Agricultural Gearbox
The agricultural gearbox is the primary 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 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 one output shaft. If these shafts sit at 90° to each other, the gearbox can be an ORTHOGONAL ANGLE gearbox or even more frequently called a right-position gearbox.
rotary tiller gearbox is adopted middle gear transmission program, mounted with the tractor of 12-80HP. Tractor wheel tracks are completely covered after tillage as the working width is a lot wider. The product quality is dependable and the overall performance is well. So that it can be utilized on dried out 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.electronic. the one with the input shaft, gets the fewer amount 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), thus 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 teeth.
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 is called a rotational invert gearbox and parallel offset in the variations with parallel shafts with two gearboxes.
Speed change
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 couple of gears with the secondary ones allows different speeds. The manual change of the secondary gear pair with gears with different quantity of teeth allows adjustments to the output rotation speed.
CMR GROUP will be able to design and manufacture also agricultural machinery gearbox for agricultural machinery applications.
