Agricultural Gearbox
The agricultural gearbox is the primary mechanical element of the kinematic chain of agricultural machines. It is normally powered by the tractor power gearbox for agricultural machinery 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, furthermore to chain gears.
Agricultural gearboxes always 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 typically called a right-angle gearbox.
rotary tiller gearbox is certainly adopted middle equipment transmission program, 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 functionality is well. So that it can be used on dry 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.electronic. the one with the insight shaft, gets the fewer quantity of teeth (pinion), hence the result shaft rotates slower than the input shaft.
It is called an increaser when the input shaft is mounted on the gear with the larger number of teeth (crown), thus the result 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 tooth.
The gearbox is called 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 main couple of gears and relevant shafts, the gearboxes may also have additional gears with a different amount of teeth. The gear shift of the main pair of gears with the secondary types enables different speeds. The manual change of the secondary gear set with gears with different amount of teeth allows modifications to the result rotation speed.
