Harris Ferguson TO-30

[Just 1 More]

I have an old 1950-1953 Harris Ferguson TO 30 tractor. What gear lube do I use in the transmission gear case. The gear case is all connected to the rear axle drive gears also,, and the PTO shaft which runs off the axle gears. Do I use a 90w, regular hydrolic oil, or what?

I have 1961 MF 35 and from what I have been told by dealers and other owners is that 90-100w Mineral oil is the recommended Hydraulic oils for older MF Tractors. Stay away from Universal tractor fluid because they are too thin and contains parrafins or waxy additives that can clog up older pump systems.
