A base block for a cutting drum is disclosed. The base block may have a first end. The first end may have an opening configured to receive a tool. The first end may also have a flat surface surrounding the opening. The base block may have a second end configured to abut the cutting drum. The base block may further have an internal passageway commencing at the opening configured to receive the tool. The passageway may define a longitudinal axis that is offset by an acute angle from being perpendicular to the flat surface.

Cutter assembly configured to allow tool rotation

Work machines such as road mills having a frame supported by tracked or wheeled ground engaging support units may require the ability to move one or more of the ground engaging units between projecting and retracted positions relative to the frame without reversing the running direction of the repositioned unit. A disclosed work machine has a machine frame supportable by a plurality of ground engaging units. A support device connected between the machine frame and at least one of the ground engaging units has a lifting column adapted to controllably raise and lower the ground engaging unit relative to the frame. A first actuator is connected to the support device to move the one ground engaging unit between the projecting and retracted positions, and a second actuator is connected to the lifting column to maintain the running direction of the associated ground engaging unit in each of the projecting and retracted positions.

Milling machine

A work machine includes a frame () supported by a plurality of wheels or tracks (), at least some of which are associated with respective lifting columns () adapted to raise and lower the frame () relative to the respective wheels or track (). A work tool is supported by the frame (), and a drive mechanism is adapted to rotate the work tool and at least one of or tracks (). An articulation apparatus () uses a first actuator () and a pivoting support arm () to move one of the wheels or tracks () between a projecting position and a retracted position relative to the frame (). The articulation apparatus () includes a second actuator () adaped to rotate the wheel or track () about a vertical axis (Z).

Milling machine with re-entering back wheels

A work machine having a frame, a work tool and an articulation apparatus so as to pivot at least one support wheel mounted at the frame from a projecting position to a retracted position and vice versa.

Cold planer

A vibratory mechanism is provided for a compacting work machine . The vibratory mechanism includes a first/outer eccentric weight and a second/inner eccentric weight . The second weight has a cavity with a movable mass that when rotated in a first direction opposes the first eccentric weight and when rotated in a second direction the movable mass combines with the first eccentric . The second eccentric weight is also manually indexable relative to the first eccentric to a plurality of distinct positions giving a plurality of different amplitude vibratory impact forces when rotated in either of the first and second directions
