I'm looking for a rear wheel for my 165 hydro. The left wheel is frozen in place. I think the key might be distorted. I've tried everything, wheel pullers, a rigged up puller using a chain and a bottle jack, heating it red hot with a torch, and this wheel is there to stay. If I can find a replacement, I'll cut it off. Until then, I put a tube in the tire, while still attached to the tractor. What a HUGE PITA !
