Abstract: A filler adaptor assembly includes a base, an outer ring, and iris members. The base has a central opening. The outer ring is disposed circumferentially about the base and is rotatable relative to the base. The iris members are pivotably coupled to the base. The iris members cooperate to define an iris opening and are movable to vary the iris opening. The iris members are coupled to the outer ring, and move between an open position and a closed position when the outer ring is rotated relative to the base.

Abstract: Cleaner teeth or bars are used in many applications to remove debris from a compacting wheel that is wedged between respective rows of compacting tips. It is advantageous to have a cleaner tooth that is simple in construction and effective to remove the debris with the least amount of effort. In the subject arrangement, a cleaner tooth is provided having an arcuate upper surface that, in use, is located immediately adjacent an outer peripheral surface of a compacting wheel and has a trailing lower surface that intersects the arcuate outer surface at a forward end portion thereof. The forward end portion is effective to remove the debris with minimal effort. A fastening portion provides a structure which allows ease of assembly and disassembly of the cleaner tooth to a compacting machine.
