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 operating 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 1 output shaft. If these shafts sit at 90° to each other, the gearbox is an ORTHOGONAL ANGLE gearbox or more commonly called a right-angle gearbox.
rotary tiller gearbox is usually adopted middle gear transmission program, mounted with the tractor of 12-80HP. Tractor wheel tracks are completely protected after tillage as the working width is much wider. The quality is reliable and the efficiency is well. So it can be used on dried out and paddy field. It could 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.e. the one with the insight shaft, has the fewer quantity of teeth (pinion), thus the result shaft rotates slower compared to the input shaft.
It is called an increaser when the insight shaft is mounted on the gear with the larger number of teeth (crown), therefore 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 tooth.
The gearbox is called 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 reverse gearbox and parallel offset in the versions with parallel shafts with two gearboxes.
in addition to the main pair of gears and relevant shafts, the gearboxes may also have other gears with a different quantity of teeth. The gear shift of the primary pair of gears with the secondary types enables different speeds. The manual switch of the secondary gear set with gears with different number of teeth allows adjustments to the output rotation speed.
