Doug - Sounds like the hydraulic control valve has stuck in either the lift or drop position. This loads (dead heads) the pump so flow is bypassed continuously thru the relief valve. It will heat up the entire hydraulic system VERY quickly.

Check to see if the remote valve is stuck – it should center by spring action from both extremes of travel.

If the tractor has a remote 4 way (“Christmas tree”) valve with hoses running to a coupler at the rear of the tractor, it is indeed stuck and you don’t need hydraulics, you can connect the two hoses together to take the load off the pump. Or if it has a belly pump you can simply remove the pump drive shaft (a 5 minute job) to disable the pump.
