摘要： The assembly comprises a rotatable body for supporting rollertype earth cutters, and means for mounting the earth cutters to the body, in which the cutters are so configured and mounted as to cooperate, upon rotation of the body, to define at least one, overall circular and convex cutting surface of the assembly.

摘要： The means comprises a flat plate having a mounting limb carried at substantially a right angle, for mounting thereof to a shaft support so that the plate will close upon an axial end of an earth cutter rotatably carried on the shaft. Thus, a clearance space defined between the earth cutter and the shaft is shielded against the entry of dust, rock chips, mud, water and such detritus. The shielding means is designed to prolong the life of bearing seals, and bearings as well, especially where such are in earth cutter use.

摘要： The means comprises a pair of spaced-apart walls which have arcuate recesses therein for receiving the flatted ends of an earth cutter shaft. Retainers fit across the flats formed in the ends of the shaft and are secured within the recesses and against camming surfaces of the walls. In response to any unwanted undesirable rotation of the shaft, the retainers rotate relative to an axial center of the shaft to force ends thereof, which abut the camming surfaces more securely into the recesses so that the retainer is jammed or wedged in place. This results in positively inhibiting further rotation of the shaft.
