While mowing yesterday the yoke with the sleeve that connects to the front mount mower broke. What was left was the square shaft that fits inside the sleeve and connects to the mower deck. That part looks fine. I decided to order the yoke and sleeve assembly as all that was left was the splined yoke and it needed bearings. I went to unhook the splined yoke at the PTO shaft and it would not budge. I used about a can of PB Blaster. lol Since I am going to replace the splined yoke I didn't care if I damaged it further trying to get the damn thing unhooked as long as I didn't damage the PTO shaft itself. I removed the spring and I didn't see any steel balls. The thing still won't budge. Any ideas or tips would be greatly appreciated. I'm thinking about a propane torch to heat it. Good or bad idea?
