A central pressure limiting valve communicates a hydraulic pressure source with a hydraulic supply line. The hydraulic supply line communicates the central pressure limiting valve with the piston-cylinder units of all four crawler tracks. A common pressure accumulator is communicated with all four of the piston-cylinder units.
