    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.

    IPC: E02F9/28

    Abstract: A tool bit is disclosed. The tool bit may comprise a threaded portion, a shank, a shoulder, an anti-rotation segment and a working portion. The threaded portion may be centered about and extend longitudinally along a first axis. The shank may be centered about the first axis and extend longitudinally along the first axis. The shank may be disposed between the threaded portion and the shoulder. The anti-rotation segment may be disposed between the shoulder and the working portion of the tool bit. The working portion may be oriented to extend lengthwise away from the first axis and to extend lengthwise along another axis that is transverse to the first axis. The working portion may include a planar cutting surface that includes a working edge. The planar cutting surface may be oriented transverse to the first axis.
