A mini-tractor is an extremely valuable type of agricultural machinery. But for it to work fully, it is required to use specialized propulsors. If this rule is not observed, it is impossible to guarantee the normal operation of the mechanism.
Key selection criteria
When choosing wheels for a mini-tractor, it is imperative to consider the recommendations that the manufacturer gives. It is important that you read the instructions carefully before purchasing. But if the unit is made with your own hands (and this happens quite often), you can do otherwise.
First of all, pay attention to the width of the tread. Its size should be as large as possible if you plan to work in the spring.
Very narrow tires on wet, loose ground will skid, and the overall speed will decrease markedly.
It should also be taken into account which soil is to be cultivated. On a water-saturated, hard-to-treat area, one wheel is needed. If the ground is soft enough and crumpled easily, completely different propulsors are used. An important moment when choosing rubber for a mini-tractor or walk-behind tractor is the level of carrying capacity.
Often miniature tractors equip:
- front loaders;
- mounted excavators.
Naturally, in this case, use the strongest tires. After all, the total load on them is growing significantly. Most consumers “shoe” their cars with rubber marked as R14 or R16.
However, we must also look at the tread pattern. Within even one standard size, both summer and winter options can be present - they can be distinguished by external signs.
Wheels for agricultural vehicles marked as R13 or R22 are of considerable popularity . But before buying, you still need to check what the track of specific movers is. It must strictly coincide with the same parameter for the tractor itself. However, a considerable part of manufacturers does not indicate such information. For some models, the track is set rigidly, for others it is subject to free adjustment.
Quite often, wheels with a diameter of 16 inches are used. They allow you to provide quick processing of any land, including harvesting and planting root crops.
If thrusters of 13 inches or 14 inches are used, they should have a characteristic "Christmas tree" tread. When replacing previously installed tires, do not reduce the gauge. Otherwise, the capacity of the device will be drastically reduced.
Information about the permissible load on each wheel is indicated in the instructions under the name of “load index” or “ply standard”.
Tires of "diagonal" design are intended for machines used for a relatively short time. The small price of such a product turns out to be shorter than the more expensive varieties.
If you want to ride longer or increase the speed of movement on hard surfaces, radial tires are preferred.
Note: you should not combine rubber from different manufacturers on the same axis. Even when the main parameters mentioned in the descriptions are the same, problems can still appear.
It is very easy to pick up wheels, for example, according to the 6x14 formula. However, situations often arise where the tire size markings have faded over time. Then you need to set its dimensions along the width of the tread (by measuring the distance between the sidewalls). Dividing the resulting figure by 2.54, get the desired value in inches. Then restore the so-called landing diameter.
Having measured the cross section of the rim, it is taken into account that it shows the size of the inner hole of the tire. After measurement, the indicator is also converted to inches.
In many cases, it is necessary to supplement the wheels of the mini-tractor with chains that reduce the level of sliding. They are oriented exactly along the axis of each mover. Chains need to be selected exactly matching the radius of the wheels.
As for the lawn tires for mini tractors, everything is simple - they should be used only where it is very important to reduce pressure on the ground. Such tires are in demand on golf and soccer fields.
An important feature is the low severity of the tread. When the clearance created by typical wheels is not enough, it is additionally increased using spacers. This name was given to the special flanges that separate the discs from the hubs.
If the miniature tractor has four-wheel drive, the rubber should be identical on all axles . In this case, the specificity of the alignment and convergence is necessarily taken into account. Of course, you should choose the products of well-known companies in order to get the best result.
Tires for trailers for mini-tractors should vary in diameter. But buying products from different manufacturers is not recommended.
