Depending on the desired functionality of the vehicle's body, several variants of clutch-dependent power take-off systems are available. This means, the input power is taken from the countershaft of the manual gearbox. The pneumatically activated PTO is only possible with the vehicle in parked position. These power take-off systems allow the operation of hydraulic pumps which supply the hydraulic pressure necessary for tilting the loading area, removing lifting platforms, or compressors.
