I bought a 430 over the phone. When I saw it was the dirtiest tractor I'd seen. But it was a CASE. It was different than my 430 but I thought maybe a different model. After pressure washing it's a 530 Model 540. There is no lift. Would it have had a backhoe on it or just a loader tractor? I has weights inside and out on the rear wheels.
The shop manual says to use ATF. Would TDH mixed with gear oil work?
