Recenty had to replace weak hyd pump. I think I want to flush hyd-trans and fel. Considering mixing 50-50 diesel-utf, running ubtil warm (working fel and 3ph and driving in each gear) draing overnight and refilling with utf. Somewhat concerned about getting all of mix out but system hold 5 gal plus fel probably 1/2- 1 gal. Anyone tried this? Advice please. Thanks. Dan

That's a good thing to do. Just before you sell the tractor to someone you don't like. ....

Auerbach is right, that was OK in old Farmall "H"'s etc. where 99% ran out with the first drain and there were no wet clutches, or super close tolerances to be concerned with. Expensive as the correct fluid may be it will be cheap in the long run to use it as a flush. Most modern tractors have enough clutch pack systems, internal wet brake systems, internal and external lines, three point rams, etc, etc, that all contain fluid that never drains even with every drain plug remeoved. Be sure to clean the suction screens and change any filters too. Frank. ....

After speaking to a tractor dealership mechanic I've decided you guys are right ,will flush again in about 10 hrs check for debris. Thanks for the replys. Dan ....

And what to do with the used hyd fluid? Works fine as a rust deterrant when sprayed on the underside of vehicles. ....
