DIY adapter for a motor cultivator

Working with adapter design

Now starts working with the adapter. To do this, we perform the following actions:

  • A piece of 300 mm pipe needs to be welded to the center frame. this will be a stand for the driver’s seat.
  • From above, perpendicular to this stand, in the same way, weld 2 pieces of pipe. This is required so that the seat does not come off during operation and is more stable during shaking during operation. The seat can be ready, or you can make it yourself from a piece of plywood and foam rubber, this is at the discretion of the master.
  • We attach the seat to the transverse pieces of the pipe, which we weld to the stand itself, as well as to the stand under the seat. We use ordinary bolts as a fastener.
  • We weld the coupling mechanism with the tiller in front, after which the work can be considered finished.

As you can see, this is a fairly simple matter. The main difficulty lies only in the need to have at least initial skills in working with a welding machine, since there is simply no other method of connecting each component.

Adapter manufacturing at home

The first thing is to draw up a kinematic diagram.

To keep the structure in balance, as well as to prevent other overloads. The kinematic diagram can be created by hand, or bought ready-made.

The second is to make the basic details.

In the process of making and assembling the frame, you can make a fork and a bushing, thanks to which the trailer turns freely. The body is made from a sheet of steel with a side height of at least 30 cm.

The simplest option for the production of a coupling assembly for the entire structure is a pin, 15 cm long.It is stuck into the drawbar (i.e. its hole) with a U-shaped motoblock hitch.

It attaches directly to the adapter beam (ridge frame), 80 cm from the front-most edge. Fixing is done with bolts. And that’s all, you can check the operation of the device and start it up.!

Varieties

The design of the fixture differs in the connection method:

  • Strong attachment to the tiller. there is a separate steering wheel. Steering wheels can be in front and rear.
  • Movable joint. there is a change in the angle between the tiller and the trailer. Turning requires a lot of effort due to the movable joint.

With regard to driving wheels, they are divided into:

  • Front. the hitch mechanism is located at the back;
  • Rear. hitch mechanism located in front.

You can also divide these devices by use into simple and universal. Universal are used, in addition to the main purpose, for the movement of goods.
In relation to the power of the tiller model, devices with a long or short drawbar are used. If there is a low power, it is better to attach a short drawbar. The heavy tiller adapter has a large drawbar.

Maintenance of the structure

In order for the mini tractor to serve for many years, it is recommended to observe the operating rules, which are as follows:

  • monitor fuel quality.
  • control the direction of the knives when
    installing cultivation sheds.
  • shut off the air supply when starting the chilled unit into operation.
  • limit the speed when the engine is warming up.

To facilitate the laborious work of cultivating agricultural land, mowing the lawn or removing snow, the tiller can be controlled using an adapter.

The purpose of the adapter

Here, I think everything is clear, there is a fairly large amount of work on the ground, which is easier, faster and more convenient to do with an adapter. And working with such attachments as a rotary tiller, in general, it is safer.

We make an adapter for the tiller with our own hands

At the moment, there are several types of adapter, as a rule, their designs are similar, and are, attached to the rear of the tiller, adapt with a comfortable seat.

The adapter is made of a square metal profile, from 160 to 180 cm long. Across this profile, another one is welded, 50-60 cm in size, depending on which track you need, (wheel stands are attached to it). The height of the struts to the wheel axle from the top to the adapter wheel axle can be from 25 to 40 cm, depending on the design.

Further, braces are welded to the main metal profile and wheel hubs, they also serve as stiffeners. Their length depends on the angle of inclination relative to the entire structure and other parameters. Then, the frame structure is calculated and welded in the same way, to which the attachment will be attached. Side rails of this design are bolted to the wheel struts.

After that, a control lever is welded to the main frame, which has three knees, sizes 35, 55, 20 cm.To increase the applied force, another lever is attached to the lever, but already with dimensions of 80 cm.

Adapter seat, mounted on a support welded to the central metal profile. As you can see, making an adapter to the tiller with your own hands is not so difficult.

Tiller adapter design diagram

The adapter for the tiller is a kind of towing device made on the frame and having two wheels. Structurally, adapters are divided into several types, in terms of simple, they can be simple and more complex. The main types are considered universal, these are those that are able to transport goods and perform soil cultivation, and simple ones, capable of performing only soil cultivation.

For tillers of different power, different adapters are used, for a low power one, an adapter with a short drawbar is installed, for a powerful one with a long one. Also, universal adapters are equipped with additional functionality, an increase in track, lifting attachments, etc.

Drawings of the main units

  • Clutch mechanism. Represents a welded structure inserted into a main frame and bolted to it. Consists of welded on each other two pieces of square pipe and a piece of ordinary “water” pipe with a caliber of 1 inch.

In the latter, a stem not fully clamped by a bolt is inserted with a homemade tee welded on. The stem is lubricated with grease or grease and allows the tee to rotate along the axis to provide a rolling effect when moving on bumpy soil.

Construction of two pipe sections, welded perpendicularly. The horizontal section is inserted into the fixing pipe and fixed with a bolt. An axle with a wheel is fixed on a vertical piece (on bearings).

The rest of the nodes are not so essential, and we will not consider them.

Tiller device

By its design, the 4 × 4 adapter, which is intended for the Neva Tiller, is a rather simple device. It includes several fundamental parts:

  • frame structure, on which other accessories can be installed;
  • driver’s seat;
  • wheelbase including wheel axle;
  • tiller connection mechanism, including.

In other words, the adapter is an ordinary cart with a seat that connects to the tiller.

Tillers come in different brands and designs. The Russian user knows, for example: Cayman, Foreman, Viking, Crossser, Texas, Patriot and others. After hitching the tiller and the adapter, the resulting device can be compared in functionality with a mini-tractor, however, such a comparison is somewhat arbitrary, since the power will remain the same, because the engine still remains alone, and it is from the tiller.

over, you can attach auxiliary attachments to the adapter, which will further expand the potential list of works. Some types of adapters are equipped with special sections where you can place any cargo. There are also models that are equipped with a lifting arm, which greatly simplifies the work with the additional device.

Flexible joint adapter

With a movable joint, the angle relative to the vertical axis between the adapter and the tiller changes. It is much easier to make such a trailer, but it will require more effort when making a turn. However, this type of adapter is inferior in geometry: the turning radius, as well as its angle, is much larger.

Front adapter

Structurally, it is similar to the previous type of adapter, but at the same time it has a hitch mechanism at the back. This means that we get a full-weight front adapter for the Neva brand tiller. The presented design is completely disassembled, which greatly simplifies its subsequent transportation. Naturally, the cost of any additions to the unit is formed separately.

Front adapter specifications:

  • length. 190 cm;
  • width. 81 cm;
  • height. 140 cm;
  • ground clearance. 30 cm;
  • wheel track. 75 cm;
  • speed indicators. approx. 10 km / h;
  • total weight. 65 kg.
