I have a 2012 Snapper RZT26520 Zero turn. It has a B&S 26hp (44P777 5167 G5) engine on it. Engine works fine but the PTO seal on bottom of engine went bad and started leaking oil everywhere. I released the belts and removed the center bolt that holds the clutch on. Clutch would not move so i taped it with a hammer and nothing. I then tried a puller. no movement. Tried 2 more different types of pullers and even took yellow can of propane and heated it and actually tore the clutch up trying to get it off but base of clutch still stuck on engine shaft. Any body have experience with this kind of situation and is there a way to get it off? Thanks
