If I'm reading my manual right, my 641 uses M4864A, which is about SAE 80 or 90. I think that my hydraulic reservoir is filled with UTF, which would not be the correct weight for this tractor. I'd like to ask a few questions about this.
A. I've noticed that my 3-pt lift moves very quick, and is hard to make fine adjustments. Is this because of the lighter fluid?
B. Will using UTF cause any adverse effects on the tractor?
C. I can't find M4864A anywhere. What would be a suitable replacement for this fluid?
