Abstract: Disclosed is a drive tumbler or sprocket for driving a continuous track comprising replaceable drive lugs. The drive tumbler comprises a tumbler tire radially extending from the hub cylinder comprising radially extending slots spaced around the tumbler tire. The replaceable lugs are adapted to frictionally engage the sides of the slots and are removably attached in the slots. The lug comprises one or more nubs protruding from the top lug face for engagement with a continuous track and for transferring torque from the drive shaft to the continuous track.

Abstract: A tool insert is provided for increasing the operating life of a tool bit made of both the tool insert and an associated tool body. The tool insert provides at least partial protection from wear during use of the tool bit and includes a tip free of hard edges or creases that increases the operating life of the tip. The tip may include a portion that has a diameter at least equal to or larger than the diameter of the connection end of the tool body. This increases the shielding ability of the tool insert during use and extends the operating life of the tool bit. The tool insert may comprising a cylindrical stem for engagement with the tool body, the cylindrical stem having a free base end opposite a body end; and a tip connected for engaging a worked surface, the tip comprising an outer surface without hard edges.

Abstract: A tool shield retainer clip for securing a removable tool to a tool carrier blade, and shielding the tool carrier blade is disclosed herein. The tool shield retainer clip includes a front section including an aperture for receiving a tool, a back section adjacent the front section, a tail flange connected to the back section opposite the front section, and a top section adjacent the front section and opposite the back section.

Abstract: A segmented blade comprised of overlapping blade segments is disclosed herein. Each blade segment overlaps with adjacent segments thereby providing for an overlapping joint between segments. The overlapping joint reduces erosion and/or washout of the underlying moldboard. Further, in one embodiment, the overlapping joint may include a connector hole such as a bolt hole through which a bolt detachably connects the overlapped sections of adjacent blade segments with the moldboard. Such a connection increases the strength of the connection as well as the strength of the moldboard in the region of the connection. This allows for smaller blade segments to be used and allows for segments which are of a suitable size to be manhandled by a single operator without jeopardizing the strength of the moldboard and/or the longevity of the moldboard.

Abstract: A blade assembly for use on a surface working machine includes a moldboard. The moldboard includes a lower mounting section including a mounting edge for mounting a plurality of blade sections thereto. The blade assembly further includes a plurality of blade segments for detachable connection to the lower mounting section of the moldboard and adapted to overlap with any adjacent blade segment when mounted to the moldboard. Each blade segment includes a front face for forward machine orientation, a back face opposite the front face, a right edge including a first overlap section, and a left edge including a second overlap section. The first overlap section shaped for overlap with the second overlap section of an adjacent blade segment so that when mounted to the moldboard adjacent blade segments substantially abut each other.
