Agricultural Gearbox
The agricultural gearbox is the primary mechanical component of the kinematic chain of agricultural machines. It really 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 a single input shaft and at least a single 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-angle gearbox.
rotary tiller gearbox can be adopted middle equipment transmission program, mounted with the 
tractor of 12-80HP. Tractor wheel tracks are completely covered after tillage as the working width is much wider. The quality is dependable and the functionality is well. So that it can be utilized on dry and paddy field. It could 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 amount of teeth (pinion), hence the output shaft rotates gearbox for agricultural machinery 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), therefore the output shaft rotates faster than the input shaft.
Right-angle gearboxes, distributors or rotational invert gearboxes
When the gearboxes have gears with the same number of the 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 reverse 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 various other gears with a different amount of teeth. The apparatus shift of the main pair of gears with the secondary ones allows different speeds. The manual switch of the secondary gear pair with gears with different quantity of teeth allows adjustments to the result rotation speed.
CMR GROUP will be able to design and manufacture also agricultural machinery applications.
