Agricultural Gearbox
The agricultural gearbox is the main mechanical component 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 always have a single input shaft and at least a single output shaft. If these shafts are positioned at 90° to each other, the gearbox can be an ORTHOGONAL ANGLE gearbox or more commonly called a right-angle gearbox.

rotary tiller gearbox is adopted middle equipment transmission program, mounted with the tractor of 12-80HP. Tractor wheel tracks are completely covered after tillage as the functioning width is a lot wider. The product quality is reliable and the overall performance is well. So 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 the two gears with different numbers of teeth.
The gearbox is a reducer when the driving gear, i.e. the one with the input shaft, gets the fewer number of teeth (pinion), therefore the result 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 result 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 tooth.
The gearbox is called right-angle when it only has two shafts (input and output),
whereas it 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 variations 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 quantity of teeth. The apparatus shift of the main couple of gears with the secondary ones allows different speeds. The manual switch of the secondary equipment pair with gears with different amount of teeth allows adjustments to the result rotation speed.
