Tractor Bearings

There is a very common misconception that hydraulic system on old tractors have to work in conjunction with chain and pinion or screw operated pinion drives. hydraulic system refers to a combination of a control valve which can be either wound or un-wound, a pinion or chain, and a hydraulic driven gear ration. The fact is that these hydraulic systems and the associated gear ration can be changed easily without changing the drive system itself and the benefits of doing so far outweigh any disadvantages. In addition to all these benefits, the hydraulic system is also readily available and easy to use and can be integrated into new drive train units with minimal cost. Changing your hydraulic system alone will cost you more than replacing the entire tractor.

Bearings, as their name suggests, are used to counterbalance the load by counteracting the force applied to it. The most common types of bearings are a front wheel reduction gear, front wheel drive, and a double bevel pinion or two pinion drives. A front wheel reduction gear has a bearing which is directly attached to the track and acts to reduce the weight of the whole tractor. On the other hand, a front wheel drive has a single beveled pinion or two pinion drives and acts to increase the weight of the whole tractor. A double bevel gear has a center pinion and thus has two beveled bearings and a front wheel reduction gear.

In order to understand the relationship between all of these elements, it helps to first know a little bit about the different designs available. You will find the following designs: Drive Shafts, Drive Belts, Box Beams, and Cylinder Beams. Bearings can be made from numerous materials. The most common ones are aluminum, cast iron, steel, bronze, and fiberglass.
