i bought 4 woodland pro chains (2) 68DL and (2) 72DL chain loops in chisel. the 68s were put on a husky 55 and the 72s were installed on a Husky 455. after about 5 min of great cutting both chains went dull like they were running backwards. we were cutting about a 16" hickory tree. do anyone have any idea on what would cause this?
