side ones.

As a trailer braking system, it is recommended to use elements of the braking system of a car whose hub and wheels are used in the design. For reliable operation of the brake system, it is recommended to provide an additional lever lock.

Attaching a trailer to a walk-behind tractor

The drawbar of the trailer, like the frame, is made of pipes 60 × 60 or 60 × 30 mm. This is a double-beam design with a connection in the hitch. The coupling device is installed at the point of convergence of the drawbar beams. The rear ends of the pipes are welded with an overlap and reinforcement to the side members of the trailer.

The articulation of the trailer with the hitch of the walk-behind tractor must ensure the ease of turning the mover during movement and, at the same time, the reliability of the connection with the trailer.

In a simple version, an earring made of a metal bar or reinforcement with a diameter of at least 20 mm can be used as a standard hitch. As an option, a standard hitch for car trailers and a towbar is used.

For reliable articulation and ease of control of the walk-behind tractor, a pipe with a diameter of 40 mm and a length of 100 mm is welded in at the junction of the drawbar beams. Inside the pipe on two bearings, the axle of the towing device is installed. From the side of the trailer, the pipe is jammed with a washer to fix the axle of the towing device, the diameter of the washer hole corresponds to the diameter of the axle of the towing device.

The axle of the trailer towing device on one side has a thread for fixing with a nut with a stud, and on the other side it has a welded hitch for attaching to a walk-behind tractor.

The hitch at the end of the axle facing the walk-behind tractor is made of a 60 × 60 mm square pipe 80 mm long. A through hole in the pipe, drilled through two opposite sides, must correspond to the diameter of the fixing pin of the walk-behind tractor hitch and fit securely inside the hitch. Inside the square tube is reinforced with additional metal plates. The edges of the pipe are rounded so as not to create additional difficulties when turning.

From the side of the trailer, the axle of the towing device is fixed with a nut and a fixing pin.

As a result, when connecting the tow hitch of the trailer to the eye of the hitch of the walk-behind tractor and fixing the hitch with a finger, the walk-behind tractor and the trailer must be securely connected, while driving, ensure stability and ease of control.

When planning the purchase of a walk-behind tractor, you almost always have to think about good attachments for full-fledged work on the land. Attachments for a plow and a trailer for a walk-behind tractor are needed like air. You can’t argue with this statement, but they cost a lot, and it’s not always possible to carve out money to buy such a gun carriage from the limited budget of an ordinary person. Therefore, it is better to spend the bulk of the capital on acquiring a cool powerful motor unit with an American or Japanese engine, and make a trailer for a motor block with your own hands. Moreover, finding drawings for any version of a trailer for a walk-behind tractor is not a problem.

Trailer options for motoblock

Depending on the planned transportation volumes, the method of using the trailer and the capabilities of the walk-behind tractor, several different options can be made:

Important! The main reason why trailers for a walk-behind tractor fail is that a 120 kg carriage is loaded with more than the carrying capacity and dimensions of the trailer allow.

The heavy option will allow you to transfer at once the attachments, the plow, and the entire stock of potatoes for planting. The service life of such a machine is calculated in tens of years.

Trailer frame: 1 - brace (corner 21x21x3), 2 - seat frame (corner 21x21x3), 3 - riser (pipe 50x25x4), 4 - seat posts (corner 40x40x4), 5.14 - front struts (pipe 50x25), 6, 15 - longitudinal spars (corner 40x40x4), 7.8 - right wheel axle supports (corner 32x32x4), 9.16 - rear struts (pipe 50x25), 10 - reinforcing cross member (corner 40x40x4), 11 - body of the longitudinal hinge (pipe 58x4 ), 12 - wheel axle (bar with a diameter of 30), 13.17 - transverse spars (corner 40x40x4), 18 - scarves (s4)

How to make a trailer for a walk-behind tractor with your own hands

To build a heavy and stable trailer for a walk-behind tractor, we need the following equipment and materials:

1. Electric welding machine, grinder, electric drill with a set of drills, with a dozen electrodes No. 4;
2. Steel profile - tubular square 40x40 mm. -20m, 20x40mm. -15m., steel pipe with an inner diameter corresponding to the outer size of the hub bearing, sheet metal 2mm thick. and a total area of ​​2x3m.;
3. Two complete hubs, from an M2140 or M412 car, a pair of Moskvich wheels with “live” rubber, two pairs of canopies for garage doors.

Work on the manufacture of a trailer for a walk-behind tractor with painting work will take at least three days. The main dimensions of the trailer are clear from the diagram, the load capacity of the above diagram is at least 500 kg, more weight is dangerous for a conventional walk-behind tractor. If you purchased a ZUBR or Garden Scout GS 101DE motoblock with a 12 horsepower diesel engine, you can load more.

We assemble the frame according to the drawings and photos

At the initial stage, it is necessary to cut the material and weld the skeleton for the cargo compartment of the trailer by electric welding. It is a rectangular frame welded from a square section metal profile. If you follow the drawings, you get 120x180 cm. We will make 150x200 cm. Inside the rectangular frame, you need to make two transverse spacers, as in the photo. This will strengthen the bottom of the cargo compartment of the future trailer.

Next, cut out from the profile 40x20mm. and weld four sides, each 500 mm high. The sides are sewn up with steel sheets and welded to the base of the cargo compartment, a sheet of metal is laid on the bottom and fastened to the metal profile beams. The tailgate can be mounted on large door awnings, allowing it to be folded down when unloading. All welded parts of the structure are carefully treated with a rust converter and coated with a primer.

At the next stage, it is necessary to cut out from the metal profile and weld the towing device for attaching to the walk-behind tractor and the supporting frame, on which the previously manufactured trailer cargo compartment will be installed.

The shape and dimensions of the supporting frame, and the method of attaching the trailer to the walk-behind tractor are clear from the photo. The dimensions of the square part of the frame correspond to half of the cargo compartment.

Canopies must be carefully leveled and welded with the highest welding quality. Thanks to this rationalization, the cargo compartment of the trailer will be able to tip over for unloading without changing the position of the walk-behind tractor.

We make the undercarriage of the trailer to the walk-behind tractor

The trailer will be made on rubber running, this will greatly simplify the control of the walk-behind tractor, increase safety and comfort when driving. Wheels with hubs on two support bearings provide minimal rolling resistance, so even with a fully loaded cargo compartment, the walk-behind tractor will quite easily pass through the primer or even grassy soil.

This option does not use full-fledged braking devices, but technically there is such a possibility, and if you wish, you can supplement the hubs with covers and brake pads from the M412. In order not to mess with the hydraulics, you can use a cable drive from the hand brake.

To install a pipe with bearings and hubs on a trailer, it is necessary to first cut and weld to the frame three supporting vertical posts made of metal profile 40x40mm, each 120-150 mm high. When installing the pipe, a lot of patience will be required to accurately position the undercarriage parallel to the cross member of the trailer frame. The tubular axle allows for high strength and rigidity even when the maximum load is doubled or when cornering at a high speed, as for a walk-behind tractor.

Next, we weld the pipe, install and adjust the position of the hubs in the pipe so that the runout of the wheel disk, dressed and screwed with nuts on the hub, is minimal. Immediately after leveling is completed, tack the seam with welding points and weld a full seam.

To reduce the load on the vertical racks, it is necessary to cut and weld reinforcements in the form of a metal profile from the pipe to the frame frame.

To attach a trailer to a walk-behind tractor, you can remake a standard hitch based on a plow or make an adapter like a towbar. The main condition is that the connection must be able to freely rotate in a horizontal plane, not interfere with the control of the walk-behind tractor and be strong enough, given the large weight of the structure.

On the triangle of the trailer, you must install a vertical stand with a bench or seat for the driver. The height and location of the seat is chosen based on the length of the walk-behind tractor control knobs. It is recommended to close the space under your feet with a metal mesh or welded thin fittings.

Conclusion

Driving a heavy carriage to a walk-behind tractor will require a certain skill, so the first attempts should be made exclusively in deserted areas. In addition, for this kind of construction, traffic police officers may require registration and equipment of a gun carriage for a walk-behind tractor with dimensions, brake lights, and brakes.

In the garden or in the garden, a walk-behind tractor is one of the most useful things. With its help, you not only easily cultivate the land, but also transport a lot of necessary things: hay, fertilizers, potato crops, fuel ... But how can this be done if a standard walk-behind tractor does not have a trailer? There is a way out - a do-it-yourself cart for a walk-behind tractor is made (the drawings are given below) quite simply, and this will save a lot of money.

A simple do-it-yourself cart for a walk-behind tractor drawings

A trolley for a walk-behind tractor can carry a load of 400-450 kg plus the weight of the driver. She easily carries six or seven sacks of potatoes without reloading.

The blank for the wheel axle is a steel circle with a diameter of 30 mm. With an axle length of about a meter, the wheels are under the body. The wheel axle with angular bearings and a gusset is welded to the spars and the body of the longitudinal hinge.

Body

It is knocked together from 20mm boards, on the corners of which steel corners are attached. The bogie body is attached to the frame through three strong support beams made of 50x50 timber.

wheels

They are taken from the motorized stroller together with the hub assembly. Both ends of the axle are sharpened to match the diameter of the hub bearings.

Hitch with walk-behind tractor

The coupling of the trolley and walk-behind tractor is provided by the console. Its upper part repeats the contour of the holder of the hiller, as it is fixed in the standard bracket of attachments of the walk-behind tractor. Around the lower part in the form of an axis, a rotary carrier assembly is fixed in two RUE-bearings. The space between RUPs is filled with grease and closed from the outside with anthers.
Under severe operating conditions of the trolley, its connection and the carrier must be articulated.

The drawbar is inserted inside the tubular body of the longitudinal hinge, it is fixed with a thrust ring. This design leads to the independence of the wheels of the cart from the wheels of the walk-behind tractor, which, when driving over bumps, greatly simplifies the control of the walk-behind tractor.

The driver sits on a semi-rigid wooden seat cushion in front of the body. The driver's hands hold on to the levers of the walk-behind tractor, and with his feet he leans on the footboard made of wood in a frame from the corners on the drawbar.

Do-it-yourself trolley for a walk-behind tractor

The simplest trolley for a walk-behind tractor can easily carry loads weighing up to 400 kg.

Structural parts of the bogie

In any bogie, the following components can be conditionally distinguished: a driver's seat mounted on a welded frame, a central frame, the bogie itself with a body and wheels.

What material is the frame of the trolley made of?

The easiest way is to cook it from a channel and a corner, which you can buy at any building materials store. The frame is welded with the utmost care, as it must withstand the stress of driving over bumpy country roads.

Blank for wheel axle

For it, you can take a steel circle with a diameter of at least 30 mm. The axis is connected by welding with a longitudinal hinge and with corner supports. It is necessary to select the length of the axle so that the wheels are under the body.

How to make a trolley body

With your own hands, the body is most easily assembled from boards up to 20 mm thick, steel corners are installed at its corners. The boards are bolted to the frame. It is better to make the sides folding: it will be more convenient to unload large volumes of goods.

wheels

You can use them from any agricultural machinery. Wheels from a conventional sidecar from a motorcycle are quite suitable. The axle will need to be turned to fit the diameter of the bearings in the wheel hubs.

trailer hitch

It is made from any suitable piece of metal by drilling a hole in it in which the hitch can easily pass. It is desirable to make a swivel assembly from a bearing with a suitable diameter, fixing it as firmly as possible by welding.

Cart bottom

Of course, it can be made from edged boards. But a more durable bottom is best made from sheet metal with a preferred sheet thickness of two to three millimeters. Such a cart for a walk-behind tractor, which you yourself can make in two or three days, can last for several years and with little or no repair.
