Agricultural Gearbox
The agricultural gearbox is the primary mechanical element 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 working 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 each other, the gearbox can be an ORTHOGONAL ANGLE gearbox or more frequently called a right-angle gearbox.
rotary tiller gearbox is adopted middle equipment transmission program, mounted with the tractor of 12-80HP. Tractor wheel tracks are completely protected after tillage as the working width is a lot wider. The product quality is reliable and the performance is well. So that it can be used on dry and paddy field. It can reduce the time, laboring, and price, etc. during gearbox for agricultural machinery operation
Increasers and Reducers
When the gearboxes have the two gears with different amounts of teeth.
The gearbox is a reducer when the driving gear, i.e. the main 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 amount of teeth (crown), thus 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 tooth.
The gearbox is called 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 is called a rotational invert gearbox and parallel offset in the variations with parallel shafts with two gearboxes.
Speed change
in addition to the primary pair of gears and relevant shafts, the gearboxes may also have various other gears with a different quantity of teeth. The gear shift of the primary pair of gears with the secondary ones enables different speeds. The manual switch of the secondary equipment pair with gears with different quantity of teeth allows adjustments to the output rotation speed.
