I've been having problems with the 54" snow blower PTO shaft "quick" connects. In several cases, they've been nearly impossible to remove (I spent an hour yesterday trying to remove the mid-PTO connection). The connector is less substantial than the one that came with my 62D mower deck (it's made with light weight steel and only has two ball bearings). The connector for the mower deck is made from a heavier casting and has four guide bearings in addition to the two that lock onto the PTO. I've never had a problem with the 5-year old mower deck quick connect.
Has anyone experienced the same problems? I've disassembled the quick connects to clean / grease them, but it doesn't fix the problem. I use a light weight water-proof grease in the fittings and, with temperatures in the 20s-30s F, still have trouble installing / removing the quick connects.
Have you replaced the light weight quick connect on the snow blower shaft that attaches to the mid PTO? What part(s) did you use? How hard was it to disassemble the U-joint? There's no locking ring to remove so imagine the pins are a press fit.
