A soil processing machine, in particular a soil compactor, comprises a machine frame and a casing () carried on the machine frame and/or at least partially providing it and bounding a unit receptacle space (), wherein the casing () has a cooling air inlet area () and a cooling air outlet area () for cooling air flowing through the unit receptacle space (), wherein a plurality of units around which cooling air can flow through the unit receptacle space () from the cooling air inlet area () to the cooling air outlet area () are arranged in the unit receptacle space (), wherein at least two of the units arranged in the unit receptacle space () have maximum permissible operating temperatures different from one another and at least one unit having higher maximum permissible operating temperature is arranged upstream in a cooling air flow direction from the cooling air inlet area () to the cooling air outlet area () with respect to at least one unit having lower maximum permissible operating temperature.

Soil processing machine

A soil processing machine, in particular a soil compactor, includes at least one drive roller and an electrohydraulic drive system for driving at least one drive roller. The drive system has a traction hydraulic circuit having at least one hydraulic motor and at least one hydraulic pump. The circuit includes a first line region between a first connection fitting of the at least one hydraulic pump and a first connection fitting of each hydraulic motor to drive the at least one drive roller in a first rotatable direction and a second line region between a second connection fitting of the at least one hydraulic pump and a second connection fitting of each hydraulic motor to drive the at least one drive roller in a second, opposite rotatable direction. A valve assembly is provided with each line region for selectively interrupting and releasing a fluid flow connection between the at least one hydraulic pump and at least one hydraulic motor.

Soil processing machine and method for operating a soil processing machine

A compactor roller for a soil compactor comprises an oscillation mass assembly () including at least one oscillation shaft () rotatable about an oscillation-shaft axis of rotation eccentric to a compactor-roller axis of rotation, which oscillation mass assembly () includes at least one oscillation unbalance mass (), and a vibration mass assembly () including a vibration shaft () rotatable about a vibration shaft axis of rotation (D), which vibration mass assembly () includes at least one vibration unbalance mass (), wherein at least one oscillation shaft () and the vibration shaft () are carried in the compactor roller () such that they can be driven to rotate.
