Agricultural Gearbox
The agricultural gearbox is the main mechanical element of the kinematic chain of agricultural machines. It is normally powered 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 1 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-position gearbox.
rotary tiller gearbox is usually adopted middle gear transmission system, mounted with the tractor of 12-80HP. Tractor wheel tracks are totally covered after tillage as the working width is a lot wider. The quality is dependable and the efficiency is well. So that it can be utilized on dry and paddy field. It can decrease the time, laboring, and price, 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.electronic. the one with the input shaft, has the fewer number of teeth (pinion), hence the result shaft rotates slower than the input shaft.
It is named an increaser when the insight shaft is mounted on the gear with the larger quantity of teeth (crown), 
thus the result 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 teeth.
The gearbox is known as 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 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 pair of gears and relevant shafts, the gearboxes could also have other gears with a different amount of teeth. The apparatus shift of the main pair of gears with the secondary types allows different speeds. The manual switch of the secondary equipment set with gears with different quantity of teeth allows gearbox for agricultural machinery modifications to the output rotation speed.
