Agricultural Gearbox
The agricultural gearbox is 
the primary mechanical element 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 will have a single input shaft and at least one output shaft. If these shafts sit at 90° to one another, the gearbox can be an gearbox for agricultural machinery 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 covered after tillage as the operating width is much wider. The product quality is dependable and the efficiency is well. So it can be used on dried out and paddy field. It could decrease the time, laboring, and cost, etc. during operation
Increasers and Reducers
When the gearboxes have both gears with different numbers of teeth.
The gearbox is a reducer when the driving gear, i.electronic. the one with the insight shaft, gets 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 number 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 the teeth.
The gearbox is known as 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 really is called a rotational reverse gearbox and parallel offset in the variations with parallel shafts with two gearboxes.
Speed change
in addition to the main pair of gears and relevant shafts, the gearboxes could also have other gears with a different amount of teeth. The apparatus shift of the main pair of gears with the secondary types allows different speeds. The manual change of the secondary gear set with gears with different amount of teeth allows modifications to the result rotation speed.
