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 working torque can also be transmitted to the gearbox by hydraulic motors or belt pulleys, in addition to chain gears.
Agricultural gearboxes gearbox for agricultural machinery always have a single input shaft and at least one output shaft. If these shafts sit at 90° to one another, the gearbox is 
an ORTHOGONAL ANGLE gearbox or more frequently called a right-angle gearbox.
rotary tiller gearbox is adopted middle gear transmission system, mounted with the tractor of 12-80HP. Tractor wheel tracks are completely protected after tillage as the functioning width is a lot wider. The product quality is dependable and the efficiency is well. So it can be used on dry and paddy field. It can reduce the time, laboring, and price, etc. during operation
Increasers and Reducers
When the gearboxes have the two gears with different numbers of teeth.
The gearbox is a reducer when the driving gear, i.electronic. the main one with the input shaft, has the fewer number of teeth (pinion), hence the result shaft rotates slower than the input shaft.
It is called an increaser when the insight shaft is mounted on the gear with the larger quantity of teeth (crown), therefore 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 teeth.
The gearbox is known as 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 invert gearbox and parallel offset in the variations 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 pair of gears with the secondary ones allows different speeds. The manual change of the secondary equipment pair with gears with different number of teeth allows modifications to the result rotation speed.
