Hydraulic pressure build up. Loader valve was getting too hot to touch, so we replaced w new one w float set at 2250 psi. Hydraulics worked ok, then new loader valve started getting hot. Then one of the lift cylinder seals blew. We had that fixed and reinstalled, then new hydraulic pump seals blew out. Waiting on pressure gauge to check hydraulic pressure. Cleaned out breather dipstick in reservoir. Don't know what else to check. Never had a tractor do this. Everything else on tractor works.
