Agricultural Gearbox
The agricultural gearbox is the primary mechanical component of the kinematic chain of agricultural machines. It is normally powered 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, in addition to chain gears.
Agricultural gearboxes always have one input shaft and at least one output shaft. If these shafts sit at 90° to one another, the gearbox can be an ORTHOGONAL ANGLE gearbox or more commonly called a right-angle gearbox.
rotary tiller gearbox is definitely adopted middle gear transmission system, mounted with the tractor of 12-80HP. Tractor wheel tracks are totally covered after tillage as the functioning width is a lot wider. The product quality is reliable and the functionality is well. So it can be used on dry and paddy field. It can reduce the time, laboring, and price, etc. during operation
Increasers and Reducers
When the gearboxes have both gears with gearbox for agricultural machinery different numbers of teeth.
The gearbox is a reducer when the driving gear, i.e. the main one with the input shaft, has the fewer amount of teeth (pinion), thus the output shaft rotates slower than the input shaft.
It is called an increaser when the insight shaft is mounted on the apparatus with the larger quantity of teeth (crown), therefore the result 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 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 variations 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 number of teeth. The apparatus shift of the main couple of gears with the secondary types allows different speeds. The manual switch of the secondary equipment pair with gears with different number of teeth allows adjustments to the output rotation speed.
CMR GROUP will be able to design and manufacture also agricultural machinery applications.
