Pete, I am betting you have a three position HHC and a 300 head. I would be sure that cutter bar is able to go to the bottom of its stroke when head is raised. Be sure that all the pivoting linkage is allowing free floating without binding. Be sure that ground presure springs or wobble box counterbalance spring isn't holding bar from floating fully. If all that is OK you may need to adjust the turnbuckle from the feeler shaft lever to switch assembly a little one way or the other to get it in a more active zone. Good luck. Dan
