Gearboxes
The gearbox is the principal mechanical component of the kinematic chain of agricultural machines. It is normally pushed by the tractor electrical power get-off through the PTO shaft and the gearbox drives. The running torque can also be transmitted to the gearbox by hydraulic motors or belt pulleys, in addition to chain gears.
Gearboxes constantly have 1 enter shaft and at the very least a single output shaft. If these shafts are positioned at 90°
