Hydrostatic transmission

The compact hydrostatic pump-engine unit is made of light alloy so that the machine can be easily manoeuvred and positioned on the gearbox.

Characterised by a high pressure circuit which is separate from the one of the PowerSafe® clutch, the machine is fitted with an axial-centrifugal fan to cool the hydrostatic unit.
