gearbox for agricultural machinery agricultural Gearbox
The agricultural gearbox is the primary 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, furthermore to chain gears.
Agricultural gearboxes will have a single input shaft and at least a single output shaft. If these shafts are positioned at 90° to one another, the gearbox is an ORTHOGONAL ANGLE gearbox or more commonly called a right-angle gearbox.
rotary tiller gearbox is usually adopted middle gear transmission system, mounted with the tractor of 12-80HP. Tractor wheel tracks are totally protected after tillage as the functioning width is much wider. The quality is dependable and the performance is well. So that it can be used on dried out and paddy field. It can reduce the time, laboring, and price, etc. during operation
Increasers and Reducers
When the gearboxes have both gears with different numbers of teeth.
The gearbox is a reducer when the driving gear, i.e. the main one with the input shaft, has the fewer number of teeth (pinion), therefore the result shaft rotates slower than the input shaft.
It is named an increaser when the insight shaft is mounted on the apparatus with the larger number of teeth (crown), thus the output shaft rotates faster than the input shaft.
Right-angle gearboxes, distributors or rotational reverse gearboxes
When the gearboxes 
have gears with the same number of tooth.
The gearbox is known as right-angle when it only has two shafts (input and output),
whereas it really is called a distributor whenever there are at least two output shafts.
It really is called a rotational reverse gearbox and parallel offset in the versions with parallel shafts with two gearboxes.
Speed change
in addition to the main couple of gears and relevant shafts, the gearboxes could also have other gears with a different number of teeth. The apparatus shift of the primary couple of gears with the secondary types allows different speeds. The manual switch of the secondary equipment pair with gears with different quantity of teeth allows modifications to the result rotation speed.
