Agricultural Gearbox
The agricultural gearbox is the primary mechanical element 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 operating torque can also be transmitted to the gearbox by hydraulic motors or belt pulleys, in addition to chain gears.
Agricultural gearboxes will have a single input shaft and at least a single output shaft. If these shafts are positioned at 90° to each other, the gearbox is an ORTHOGONAL ANGLE gearbox or more typically called a right-angle gearbox.

rotary tiller gearbox can be adopted middle equipment transmission system, mounted with the tractor of 12-80HP. Tractor wheel tracks are completely protected after tillage as the working width is much wider. The product quality is reliable and the functionality is well. So 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.electronic. the main one with the input shaft, has the fewer quantity of teeth (pinion), hence the output shaft rotates slower than the input shaft.
It is called an increaser when the input shaft is mounted on the apparatus with the larger amount 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 known as 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 gearbox for agricultural machinery reverse gearbox and parallel offset in the variations with parallel shafts with two gearboxes.

Speed change
in addition to the primary pair of gears and relevant shafts, the gearboxes may also have various other gears with a different quantity of teeth. The apparatus shift of the primary couple of gears with the secondary ones enables different speeds. The manual change of the secondary equipment pair with gears with different number of teeth allows modifications to the result rotation speed.
CMR GROUP will be able to design and manufacture also agricultural machinery applications.
