Agricultural Gearbox
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 may also be transmitted to the gearbox by hydraulic motors or belt pulleys, furthermore to chain gears.
Agricultural gearboxes always have 1 input shaft and at least one particular output shaft. If these shafts sit 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 gearbox for agricultural machinery program, mounted with the tractor of 12-80HP. Tractor wheel tracks are totally covered after tillage as the operating width is much wider. The quality is dependable and the functionality is well. So it can be used 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.e. the main one with the insight shaft, gets the fewer amount of teeth (pinion), hence the output 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), therefore the output 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 reverse gearbox and parallel offset in the versions with parallel shafts with two gearboxes.
Speed change
in addition to the primary couple of gears and relevant shafts, the gearboxes may also have additional gears with a different amount of teeth. The gear shift of the primary couple of gears with the secondary ones allows different speeds. The manual switch of the secondary equipment set with gears with different amount of teeth allows adjustments to the result rotation speed.
