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 working torque can also be transmitted to the gearbox by hydraulic motors or belt pulleys, in addition 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 each other, the gearbox can be an ORTHOGONAL ANGLE gearbox or even more frequently gearbox for agricultural machinery called a right-angle gearbox.

rotary tiller gearbox is usually adopted middle gear transmission system, mounted with the tractor of 12-80HP. Tractor wheel tracks are completely protected after tillage as the operating width is a lot wider. The quality is reliable and the efficiency is well. So that it can be used on dried out and paddy field. It could reduce the time, 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 insight shaft, has the fewer number of teeth (pinion), hence the result 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), thus the output shaft rotates faster compared to the input shaft.
Right-angle gearboxes, distributors or rotational reverse gearboxes
When the gearboxes have gears with the same number of 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 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 may also have other gears with a different amount of teeth. The apparatus shift of the primary pair of gears with the secondary ones enables different speeds. The manual change of the secondary equipment set with gears with different number of teeth allows modifications to the result rotation speed.
