Need Help. L3560HSTC and the PTO will not engage. Knob turns and locks down, PTO symbol lights up on the electronic dash. Stand up from seat and the tractor shuts off like it should, but the PTO is not turning. Any body know if we have a fuse for the PTO. Anybody know where the PTO clutch is located. maybe I've knocked a wire off. Worked fine on Saturday. Any help would be appreciated.
