Abstract: A soil processing roller includes an elongated roller shell that rotates about a roller axis of rotation and a first fluid chamber in a roller interior space delimited by the roller shell. In association with the first fluid chamber a first opening group is provided which includes a first filling opening, a first discharge opening and a first fill level control opening. A shielding element is arranged in an axial end region of the roller interior space which does not rotate about the roller axis of rotation during a soil processing operation. A first release recess is provided in the shielding element, and a second fluid chamber substantially separated from the first fluid chamber against fluid exchange is delimited by the roller shell. In association with the second fluid chamber a second opening group is provided which includes a second filling opening, a second discharge opening and a second fill level control opening.

Abstract: A work machine includes a frame, a sensor assembly, and an ultrasonic sensor. The frame includes a first portion and a second portion that includes a front bumper and is configured to pivot with respect to the first portion for steering the work machine. The sensor assembly is positioned on the first portion or the second portion of the frame and is configured to sense data for detection of obstacles within a first area around the work machine. The ultrasonic sensor is positioned on the front bumper of the second portion and is configured to sense data for detection of obstacles within a second area around the work machine, the second area outside the first area when the second portion is in an articulated position with respect to the first portion.

Abstract: A wheel guard includes a guard member disposed on a compactor wheel. The guard member has a first side having a first portion and a second portion. The second portion is offset from the first portion such that to define a first stepped recess therein. The guard member has a second side disposed opposite to the first side. The first portion has a first cross-sectional thickness and the second portion has a second cross-sectional thickness such that the second cross-sectional thickness is lesser than the first cross-sectional thickness. The guard member has a first top surface defined by the first portion, and a second top surface defined by the second portion and partially by the first portion. The second top surface is offset from the first top surface such that to define a second stepped recess therein. The wheel guard includes a base plate and a wear pad coupled thereto.

Abstract: A guard for protecting a drain plug and a ground-facing surface of an axle housing on a machine including a first portion and a second portion. The first portion has a body configured to be mounted to the axle housing to protect at least portion of the ground-facing surface of the axle housing. The body includes an opening configured to allow access to and removal of the drain plug through the opening. The second portion is removably couplable to the first portion. When the second portion is attached to the first portion, the second portion covers the opening to protect the drain plug. When the second portion is removed, the drain plug is accessible and removable to service oil in the axle housing.
