Agricultural Gearbox
The agricultural gearbox is the primary mechanical component of the kinematic chain of agricultural machines. It is normally powered 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, in addition to chain gears.
Agricultural gearboxes always have a single input shaft and at least 1 output shaft. If these shafts sit at 90° to one another, the gearbox is an ORTHOGONAL ANGLE gearbox or more typically called a right-angle gearbox.

rotary tiller gearbox is usually adopted middle gear transmission program, mounted with the tractor of 12-80HP. Tractor wheel tracks are totally covered after tillage as the operating width is much wider. The quality is dependable and the efficiency is well. So that it can be used on dry and paddy field. It can reduce the time, laboring, and cost, etc. during 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, gets the fewer number of teeth (pinion), hence the output shaft rotates slower than the input shaft.
It is called an increaser when the input shaft is mounted on the gear with the larger quantity of teeth (crown), hence the output 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 tooth.
The gearbox is called 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 quantity of teeth. The apparatus shift of the main couple of gears with the secondary ones enables different speeds. The manual switch of the secondary equipment pair with gears with different amount of teeth allows modifications to the result rotation speed.
