Abstract

A cutter head includes first and second mounts that are configured to allow coupling with various motive equipment, such as a tractor or an excavator. The first mount may be mounted on the rear of the cutter head chassis for coupling with the tractor, while the second mount may be mounted on the top of the cutter head chassis for coupling with the excavator. A pressure gauge includes an adjustment arrangement such that the position of the display of the pressure gauge can be adjusted for viewing of the operator of the tractor or excavator. The cutter head may include a cooler assembly that works off or in conjunction with a primary cooler assembly of the tractor or excavator. The cutter head may include an excavator linkage equipped with a bushing assembly.
