Options for drawings of a wheel structure for a walk-behind tractor
Factory complete sets of wheels for a motor cultivator are classified according to the number of axles, as well as the principle of traction. Manufacturers make home mini tractors, the design of which assumes the movement of the unit due to:
- two wheelsets;
- paired wheeled structure on one axle;
- one driving wheel;
- on three wheels.
One-wheel mechanisms are more often equipped with additional devices on the axle, which also serve as a support for the structure. Analyze the model of your home cultivator to improve its functionality. Find a durable, reliable material or a suitable base for making your homemade undercarriage parts.
Four-wheel option
Agricultural small tractors on four wheels are a miniature of a similar vehicle without a cab. The configuration of the models allows the user to move around on the walk-behind tractor.
To upgrade the factory configuration, you can replace only the drive pair or change all the discs. Choose one of the options to improve the performance of your home farm equipment:
- equipping factory tires with additional treads;
- setting on wheels of new rubber with a textured pattern;
- installation of wheelsets of different radii on the axle - larger under the mechanisms, smaller under the driven part;
- mounting wheels from the car.
Important!
Wheel design is an important stage in the improvement of a walk-behind tractor, at which it is required to make accurate calculations of the optimal dimensions, the location of the elements, the places for drilling the fasteners.
Four-wheeled motoblocks are classified as heavyweight models. A number of machines are configured with non-removable wheel elements. Before reworking the minitractor, make a drawing according to which you plan to improve.
On one wheel pair
Two-wheel motor-cultivators are equipped with one axle with a pair of wheel elements. The platform with the motor installed is operated by the user using the handles. Setting a passable wheelset will solve the problem with:
- slippage;
- slipping;
- filling with earth a little pronounced tread pattern;
- poor handling;
- insufficient plowing depth, etc.
Draw a sketch of one element on paper yourself or complete the drawing in a computer program. In the figure, indicate the diameter of the disc, the location of the holes for the axis, fastenings, and their dimensions.
With one drive wheel
One-wheel cultivators are devices in the form of a wheel element in a tire with a pronounced tread. The speed of work and the coefficient of efficiency when performing farm work depends on the permeability of the disk.
When preparing a drawing for replacing the drive wheel, use the recommendations:
- select the diameter of the wheel element, the same as in the factory;
- choose materials with a lot of weight when making your own wheel;
- replace the rubber with a more textured and wider one.
A walk-behind tractor on one wheel is controlled by manual manipulation. It will be easier for you to drive a structure with a wide wheel and strong tread.
Three-wheeled models
On small agricultural tractors for cultivating a summer cottage with three wheels, the front element performs the function of following a given trajectory. The rear wheelset is supplied with torque from the engine of the unit.In most models, the front undercarriage is made with a larger diameter.
To design wheel replacement on a single-axle small tractor, use the recommendations:
- calculate the same rim and tire radius as provided by the factory. Placing a smaller or larger wheel in diameter will make the mechanisms work incorrectly;
- make identical wheel elements. Replacing with wheels with different tread patterns or different weights will complicate the use of a mini tractor.
When making a drawing with your own hands, take as a basis the model designed by the manufacturer. Consider the full radius of the elements. You can design a disc with a smaller diameter, but install thick rubber on it, and vice versa.
Wheels for the Neva walk-behind tractor
Motoblocks "Neva" are one of the most widespread and rather multifunctional types. Regardless of what kind of work is performed on them, work on this walk-behind tractor is impossible without wheels and attachments. The choice for this model is quite extensive, given the versatility of this unit and the truly popular love for it.
"Neva"
Allocate wheels of the following types for the "Neva" walk-behind tractor:
- Pneumatic wheels, they are equipped with a motorcycle tire, a camera, a motor-cultivator wheel hub and a disc. Pneumatic wheels are installed on the gearbox shaft in such a way that the tops of the studs are located in the direction of travel.
- Metal, or lugs, are used to increase traction due to more traction on the ground. There are wide, tall and narrow types of metal wheels. In addition, metal wheels with blades, spikes and other devices are used for various types of soil cultivation.
In general, the wheels installed on the Neva can be classified as follows:
- transport 4 0x8 - used for transporting goods to walk-behind trailers, installing them on trailers, moving walk-behind trailers on roads. They differ in their relatively small diameter and tire pressure, their width is about 4 inches;
- track widening kits, consisting of two stoppers and several extensions, their functionality is track widening. It is optimal to purchase a set of extension cords that allow you to install wide wheels on the walk-behind tractor;
- draft 16x6 50 8, installed as a set, used for draft work. The tires are tubeless, so they do not fail due to pumping, they have an outer diameter of about 16 inches and an operating pressure of four atmospheres;
- lugs KUM-540, 680 for hilling, lugs N for plowing. Ideal for traversing soft and difficult soils. It is also recommended to additionally equip them with weighting materials.
On a note. In addition, self-made lugs are installed on Neva motor-cultivators, which are made for specific tasks and needs of the owner of this equipment. As pneumatic wheels can be installed ideally suited to the "Neva" from the cars "Zhiguli", "Oka", "Niva" and "Moskvich".
The owners of the "Neva" themselves are enthusiastic about such alterations, since they are often dissatisfied with the driving performance of the wheels from the factory complete set.
