Need a bit of help. I need to pul the PTO off of my dad's '98 Snapper LT160H42DBV riding mower. I got up under there with a socket and started turning the bolt. It turns the engine. I assume I need to lock up the flywheel somehow? I don't want to break anything further. Also, anyone have a line of a good parts source with real people to help. I need the plug for the PTO, it shorted and burned up. I can find a PTO, but the plug is a bear. Thanks!
