Scooting along with the trusty 8-ft 3-pt Kodiak and all of a sudden it just seemed to lock up. Happened so fast i didn't get the PTO lever off til it killed the tractor (which means the slip clutch ain't slipping) None of the gearboxes were hot. Pulled out of the grass, looked it over and under it, turned it over by hand saw nothing strange. Engaged PTO at near idle and it was about to tighten up so headed for the shed. About to get some wrenches and another rain storm. I'm going to hook it to another tractor as I write this it crossed my mind that maybe something in the tractor's PTO failed!
