Agricultural Gearbox
The agricultural gearbox is the primary 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 always have one input shaft and at least 1 gearbox for agricultural machinery output shaft. If these shafts sit at 90° to each other, the gearbox can be an ORTHOGONAL ANGLE gearbox or more generally called 
a right-position gearbox.
rotary tiller gearbox is certainly adopted middle gear transmission system, mounted with the tractor of 12-80HP. Tractor wheel tracks are totally covered after tillage as the functioning width is a lot wider. The quality is reliable and the overall performance is well. So that it can be utilized on dried out and paddy field. It could decrease 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 insight shaft, gets the fewer amount of teeth (pinion), hence the result shaft rotates slower than the input shaft.
It is named an increaser when the input shaft is mounted on the gear with the larger amount of teeth (crown), hence the output shaft rotates faster compared to the input shaft.
Right-angle gearboxes, distributors or rotational invert 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 really is called a distributor when there are at least two output shafts.
It really is called a rotational invert gearbox and parallel offset in the versions with parallel shafts with two gearboxes.
Speed change
in addition to the main pair of gears and relevant shafts, the gearboxes could also have various other gears with a different amount of teeth. The apparatus shift of the main couple of gears with the secondary types enables different speeds. The manual switch of the secondary equipment set with gears with different amount of teeth allows adjustments to the result rotation speed.
