    'Tractor Fluid' for Ford N or John Deere- HyTrans? Look for the 303 on label, get a useful for geared transmission and hydraulic use- the HyTans means hydraulic and transmission fluid, good multivis oil with some zinc for gear shear and good flow for moderate pressure hydraulic systems with 3 point hitch, lift cylinders. Ford N needs a heavier oil, AC used a high pressure, low flow hydrualic system and something closer to GL5 works better than thin HyTrans that is also often spec for garden tractor with hydrostat transmission that are servicable, have filters. Not good for the sealed sustran units that will fail at 250 to 400 hours without service- and the service means on Big Box store units actual removed, invert and refill, replace- a 3 to 4 hour job without shop equipment unlike the expensive commercial units that have drain plugs, canister filters that can be changed quickly- some even have spin on filters using a common small GM filter or Toyota filter. 303 in 5 gallon buckets used in skid steers at times.

    Well, if you were to walk into an ordinary auto parts store and ask for "tractor fluid" they're probably going to look at you funny.

    Tractor fluid is a much more complex fluid than plain hydraulic fluid and contains specific additives to control friction, protect gears, prevent rust, protect seals and prevent foaming.
