It's been a long time since I put my snow blower on my 737. In attempting to swing from a back implement to a front implement one of my control rods won't pivot around. It's the rod that controls engaging/disengaging the PTO. I can't tell if if it is supposed to twist around at the bottom of the rod or in the flex joint above the rubber half-donut thing. I don't want to force it just in case one of you can tell me which part I should focus on. WD 40 hasn't had any effect. Or does anyone know a BCS mechanic I could call? I'm up in Alaska and I can't find anyone who knows the machine.
