gearbox

Description

The gearbox receives drive from coupling (2) and transmits it, through hydraulically controlled gearbox (3), creeper (4), main

clutch (5) and 6-speed mechanical gearbox (7), to bevel pinion (8) and power take-off (9), which, in turn, transmits drive to the

front axle. The gearbox also has a double power take-off (6) to drive the hydraulic system pumps
