A trencher that is convertible between first and second trenching configurations so that when the trencher is in the first trenching configuration, a trencher boom includes a first trenching portion at the distal end of the boom and a second trenching portion that extends along a longitudinal axis from the first trenching portion toward the proximal end. The first trenching portion defines a first trench width, and the second trenching portion defines a second trench width. The first trench width is larger than the second trench width. The second trenching portion has a greater length measured along the longitudinal axis as compared to the first trenching portion.

Aspects of the present disclosure relate to an apparatus including a drum rotatable about an axis of rotation and a support mount secured to the drum. The apparatus includes a support mount defining first and second fastener openings and first and second anchor openings. A replaceable holding block mounts to the support mount and the replaceable holding block has a front face and a rear face. The replaceable holding block defines a first fastener opening, a second fastener opening, and a tooth opening that extend through the replaceable holding block from the front face to the rear face. The first and second fastener openings of the replaceable holding block align with the first and second fastener openings of the support mount when the replaceable housing block is mounted to the block mounting surface. A tooth is secured to the replaceable holding block at the tooth opening.

Replaceable mounting apparatus for reducing elements

A cutting element including an arcuate base having a first side, a second side, an outer radial surface, and an inner radial surface, the inner radial surface being configured to be mounted to a cutting drum. The cutting element also includes a plurality of tooth holders being mounted to the outer radial surface of the arcuate base, the tooth holders being configured to receive cutting teeth. Additionally, the cutting element includes a cutting tooth mounted in each tooth holder, wherein there is at least one leading tooth, and at least one trailing tooth, each of the cutting teeth being configured to cut through a dissimilar cutting plane, wherein each dissimilar cutting plane is parallel to one another.

The present disclosure relates to an air cleaning system for an off-road excavation apparatus. The off-road excavation apparatus includes an excavating component and a shroud assembly that at least partially covers the excavating component. The shroud assembly includes a first shroud component and a second shroud component. The first shroud component is moveable relative to the second shroud component to allow access to the excavating component. The air cleaning system draws air from inside the shroud assembly and includes an air cleaner, an air conduit and an air moving device that are all carried by the first shroud component as the first shroud component is moved relative to the second shroud component.

A low height pivot arrangement allows an excavation tool of a surface excavation machine to be pivoted between an upper transport position and a lower excavating position. The low height pivot arrangement assists in reducing a moment arm of the excavation tool when the excavation tool is raised during non-excavating operations.
