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 may also be transmitted to the gearbox by hydraulic motors or belt pulleys, in addition to chain gears.
Agricultural gearboxes will have 1 input shaft and at least one particular output shaft. If these shafts sit at 90° to one another, the gearbox is an ORTHOGONAL ANGLE gearbox or even more frequently called a right-angle gearbox.

rotary tiller gearbox is usually adopted middle gear transmission program, mounted with the tractor of 12-80HP. Tractor wheel tracks are totally covered after tillage as the operating width is a lot wider. The quality is dependable and the efficiency is well. So it can be used on dry and paddy field. It could reduce the time, laboring, and cost, etc. during operation

Increasers and Reducers
When the gearboxes have the two gears with different numbers of teeth.
The gearbox is a reducer when the driving gear, i.e. the one with the input shaft, has the fewer amount of teeth (pinion), therefore the result shaft rotates slower compared to the input shaft.
It is named an increaser when the insight shaft is mounted on the gear with the larger number of teeth (crown), hence the result shaft rotates faster compared to the input shaft.
Right-angle gearboxes, distributors or rotational reverse gearboxes
When the gearboxes have gears with the same number of teeth.
The gearbox is called right-angle when it only has two shafts (input and output),
whereas it really is called a distributor when there are at least two output shafts.
It really is called a rotational invert 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 additional gears with a different amount of teeth. The gear shift of the primary pair of gears with the secondary ones allows different speeds. The manual switch of the secondary gear pair with gears with different quantity of teeth allows adjustments to the output rotation speed.
