IH 2412B Loader Backhoe

[Rabbit Holler Flash]

Bought Scrivet a new project, IH 2412B loader backhoe "ran when parked" Have ordered all the manuals and Scrivet got it running but seems clutch is stuck or pilot shaft bearing is siezed. When it starts it GOES have tried bumping objects (stumps) kills it and locks you tight till cant pull out a gear. Anybody messed with this model of tractor and anybody got ideas short of breaking it into to replace clutch.
