Agricultural Gearbox
The agricultural gearbox is the main mechanical element of the kinematic chain of agricultural machines. It really is normally powered 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 one input shaft and at least one particular output shaft. If these shafts sit at 90° to each other, the gearbox can be an ORTHOGONAL ANGLE gearbox or even more typically 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 covered after tillage as the working width is much wider. The quality is dependable and the functionality is well. So 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 gearbox for agricultural machinery reducer when the driving gear, i.e. the 
main one with the input shaft, gets the fewer quantity 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 amount 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 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 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 pair with gears with different amount of teeth allows modifications to the result rotation speed.
