Agricultural Gearbox
The agricultural gearbox is the main 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 operating 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 are positioned 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 usually adopted middle gear transmission program, 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 dependable and the overall performance is well. So it can be utilized on dried out and paddy field. It can reduce the time, laboring, and cost, 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 main one with the input shaft, has the fewer quantity of teeth (pinion), therefore the output shaft rotates slower than the input shaft.
It is called an increaser when the input shaft is mounted on the apparatus with the larger number 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 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 versions with parallel shafts with two gearboxes.
Speed change
in addition to the primary couple of gears and relevant shafts, the gearboxes could also have other gears with a different amount of teeth. The gear shift of the primary pair of gears with the secondary types enables different speeds. The manual switch of the secondary equipment pair with gears with different quantity of teeth gearbox for agricultural machinery allows modifications to the output rotation speed.
