Abstract
The invention relates to a mobile machine having a traction drive and working hydraulics. The drive unit has a radial piston pump which is driven by a drive set and supplies working hydraulics. The radial piston pump is arranged on the axis of the output drive shaft of the drive set, between the drive set and a gearbox which is connected thereto via the output drive shaft. The drive set, the radial piston pump and the gearbox in this case form a compact drive unit.
