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 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 1 input shaft and at least a single output shaft. If these shafts sit at 90° to one another, the gearbox is an ORTHOGONAL ANGLE gearbox or more generally called a right-position gearbox.
rotary tiller gearbox can be adopted middle equipment transmission program, mounted with the tractor of 12-80HP. Tractor wheel tracks are totally covered after tillage as the operating width is much wider. The quality is reliable and the overall performance is well. So it can be utilized on dry and paddy field. It can reduce the time, laboring, and price, 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 main one with the insight shaft, has the fewer number of teeth (pinion), therefore the output shaft rotates slower than the input shaft.
It is named an increaser when the input shaft is mounted on the apparatus with the larger number of teeth (crown), therefore 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 gearbox for agricultural machinery distributor when there are at least two output shafts.
It really 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 amount of teeth. The gear shift of the primary couple of gears with the secondary types enables different speeds. The manual change of the secondary equipment set with gears with different quantity of teeth allows modifications to the result rotation speed.
