A leg tube assembly for a work machine includes a first tube coupled with a frame of the work machine and a second tube coupled to the first tube and slidable relative to the first tube between an extended position and a retracted position. The first tube defines a first inner surface. The second tube includes a tube body defining a second inner surface, a second outer surface, a first end, and a second end. The tube body defines at least one recess on the second outer surface. The second tube includes at least one support member disposed within the at least one recess of the tube body between the first tube and the tube body of the second tube. The at least one support member is adapted to engage with the first inner surface of the first tube and includes any one of a bearing and a wear pad.

A tooling for removing a bit holder from a base block of a milling drum. The tooling includes a bracket, a pry tool, and an actuation member. The bracket is configured to be engaged with the bit holder and defines an impact surface to receive one or more impacts. The pry tool has a portion configured to be positioned between the bit holder and the base block. The actuation member is movably engaged with the bracket and is actuatable to contact and exert a pushing action on the pry tool to move and advance the portion of the pry tool into an interface defined between the bit holder and the base block. When the impact surface receives the impacts, impact components are correspondingly transferred to the pry tool to supplement the pushing action for a removal of the bit holder from the base block.

In a rotary mixer having a floating ground guard mounted for vertical movement relative to the frame and relative to the rotor, an actuator configured to provide movement in at least a vertical plane relative to the frame, and a ground guard dislodging tool coupled to the floating ground guard. The ground guard dislodging tool and the actuator are disposed such that the actuator engages and exerts a force on the ground guard dislodging tool to move the floating ground guard in a downward direction relative to the frame.

Some examples described herein include a flexible hopper for a conveyor system. The flexible hopper may include a hopper weldment attached to a frame of the conveyor, wherein the hopper weldment surrounds a charge end of the conveyor, a flexible connector that is attached to the hopper weldment and configured to enable an opening of the flexible hopper to expand or contract, and a flexible skirt that is folded over the flexible connector. The flexible skirt may include a plurality of flexible strips configured to form an enclosure between the flexible connector and the hopper weldment.
