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 operating torque can also be transmitted to the gearbox by hydraulic gearbox for agricultural machinery motors or belt pulleys, furthermore to chain gears.
Agricultural gearboxes will have one input shaft and at least a single output shaft. If these shafts are positioned at 90° to one another, the gearbox is an ORTHOGONAL ANGLE gearbox or 
more frequently called a right-angle gearbox.
rotary tiller gearbox is definitely adopted middle equipment transmission system, 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 that it can be utilized on dried out and paddy field. It can decrease the time, laboring, and price, etc. during operation
Increasers and Reducers
When the gearboxes have both gears with different numbers of teeth.
The gearbox is a reducer when the driving gear, i.e. the main one with the insight shaft, has the fewer quantity of teeth (pinion), hence the output shaft rotates slower compared to the input shaft.
It is named an increaser when the input shaft is mounted on the gear with the larger quantity of teeth (crown), therefore 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 the 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 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 various other gears with a different number of teeth. The apparatus shift of the primary couple of gears with the secondary types allows different speeds. The manual switch of the secondary equipment set with gears with different quantity of teeth allows adjustments to the result rotation speed.
