This Hardened Spring Steel clip bends over the gauge wheel arm where it pivots on the arm stop.  Over time, large divots wear into the gauge wheel arm in these locations, changing planting depth.  Fill in any wear with weld or other product, grind it smooth and place a wear clip over the top, to give yourself a better than new surface for your gauge wheel arms to ride on!  Fits all Deere 1700 planters.
