Agricultural Gearbox
The agricultural gearbox is the primary 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 working torque can also be transmitted to the gearbox by hydraulic motors or belt pulleys, furthermore to chain gears.
Agricultural gearboxes always have a single input shaft and at least one particular output shaft. If these shafts are positioned at 90° to one another, the gearbox is an ORTHOGONAL ANGLE gearbox or even more typically called a right-position gearbox.
rotary tiller gearbox is certainly adopted middle gear transmission program, mounted with the tractor of 12-80HP. Tractor wheel tracks are completely covered after tillage as the working width is much wider. The quality is reliable and the overall performance is well. So that it can be used on dried out and paddy field. It could decrease the time, laboring, and price, etc. during operation
Increasers and Reducers
When the gearboxes have both gears with different amounts of teeth.
The gearbox is a reducer when the driving gear, i.e. the one with the input shaft, has the fewer number of teeth (pinion), therefore the result shaft rotates slower than the input shaft.
It is called an increaser when the insight shaft is mounted on the apparatus with the larger quantity of teeth (crown), therefore the result 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 tooth.
The gearbox is called right-angle when it only has two shafts (input and output),
whereas it is called a distributor when there are at least two output shafts.
It is called a rotational reverse gearbox and parallel offset in the gearbox for agricultural machinery versions with parallel shafts with two gearboxes.
Speed change
in addition to the main pair of gears and relevant shafts, the gearboxes may also have other gears with a different number of teeth. The gear shift of the primary pair of gears with the secondary types enables different speeds. The manual switch of the secondary gear pair with gears with different 
number of teeth allows modifications to the output rotation speed.
