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, furthermore to chain gears.
Agricultural gearboxes always have one input shaft and at least a single output shaft. If these shafts sit at 90° to each other, the gearbox can be an ORTHOGONAL ANGLE gearbox or even more typically called a right-position gearbox.

rotary tiller gearbox can be adopted middle equipment 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 dependable and the performance is well. So it can be used on dry and paddy field. It could reduce the time, gearbox for agricultural machinery laboring, and price, 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.electronic. the main one with the input shaft, has the fewer number of teeth (pinion), therefore 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), hence the result shaft rotates faster than 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 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 primary couple of gears and relevant shafts, the gearboxes could also have various other gears with a different amount of teeth. The gear shift of the main pair of gears with the secondary ones enables different speeds. The manual change of the secondary equipment pair with gears with different number of teeth allows modifications to the output rotation speed.
