Agricultural Gearbox
The agricultural gearbox is the primary 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 operating torque may 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 output shaft. If these shafts are positioned at 90° to each other, the gearbox can be an ORTHOGONAL ANGLE gearbox or more frequently called a right-position gearbox.
rotary tiller gearbox is usually adopted gearbox for agricultural machinery middle gear transmission system, mounted with the tractor of 12-80HP. Tractor wheel tracks are totally covered after tillage as the working width is much wider. The quality is dependable and the efficiency is well. So that it can be used on dried out and paddy field. It could decrease 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 one with the input shaft, has the fewer quantity of teeth (pinion), hence the output shaft rotates slower than the input shaft.
It is called an increaser when the insight shaft is mounted on the apparatus with the larger number of teeth (crown), thus the result 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 known as 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 various other gears with a different number of teeth. The gear shift of the main pair of gears with the secondary types allows different speeds. The manual 
change of the secondary equipment pair with gears with different quantity of teeth allows adjustments to the output rotation speed.
