Tractor Parts

The tractor drawbar is used to pull various implements. Some tractors have a drawbar which can be attached to the hydraulic linkage. It is not used for heavy implements.

Some tractors have special automatic devices which enable the tractor driver to lift an implement without leaving his seat. These devices are operated hydraulically. In this way much of the weight of the implement is carried on the tractor providing better wheel grip. If an implement is mounted on a hydraulic lift system its weight can be used to increase the pulling power of the tractor: the three-point linkage system transmits much of the weight of the implement on to the tractor. So one can design lighter implements which need no wheels or heavy drawbars. Mounted implements are easily transported. Hydraulically operated implements can also be attached in front of the tractor.

Using the hydraulic system one can lower of lift the mounted implements. The hydraulic system provides the power for hydraulic motors which are used to drive different machines.

The power-take-off shaft is the driving fоrсе for different implements. It can drive irrigation pumps and cultivation machinery. It can provide for the farm when there is a cut in the electricity supply. Some stationary machines are belt driven. Tractors can provide the driving power for this too. Some tractors have a belt pulley mounted on the gear-box and driven by it. Other tractors can have a pulley connected with the power-take-off shaft.
