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 will have a single input shaft and at least one output shaft. If these shafts sit at 90° to each other, the gearbox can be an ORTHOGONAL ANGLE gearbox or even more commonly called a right-angle gearbox.
rotary tiller gearbox is certainly adopted middle gear transmission system, mounted with the tractor of 12-80HP. Tractor wheel tracks are completely protected after tillage as the operating width is much wider. The quality is reliable and the performance 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 
gearbox for agricultural machinery different amounts 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), therefore the result shaft rotates slower compared to the input shaft.
It is called an increaser when the input shaft is mounted on the gear with the larger number of teeth (crown), thus the output shaft rotates faster compared to the input shaft.
Right-angle gearboxes, distributors or rotational invert 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 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 primary couple of gears and relevant shafts, the gearboxes may also have additional gears with a different number of teeth. The gear shift of the main couple of gears with the secondary ones enables different speeds. The manual switch of the secondary equipment set with gears with different amount of teeth allows adjustments to the result rotation speed.
