Abstract

A soil processing machine, in particular a soil compactor, comprises a machine frame and a casing (26, 28) carried on the machine frame and/or at least partially providing it and bounding a unit receptacle space (24), wherein the casing (26, 28) has a cooling air inlet area (30) and a cooling air outlet area (32) for cooling air flowing through the unit receptacle space (24), wherein a plurality of units around which cooling air can flow through the unit receptacle space (24) from the cooling air inlet area (30) to the cooling air outlet area (32) are arranged in the unit receptacle space (24), wherein at least two of the units arranged in the unit receptacle space (24) 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 (30) to the cooling air outlet area (32) with respect to at least one unit having lower maximum permissible operating temperature.
