Agricultural Gearbox
The agricultural gearbox is the main mechanical component 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 working torque may also be transmitted to the gearbox by hydraulic motors or belt pulleys, in addition to chain gears.
Agricultural gearboxes always have one input shaft and at least a single output shaft. If these shafts sit at 90° to one another, the gearbox can be an ORTHOGONAL ANGLE gearbox or even more generally called a right-angle gearbox.
rotary tiller gearbox can be adopted middle gear transmission program, mounted with the tractor of 12-80HP. Tractor wheel tracks are completely protected after tillage as the functioning width is much wider. The product quality is reliable and the functionality is well. So that it can be used on dry and paddy field. It could 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 reducer when the driving gear, i.e. the main one with the insight 
shaft, has the fewer quantity of teeth (pinion), thus the output shaft rotates slower compared to the input shaft.
It is named an increaser when the insight shaft is mounted on the apparatus with the larger number of teeth (crown), gearbox for agricultural machinery therefore the output shaft rotates faster than 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 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 really is called a rotational reverse gearbox and parallel offset in the variations with parallel shafts with two gearboxes.
Speed change
in addition to the main couple 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 couple of gears with the secondary ones enables different speeds. The manual change of the secondary gear pair with gears with different amount of teeth allows modifications to the result rotation speed.
