I just purchased a Case mod.644. It runs great. The loader works fine. The hydro seems weak.Does anyone have any input if these are adjustable or if needed rebuildable?

Thanks;

Well, first of all the Case 644 is not a Hydrostatic transmission. It has a separate engine driven pump, flow control valve and motor. Case called the hydraaulic driven.

Anyway, can you define 'weakl for us? In high range it is not intended to do any work, that is transport only. But in low range it should either pull/push whatever it is hooked to or spin the tires.
