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.

A control system for a compactor is disclosed. The control system can include any one or combination of one or more position sensors, a steering system, a control interface and a controller. The controller can be in communication with at least the control interface and the one or more position sensors. The controller can be configured to receive data recording a position of the compactor when physically operating the compactor along at least a portion of the desired boundary of a compaction area, determine from the data a virtual boundary of the compaction area corresponding to the position of the compactor when physically operating the compactor along the desired boundary of the compaction area, and generate at least a first work plan for operating the compactor to compact in the compaction area up to the virtual boundary.

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.

The present invention relates to a ground compaction machine for compacting a ground, in particular a tandem roller, a single-drum roller, a rubber-wheeled roller or a trench roller, comprising a machine frame, at least one travel unit with a wheel or a roller drum, a travel drive for driving the travel unit, and a steering drive for adjusting the traveling direction of the ground compaction machine, the ground compaction machine comprising at least one electric motor. The present invention also relates to a method for operating a ground compaction machine.

A guard for a compactor vehicle that includes a base and a cap. The base comprises a body and a retention feature. The body defines an underside, configured to engage a wheel of the compactor vehicle, and an opposing cap-facing side. The cap comprises an outer surface and a retention feature. The outer surface defines a compaction surface. The retention features of the base and cap interlock with one another to secure the cap to the base. A cavity is defined in the underside of the base.

In a self-propelling road construction machine, particularly a road roller (1), comprising a travel drive, a steering device, a control device (30) for the travel drive and the steering device, and a driver's seat (5) rotatable by at least 180° and including an integrated operating element (8) for the vehicle speed, with the operating element (8) generating the control signals for the travel drive in dependence on the direction of the control movement of the operating element (8) or the direction of force application on the operating element (8), it is provided that, in response to a first switching command, the control device (30) will automatically perform a reversing process comprising deceleration, seat rotation, change of direction of travel, and acceleration to the set vehicle speed in opposite direction to the original direction of travel.
