How to make a drawbar for a power tiller trailer

Cart for a motor-block with their own hands: dimensions, drawings, video

A single-axle tractor is one of the most useful and inexpensive technical devices used when working on homestead plots and gardens. It is used not only for tillage and harvesting, but also for transporting hay, fuel and other heavy items. The standard unit does not require a trailer, but anyone with even a little understanding of the design and operation of mechanisms, can make a cart for a power tiller with their own hands. Its construction is quite simple.

To begin with, you need to refer to the drawings of the cart and sketches, according to which the production will be carried out. It is necessary to think about the load capacity, the dimensions of the device, and their compatibility with each other, focusing on the mechanisms made in industrial plants.

Making a homemade cart for a power tiller will save a lot of money, without spending a lot of effort and time.

Trailer for passenger car with their own hands: manufacturing options, schemes and optimal dimensions

Drivers solve the problem of lack of space in the trunk when transporting large and heavy loads with a trailer. At the car market or in a specialized store there are factory models, which have passed certification tests and are prepared for registration. However, the high price or unsuitable capacity forces owners to assemble a trailer for a passenger car with their own hands. When self-made, the master himself will select the options and layout scheme, as well as the optimal dimensions of the construction.

Features of manufacture

Self-assembly of the trailer is due to several factors: an attempt to save money, implement their own ideas or demonstrate their own skills. But the main reason is the high price of the factory models. If you have the necessary amount of money and time to buy a trailer platform, you can order the construction of any configuration.

Savings might not be so high if you assemble it yourself. All critical components must be certified, and you will have to buy them officially. If you add up all the costs of acquiring materials, as well as the costs for testing, you get an amount comparable to the price of a new trailer. However, the self-made construction has several advantages:

  • Individual approach to the definition of dimensions. The bodybuilder decides for himself what the dimensions of the car trailer will be.
  • The choice of accessories. The design is equipped with freely available components, which are sold at the automotive markets.
  • Simplicity. The design, made in a garage, has no complex components, which facilitates its maintenance and repair.

The trailer, assembled by yourself, can not be used without registration at the appropriate authorities. Hence the disadvantages of homemade production:

  • The design must comply with strict norms and standards, which imposes strict restrictions on the layout of the trailer.
  • All units must be tested for compliance with current GOSTs.
  • Accessories must be factory made, have the appropriate documents proving their authenticity. Using “junk” accumulated in the garage is not possible.
  • There are problems with registration.

An important point when putting it into service is to register it. Legalize homemade construction is real, but you need to be prepared for the fact that it will take a lot of time and effort. Algorithm of registration of the trailer:

  • Prepare a package of documents consisting of receipts, passports and certificates of parts used in the assembly.
  • Make photos of the trailer from all angles, as well as a brief description specifying the characteristics.
  • In the traffic police get a list of documents required for registration and direction to pass the certification tests.
  • Submit, along with the prepared documents, an application for tests to the testing lab.
  • Employees of the certification center will conduct all the necessary tests, will issue an expert opinion on the compliance of the homemade construction with current standards. If the trailer does not pass the tests, the lab will not give you a permit, and the design will have to be modified.
  • With the certificate of conformity return to the traffic police. There they submit an application for registration. It should be accompanied by copies of the documents. Inspection staff will inspect the trailer and issue a license plate after the registration.

What you need for assembly

First of all it is necessary to get acquainted with GOST R 52281-2004. This is a fundamental document, for compliance with which the homemade trailer will be checked in the certification laboratory. It is better to print it out, so you always have it handy. The current version of GOST can be downloaded from the Internet or you can ask for a copy from the same laboratory where the tests will be conducted.

Based on the standard, sketches and drawings of the future construction are developed. In addition, ready-made solutions can be found on the Internet, where other craftsmen place their projects. The drawing is drawn to scale with the dimensions and weights of the parts. In this way it will be possible to calculate the weight of the self-made trailer before the start of work, in order to adjust the layout for maximum strength and rigidity.

After drawing up the drawing, proceed to prepare the necessary materials. In the general case will be needed:

  • Rolled metal for the frame. The trailer frame is assembled from a steel profile pipe with a cross section of at least 40×40 mm, an angle, channel or I-beam.
  • Undercarriage. Cargo platform is installed on a homemade or factory-made chassis. In the first case, the axle is assembled from a thick-walled metal pipe and rear hubs from the front-wheel drive car. You can get the prefabricated axle from a small car.
  • Material for the frame of the boards. Frames are made of profile pipe with a small cross section.
  • Bargain hitch.
  • The underbody and side trim. It is allowed to use steel sheet of thickness not less than 0.6 mm, sawn wood (boards, plywood).
  • Wheels.
  • Electrical part (wires, lights, connector for connection to the car’s onboard power system).
  • Wings with mudguards.

To assemble the trailer you will need a variety of tools and supplies. The master needs to prepare the equipment for work with metal: an angle grinder, a welder, a drill or a screwdriver. It is necessary to buy cutting-off wheels, electrodes (wire with gas for a semiautomatic machine). If the boards will be trimmed with lumber, you will need woodworking tools. You’ll also need wrenches, screwdrivers, and metal fasteners.

Possible packaging

You can make a trailer of various configurations. They can be single- and two-axle, monolithic design or with a tilting platform, with wings or wheel recesses placed inside. Layout depends on the purpose for which the trailer is made and its intended load-carrying capacity. The chassis must be able to withstand dynamic and static loads.

Examples of the diagrams of supporting elements and suspension mountings can be found in the ready made works published on the internet. But it is not necessary to determine the dimensions by photo. It is not superfluous to look at the serial design of the factory production. The natural instance can be found at acquaintances or ask to take measurements of exhibition models, presented in the market or in specialized showrooms.

Homemade trailer for a “Neva” power tiller: drawing. How to make a trailer for a power tiller? :

The trailer for the tiller may become an indispensable assistant in the household plot. It can be used for many purposes, for example the transportation of seedlings, as well as crops. In addition, such a trailer will easily cope with the transportation of heavy tools and garbage. If you spend some time on the manufacture of the above equipment, you will greatly facilitate your work on the site. In this article we will tell you how to do it.

Making the simplest model trailer

If you do not have the desire to spend a lot of effort in order to make a trailer for a power tiller, you can apply in carrying out the work the most simple instructions presented below.

Thus, for the manufacture to prepare the metal pipes with the following dimensions: 60×30 and 25×25 mm. You’ll also need springs and wheels, which can be borrowed from the car “Moskvich”.

Always prepare a duralumin sheet with a thickness of 2 mm. The master must also take care of the availability of the cut sheet metal, the thickness of which is equal to 0.8 mm.

There is no way to make a trailer for a power tiller without using a channel. In addition, you will need and fasteners, but among the tools can be distinguished:

Tips for the work

The first thing to do is to make the frame, which is a one-piece system. The latter should be placed on the frame grid. To make it need to make beams in the number of a pair, but it is necessary to apply at the same time, the angle, the dimensions of which are 25×25 mm. These elements will act as the rear and front crossbars. It is necessary to make and spars, in which process a pipe with parameters equivalent to 60×30 mm is used.

It is recommended that all these parts are connected by means of five crossbars. Do it in such a way that it would end up with a lattice. Such a simple structure is quite simple to make, in addition, it will have hinged sides.

Making the platform

When making a trailer for a power tiller, it is necessary to make the arrangement of the grid, which involves the attachment of traverses and crossbars relative to the longitudinal members in such a way that there were insignificant releases.

To these eventually have to be attached through the use of a welding machine longitudinal pipes.

To the latter in the same way fixed racks of four pieces, but to their upper part to strengthen the welded strapping made of angle with a size of 25×25 mm.

Making the hinged sides

In order to make homemade trailers for power tillers, which will have hinged sides, the frame must be made separately from the frame. The duralumin sheet is to be used in the finishing of the grillage of the platform, but it is recommended to make the fastening by means of bolts. In order to finish the sides, it is acceptable to use not so thick steel sheets. Fastening is carried out on the strapping strips and the uprights by means of a welder.

In order to get a beam, when making homemade trailers for power tillers, it is necessary to use two channels, which must be equal in length to each other. They should be inserted into each other, supplementing one of the ends of the structure with wheel axles. Use leaf springs to mount the prefabricated beam to the side members. To do this, the ends of the springs should be put on the bracket axle. The axle of the frame, which concerns the central area, should be welded to the beam, using stepladders.

Final stage of manufacturing

Working on the drawbar, it is necessary to apply rectangular tubes, the dimensions of which are equal to 60×30 mm. In order to obtain a double-beam design, the front ends of the tubes should be pre-mated, and then reinforced by welding to the base of the drawbar equipment.

After that, you can proceed to the rear ends of tubes, which should be welded to the front ends of longitudinal members, providing 200 mm overlap. At this point we can consider that the trailer is ready.

If there is a need and desire, the design can be supplemented with stop lights, parking lights, as well as turn signals.

Making a more complex trailer

The trailer for the motor block “Neva” can also be more complicated. Initially, too, it is necessary to prepare materials and tools. A welding machine will also come in handy, as self-tapping screws will not be able to provide such a strong connection.

To obtain a reliable frame will need metal angles 50×25 mm, you will also need those that have a size of 40×40 mm. It is recommended to prepare scraps of round and rectangular pipes.

The body can be made of 20 mm boards, you also need a 50×50 mm beam for the support beams.

Work on the basic elements

The trailer for the “Neva” power tiller must have the following basic components. Among them, you can highlight the wheels, the body, the driver, as well as the frame. Each of them must be connected by means of a welding machine.

In order to increase the strength of the equipment, in the area of coupling the body of the rotary unit with the drawbar must be strengthened stiffening ribs in the number of four pieces. The body has a kind of wooden structure, which is assembled from 20-mm boards.

To make the corners more solid, they should be equipped with metal corners.

Before you make the trailer for power tillers, you should consider that the frame and body are attached through three bars, which are represented by support beams. The frame of the structure is to be made of a set of metal elements. Among them are bars, pipes, as well as corners.

Due to the fact that the trailer looks like a single-axle structure, the load must be distributed so that the center of gravity was shifted forward, not beyond the axis of the wheels.

The main disadvantage of such a body is that it can not be equipped with folding sides.

Work on the running gear

The drawing of the trailer for the power tiller must be prepared in advance. The next step is to begin work on the running gear. The wheels and springs can be bought new, you can also use the wheels borrowed from SZD sidecar.

Trailer for power tillers with his own hands

Planning to buy a walking tractor with a walking tractor you almost always need to think about a good attachment for full work on the plot. Connected equipment for a plough and a trailer for a crawler tractor are needed like air.

You can not argue with this assertion, but they cost a lot, and the money to buy such a carriage is not always possible to squeeze out of the limited budget of the average person.

Therefore, it is better to spend the bulk of the capital to purchase a cool powerful motor with an American or Japanese motor, and make a trailer for a motor-block with their own hands. The more so that the drawings for any variant of the trailer to the motor-block to find. not a problem.

Depending on the planned volume of transportation, the way of using the trailer and the capabilities of the motoblock, you can make several different options:

The heavy version will allow to move all the mounted equipment, plough, and the whole stock of potatoes for planting at once. The service life of such a machine is counted in dozens of years.

Trailer frame: 1. strut (angle 21h21h3), 2. frame seat (21h21h3 angle), 3. riser (pipe 50h25h4), 4. props seat (corner 40h40h4), 5,14. front struts (pipe 50h25), 6,15. longitudinal side members (corner 40h40h4), 7,8. support wheel axis right (32h32h4), 9,16. back braces (pipe 50х25), 10. cross-bar reinforcing (angle 40х40х4), 11. longitudinal joint body (pipe 58х4), 12. wheel axle (rod with diameter 30), 13,17. transverse side members (angle 40х40х4), 18. braces (s4)

To build a heavy and stable trailer to the motor-block, we will need the following equipment and materials:

The work on the construction of the trailer to the tiller with the painting work will take at least three days. The main dimensions of the trailer are clear from the diagram, the load capacity of the given scheme is not less than 500 kg, a larger weight for a usual power tiller is dangerous. If you bought a single-axle tractor like “Zubr” or “Garden Scout GS 101DE” with 12-horsepower diesel, you can load more.

The initial step is to cut the material and weld the frame for the cargo area of the trailer. It is a rectangular frame welded from square steel profile. If you follow the drawings you’ll get 120×180 cm. We are going to make 150×200 cm. Inside the rectangular frame you need to make two cross spacers, as on the photo. This will strengthen the bottom of the cargo area of the future trailer.

Then we cut it out of the 40×20 mm profile. and weld four sides, each 500 mm high. We’ll sew up the sides with steel plates and weld them to the base of the cargo area, lay a sheet of metal on the bottom and fix it to the beams of metal profile. The tailgate can be mounted on large door hangers, which will allow it to tilt when unloading. All welded parts of the construction are carefully treated with a rust converter and coated with primer.

The next step is to cut out and weld the trailer device for attachment to the power tiller and the supporting frame on which the previously made trailer cargo section will be mounted.

The shape and size of the supporting frame and the way of attaching the trailer to the power tiller are clear from the photo. The size of the square part of the frame corresponds to half of the cargo compartment.

Next, invert the finished trailer cargo area, place the frame on top of the frame and mark the places on the frame for attaching the garage awnings, as shown in the photo.

The overhangs must be carefully leveled and welded with maximum weld quality. Thanks to this rationalization the cargo area of the trailer will be able to tilt for unloading without changing the position of the power harvester.

Making the running gear of the trailer to the tiller

The trailer is rubber-tracked for easier and safer handling and greater driving comfort. The wheels with hubs on double track bearings provide minimal rolling resistance, so even with a fully loaded load compartment the single axle tractor is quite easy to pass on dirt or even grassy ground.

This variant does not use full-fledged braking devices, but technically it is possible, and if you want you can supplement hubs with covers and brake pads from M412. To avoid messing with hydraulics, a cable drive from a handbrake can be used.

To install the pipe with bearings and hubs on the trailer three vertical posts made of 40x40mm steel profile should be pre-cut and welded to the frame., each 120-150 mm in height.

When installing the pipe, a lot of patience will be required to accurately position the undercarriage assembly parallel to the transverse beam of the trailer frame.

A tubular axle provides high strength and rigidity even if the maximum load is twice as much or when cornering at high, as for a power tiller, speed.

Next, we weld the tube, install and adjust the position of the hubs in the tube so that the runout of the wheel disc, dressed and tightened with nuts on the hub, would be minimal. Immediately after completing the alignment, tack weld the seam with welding points and weld a complete seam.

To reduce the load on the vertical struts, you must cut and weld reinforcements in the form of metal profiles from the pipe to the frame of the frame.

To attach the trailer to the power tiller, you can modify a standard hitch based on a plow or make an adapter similar to a towbar. The main condition. the connection must be able to turn freely in the horizontal plane, not to interfere with the control of the power tiller and be strong enough, given the heavy weight of the structure.

On the triangle of the trailer, you must install a vertical post with a bench or driver’s seat. Height and location of the seat are selected on the basis of the length of the control arms of the walking tractor. It is recommended to cover the space under the legs with a metal mesh or welded thin rebar.

Purpose

Trailer on a single-axle tractor with their own hands makes it possible to carry a variety of cargo:

Transportation of these loads is necessary not only in a private home, but also on summer cottages and country houses. Therefore, a trailed cart will be a reliable helper in any household.

The main parts of the cart

The typical design of a cart for a power tiller consists of a certain set of elements, but it is not difficult to remake it to suit your needs. For example, the owner of a power tiller may decide that additional components are needed. The main parts will be as follows:

  • Suspension. It can be axial or gantry type. It is allowed to install a shock absorber, but with them the load capacity will be reduced, and the entire design will be more complex. Elastic elements are not required if the owner plans to ride at a low speed, while the tires of the wheels have a fairly high profile.
  • Frame. It is welded from a piece of profiled tube.
  • The body. Versions: with folding or fixed flanks. Materials: steel plate, timber or plywood. Join the metal together by welding, and the wood together by using a metal angle. The steel cart looks solid and is more reliable. The disadvantage. a lot of weight.
  • Drawbar. This component connects the single-axle tractor and trailer. Length should be chosen so it is convenient to turn.
  • The seat. It is fixed to the bogie or hitch.
  • The rudder. The most important thing in designing this mechanism is to ensure that on an uneven terrain there is no risk of deformation, and that there are no increased torsional loads. The task of steering mechanism is to provide horizontal articulation of hinge type with two degrees of freedom.

The cart rests on two or four wheels. Accordingly, it is made with two or four axles. What to choose, the owner of the power tiller decides for himself. The four-wheel version is more stable, but more difficult to build. Also, a two-axle cart weighs more than a two-wheeled cart. It is recommended to be guided by the power of a power tiller.

Blueprints for tractor hitch

Consider the drawing of a universal coupling for the following types of power tillers: “Pubert Quatro”, “Honda”, “AGRO”, “Oka”, “Cascade”, “MB-90”, “Neva”, “Favourite”, “Salut”.

General-purpose drawbar hitch is designed to connect one or two row attachments to the power tiller: digger, plow, one- or two-row tiller, etc.

Coupling on single axle tractor

The drawbar eye must be attached to the power harvester’s bracket and secured with pins. It is desirable to fix the hitch bracket with spacing bolts M12x60, screwed to the frame of the power tiller.

Tool mounting on coupling

You need to install a removable hitch axle on the stand bracket. In the hole of the body of the hitch you need to insert the axle with a thread of M16 and screw into this thread. Align the holes for the M16x40 bolt on the implement leg and the coupling body. After that this connection is secured with an M12 nut and an M12x40 bolt.

Advice for your work

Set and adjust the attachments individually depending on the soil type and power of the tractor. The special design of the coupling can be adjusted in different ranges. Using the initial settings, set the radius slots of the hitch to zero cross angle, and secure with the M12 nut and M12 bolt. Also set the minimum longitudinal angle of engagement. Watch closely during the first 3-5 meters of travel as the single axle tractor and implement are operated.

If you need to deepen or raise the implement, stop the tractor and turn the crank to adjust the implement. After that you can continue driving and evaluate how the single-axle tractor works with the implement. Also, if you need to adjust the transverse angle of the grab, you need to loosen the M12 nuts and M12 bolts.

Then correct the angle in the desired direction, and tighten the nuts and bolts. Tighten all screw joints firmly before beginning the work. After the work on the ground is finished, you need to clean and lubricate the threaded joints every day. To do this, use Lithol 24.

Basic trailer assemblies

Universal design will include several auxiliary units:

  • Frame hitch, which takes the main load;
  • The body itself;
  • drawbar (hitch) designed to connect the vehicle to the trailer;
  • seating with footrest, taking into account the chosen configuration and dimensions;
  • undercarriage of the trailer (wheels);
  • the steering mechanism itself.

Among other things, it is not superfluous to provide and additional devices that will facilitate the operation: a simple folding mechanism, brakes on the trailer motorblock, additional stops, etc.

Brake system of the trailer

Before finding out how to make brakes on a single-axle tractor, it is advisable to get acquainted with such elements in more detail. They appear to be necessary for any motoblock with a trailer, because they allow you to quickly stop the moving unit, even in the presence of an impressive load.

This makes it safer to transport, which is especially important when traveling over uneven terrain with plenty of slopes. For the manufacture of such elements it is highly recommended to use ready-made parts from various cars and motor vehicles, which will greatly simplify the task. At the same time, braking systems come in different types and not all of them are suitable for use in the design of a power tiller.

Not suitable for this task and the band-type brakes, due to their low power, as well as the rapid wear and tear.

For safety, the trailer must be equipped with brakes The simplest and most effective option, which should be used as a basis for homemade brakes, are similar parts from an old motorcycle. Such spare parts are easy to find, they are affordable, which makes it possible to make brakes for a single-axle tractor without excessive costs.

If desired, you can use the parking brake from a car, which will allow you to easily stop on slopes even for a long time. However, the process of dismantling and subsequent installation of this type of brake is much more complicated, and the cost is higher, which makes this option less popular.

Operation of the system is extremely simple, because it is identical to the standard analogs used in other varieties of equipment. Braking is done by moving the lever, which pulls the cable, and for further movement it is necessary to turn the lever to the opposite position.
