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 operating torque can 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 1 output shaft. If these shafts sit at 90° to one another, the gearbox can be an ORTHOGONAL ANGLE gearbox or more typically called a right-position gearbox.
rotary tiller gearbox can be adopted middle gear transmission program, mounted with the tractor of 12-80HP. Tractor wheel tracks are totally covered after tillage as the working width is a lot wider. The quality is reliable and the efficiency is well. So that it can 
be used on dry and paddy field. It can decrease the time, laboring, and cost, etc. during operation
gearbox for agricultural machinery Increasers and Reducers
When the gearboxes have both gears with different amounts of teeth.
The gearbox is a reducer when the driving gear, i.e. the one with the input shaft, has the fewer quantity of teeth (pinion), thus the result shaft rotates slower than the input shaft.
It is named an increaser when the insight 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 teeth.
The gearbox is called right-angle when it only has two shafts (input and output),
whereas it really is called a distributor when there are at least two output shafts.
It is called a rotational invert 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 could also have additional gears with a different amount of teeth. The gear shift of the primary couple of gears with the secondary types enables different speeds. The manual switch of the secondary gear pair with gears with different number of teeth allows modifications to the output rotation speed.
