<p>A segmented blade (600,800) comprised of overlapping blade segments (100,300,500) is disclosed herein. Each blade segment (100) overlaps with adjacent segments (400,300,500) 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 (160,165) through which a bolt (805) detachably connects the overlapped sections of adjacent blade segments with the moldboard (200). Such a connection increases the strength of the connection as well as the strength of the moldboard (200) in the region of the connection. This allows for smaller blade segments (100,300,500) 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 (200) and/or the longevity of the moldboard (200).</p> |
