I have an old Super Z and I’m trying to pull the deck to do some welding on it. The deck pusher bars should just unbolt from the frame bracket. No dice. The nut came off no problem but the bolt is stuck. I tried the impact wrench but the bolt goes through an internal bearing at the end of the support arm and just spins. I tried hammering it out, again it won’t budge. It’s like the bolt threads have worn a groove or something in the bearing hole and it’s locked in there. Has anyone had to mess with this before? I can’t even cut the bolt without spreading the frame bracket because there’s no clearance. I guess I could unbolt the pusher assembly from the rear of the deck but I really want that bolt out now. Anyone else ever deal with this?
