This component is the replaceable wear element for the straw-walker assembly in a grain harvester. It sits on the walker bed and is struck repeatedly by the threshing drum discharge, helping to convey and separate the remaining grain from the straw mat. Over time, the contact surface erodes from the abrasive action of crop material and the impact of the drum. A worn element reduces conveying efficiency and can allow straw to bunch, leading to increased grain loss out the rear of the machine. The manufacturer machines this element to the same profile and hardness as the original, so it seats correctly in the walker frame without requiring shimming or modification.
