A soil processing machine, in particular a soil compactor, comprising at least one battery () supported on a machine frame () and at least one consumer of electrical energy () fed from the at least one battery (), further comprising at least one interchangeable charging module () which is detachably supported on the machine frame (), has a battery connection region () for connecting the at least one interchangeable charging module () to a battery management system (), and has a voltage supply connection region () for connecting the at least one interchangeable charging module () to an external voltage source.

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.
