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 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 can be an ORTHOGONAL ANGLE gearbox or even more generally called a right-angle gearbox.
rotary tiller gearbox is adopted middle gear transmission system, mounted with the tractor of 12-80HP. Tractor wheel tracks are totally protected after tillage as the functioning width is a lot wider. The product quality is reliable and the overall performance is well. So that it can be used on dry and paddy field. It can decrease 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.e. the main one with the insight shaft, has the fewer number of teeth (pinion), therefore the output 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 amount of teeth (crown), hence the result 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 really is called a distributor whenever 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 gearbox for agricultural machinery addition to the main couple of gears and relevant shafts, the gearboxes may also have additional gears with a different amount of teeth. The apparatus shift of the primary 
couple of gears with the secondary ones enables different speeds. The manual switch of the secondary gear pair with gears with different number of teeth allows adjustments to the result rotation speed.
CMR GROUP will be able to design and manufacture also agricultural machinery applications.
