I just bought a 1650 diesel, early model, at an auction.
Tractor runs good, but has a knocking sound at the rear of the engine at medium RPM. Slow it down, the knock sound almost disapears, speed it up (around 1800 rpm) and it goes away. Oil pressure is about 38-40 psi. Almost sounds like it's coming from the Hydra drive.
Opinions? Thoughts? Could it be the hydra drive? Or do I have an engine issue?
Thanks for any input
