Axle extender for power tillers with his hands

Wheel extensions for power tillers

Axle extensions for motor blocks allows you to expand the wheelbase. With such a part the machine becomes more stable regardless of the track width.

Extensions may be needed for such tasks:

• Performing heavy work and work on difficult soils;
• the use of machinery on uneven terrain;
• Preventing the bogging and towing of the power tiller when using complex attachments;
• provides better passability and maneuverability of the equipment;
• Iron and pneumatic wheels, grousers.

This part is selected for a particular single-axle tractor. Among the important characteristics of extensions:

• The length of the parts in the range of 200-375 mm;
• inside diameter of the planting hole. it is important that it coincides with the characteristics of the machine;
• Outer diameter of the mounting hole. responsible for the reliability of attachment of the attached equipment.

How to choose a rubber for a power tiller

The right choice of rubber for power tillers is the key to its full performance. For a correct and proper choice it is necessary to know the width of the tire. It is indicated by the first digits in the marking and is usually measured in inches, and you also need to know the seating diameter of the rim.

Its characteristics

The main characteristics of the rubber are its parameters. width, diameter, tire weight, the maximum weight of the load that it can withstand.

These characteristics and the tasks of the cultivator must be taken into account when selecting tires.

Varieties

Rubber for power tillers differs in size. In the domestic market the following are presented:

Wheels for a power tiller: review of types, how to make their own hands

Sold standard wheels are good for working on soft soils. In difficult conditions, they quickly fail, and new ones are quite expensive. Our article will tell you how to make wheels for a power tiller with their own hands.

Can wheels be mounted on a rotary cultivator?

Very often in agriculture there are serious problems with moving equipment. Cultivator wheels make it easy to get this machine to any part of the garden. Today the market offers a huge choice of wheels. However, it is possible to make them with your own hands, without spending a lot of money.

How to put Zhigul wheels

If there are old parts from Zhiguli, then there are two options for their use. The first is the creation of the ground hitch elements on the basis of discs. This procedure requires the following procedure:

• To get and clean the discs;
• In a certain order, weld the plates, which will perform the role of grousers;
• To install the grousers with the use of weights and extensions on the base.

If you use pneumatic tires from Zhiguli, it is desirable to put winter tyres on a single axle tractor, which are more aggressive and have better cross-country ability. If a single-axle tractor is used for a large area of work, you need to use a coupled version or extend the axle by installing parts from a power harvester.

Designation and types

The hub is an important component that significantly improves maneuverability of your machine, its ability to work the land and other agricultural operations.

There are 2 varieties of hubs for the wheels of a power tiller.

• Simple or Ordinary. Such parts are characterized by a simple design and quite low efficiency. they can only slightly improve the maneuverability of the machine, so they are gradually losing popularity.
• Differential. Suitable for virtually all models of power tillers, so they are also called universal. Parts with a differential are necessary for models without a wheel release and where it is difficult to turn and manoeuvre the machine. The same type of part with bearings serves to improve the maneuverability of wheeled devices.

The design of the differential hubs is simple. they consist of a retainer and one or a pair of bearings. To turn the machine, you need to remove the blocking on the required side.

Diameter and cross-sectional shape of these parts can be different:

Round hubs are available in different diameters. 24 mm, 30 mm, etc. п., Depending on the make and model of the device for which wheels (trailing wheels) they are designed.

The shape of the cross-sectional area of hexagonal wheel hub parts, as their name logically implies, is a regular hexagon. the hexagon. Their purpose is a smoother transfer of torque to the wheel pair of the power tiller and facilitate the performance of turning maneuvers.

There are 2-piece sliding hub elements. Their purpose is the same as for other similar elements, plus they allow you to adjust the track width. This is accomplished by moving the outer tube over the inner tube. Special holes are provided for fixing the required distance, into which the fasteners are inserted.

The technical data of the hub unit usually refers to the respective gearbox shaft diameters in the transmission, e.g. S24, S32, etc. д.

Also, semi-differential hub elements can be made into an almost separate species. Their function is based on the principle of transmitting the torque from the axle to the hub component by means of the projections on these elements. The wheel pair is not rigidly connected, which allows you to maneuver a U-turn without a margin of movement, practically on the spot.

Cultivator differentials

Cultivators are usually driven in a straight line, so they use a rigid drive on both wheels. However, when manoeuvring the beds, turns are often made and the rigid drive can make operation difficult. In this case, there is a need for a differential for the cultivator, which is easy to make your own hands. The differential for the power tiller has no design features compared to the differential for the power tiller, so you can use the same schemes. The simplest homemade. differential, consisting of a sleeve with a transverse axle, secured by a bolt. This design allows you to adjust the angle of rotation from 120° to 240°, which is optimal for small-sized power tillers.

How to choose a tire for your power tiller

The right choice of rubber for power tillers is the key to its full-fledged work. To make the right choice you need to know the width of the tire. It is indicated by the first digits in the marking and is usually measured in inches, and you also need to know the planting diameter of the rim.

Its characteristics

The main characteristics of rubber are its parameters. width, diameter, tire weight, the maximum weight of the load it can bear.

These characteristics and the intended use of the cultivator must be taken into account when selecting the tires.

How to install the running gear on the cultivator with your own hands

Let’s consider how to make wheels for a power tiller. Folk craftsmen offer the following self-made ones:

• For impassable terrain (swampy area, snow-covered soil), iron grundozatels will be suitable. You can use automotive, all-terrain and snowmobile products. Winter version on a single-axle tractor Neva will allow you to use the unit for transportation of snow, cleaning from the snow cover of the dacha area, transportation of goods to different distances.
• The optimal variant of modification are considered Zhigul wheels on a single-axle tractor. They have a sufficient diameter of discs, and modification is carried out with a welding machine, which is easy to use. All the more so that Zhigul tires are better suited than pneumatic wheels for a power tiller. The latter are quite difficult to find on a model that has been removed from production at the factory, and to order new ones via the Internet is expensive and impractical.
• The products themselves can also be assembled from several discs, creating a new modification with weights.
• You can put the wheels for the motor-block Neva, which are large in size, excellent cross-country ability, high service life.

The undercarriage from a Zhiguli has a number of advantages:

• Unaffected by the work it performs, so it can be used virtually all the time.
• Half-axle mounts on the inside for better maneuverability. This part should be welded to the plate, in which you need to make holes for bolts. They will be needed to connect the axle to the rails that are installed on the products.
• A special protective cap is installed on the outside.
• Good traction will provide a winter version of the rubber. You can use only tires from VAZ 2121 without cameras.

Such large wheels on a single-axle tractor with their own hands is not difficult to install, and if necessary, they can be removed and attached to a rover or small tractor, which is often used in agriculture by farmers. To improve the machine’s ride, weights or weights are installed on the undercarriage. This greatly increases the level of traction with the soil.

To work on difficult soils, it is necessary to choose products that will ensure the stability of the cultivator and its high performance.

Soil hooks, which are the special type with the maximum traction with the ground, will help. This is achieved by mounting spikes which dig deep into the soil. Similar products are made by yourself. It is possible to take the running gear from Zhiguli or Neva as a basis.

The remaking process consists of several steps:

• Attach the half axle.
• Remove the tires, since you won’t need rubber for the hooks.
• To weld on metal spikes, which will be responsible for traction with the soil. They are installed in the form of slats, which are welded on the diagonal, or in the form of spikes, arranged in several rows. The distance between the hooks should not be less than 15 cm.
• Bolt the axle to the rim.
• To change discs, for which you need to unscrew the mounts.

To create a hitch on a single axle tractor, you need parts such as:

• The old wheels from the car, it is possible without rubber;
• Angle made of steel, from which it is necessary to make the teeth of the hooks;
• bolts;
• steel thick squares;
• Metal or traction wheels are best suited for creating the grousers.

If there is a need to use not only a cultivator with an improved running gear, but a mini-tractor at the cottage, then you need to create a special frame. For this purpose, a larger product is installed on the power tiller, and a support wheel for the power tiller is put. At home, you can create an economical version of a small all-terrain vehicle, on which there will be products from the VAZ car or a pair of twin Zhigulev products with grototraps. Such a machine will be easy to drive off-road, work in the field, in the swamps. At the same time, the undercarriage of power tillers-vehicles should be equipped not only with large wide products, but also with special trim. The frame of the equipment must be raised, so that the motocultivator was convenient to move. That’s why it’s worth installing big wheels.
