Ground processing machine

A ground processing machine having two drive rollers arranged one after the other in a machine longitudinal direction and rotatable about a respective axis of rotation, wherein each drive roller comprises two drive roller segments arranged one after the other in the direction of the associated axis of rotation, and having a hydraulic drive system for the drive rollers, wherein the hydraulic drive system comprises:

• in association with a first drive roller segment of the two drive rollers, a first traction drive hydraulic motor,
• in association with a second drive roller segment of the two drive rollers, a second traction drive hydraulic motor,
• in association with a third drive roller segment of the two drive rollers, a third traction drive hydraulic motor,
• in association with a fourth drive roller segment of the two drive rollers, a fourth traction drive hydraulic motor,
• a first traction drive hydraulic pump,
• a second traction drive hydraulic pump,
• at least one drive motor for driving the first traction drive hydraulic pump and the second traction drive hydraulic pump for supplying hydraulic fluid to the traction drive hydraulic motors,
• wherein:
• a first fluid connection of the first traction drive hydraulic pump is connected or connectable by means of a first hydraulic line to a first fluid connection of the first traction drive hydraulic motor and a first fluid connection of the second traction drive hydraulic motor,
• a first fluid connection of the second traction drive hydraulic pump is connected or connectable by means of a second hydraulic line to a first fluid connection of the third traction drive hydraulic motor and a first fluid connection of the fourth traction drive hydraulic motor,
• a second fluid connection of the first traction drive hydraulic pump is connected or connectable by means of a third hydraulic line to a second fluid connection of the second traction drive hydraulic motor and a second fluid connection of the third traction drive hydraulic motor,
• a second fluid connection of the second traction drive hydraulic pump is connected or connectable by means of a fourth hydraulic line to a second fluid connection of the first traction drive hydraulic motor and a second fluid connection of the fourth traction drive hydraulic motor.
