Description

The agricultural gearbox is the main mechanical component of the kinematic chain of agricultural machines. It is normally driven by the tractor power take-off via the PTO shaft and the gearbox drives. The operating torque can also be transmitted to the gearbox by hydraulic motors or belt pulleys, in addition to chain gears.

Agricultural gearboxes always have one input shaft and at least one output shaft. If these shafts are positioned at 90° to each other, the gearbox is an ORTHOGONAL ANGLE gearbox or more commonly called a right-angle gearbox.

If the input and output shafts are placed parallel to each other, the agricultural gearbox is known as PARALLEL SHAFT gearbox.
