: : What is Cub Cadet Hydrostatic Transmission Fluid? I am really getting tired of paying $7 per quart for what I suspect is ATF or hydraulic fluid. If anyone knows, please contact me. My dealer has understandably been less than helpful here!
: Local CC/ CaseIH dealer has used HyTran since dirt in CC hydros. It is equivalent to a 10w oil. ATF is lighter, most other hyd oils are heavier; similar to a 20w or 10w-30. Hi Cub Cadet Hydrostatic Transmission Fluid is, at a basic level, a 10 wt, non-detergent, oil. It has additives to prevent foaming (cavatation can ruin a hydrostat in short order), retard free moisture and maintain a stable viscosity over a wide range of operating temperatures. Temps of 180F are not uncommon in hydrostats. Most fluids have additional ingredients deemed useful by the manafacturer of the equipment it's being used in. The fact that you are purchasing fluid in such small quanities tells me that you have leaks in your system. My advice - for what's it's worth - is:
(1) That you check your lines, fittings and shaft seals for leaks, and repair them. (2) Stay with Cub Cadet Fluid, after all, the engineers that recommended it are the same ones that specified the material to be used to build the hydrostat, and chances are, they know what properties the fluid should have in order to provide you with a quality product. If you are going to change anything, it should be the supplier, you are being overcharged. Should you decide to ignore the excellent advice given by the preceding responders, be advised that the generic hydrualic oils that are on the market (The 5 gallons for 13/14 dollars, off the shelf stuff) are of inferior quality. Most of these oils have been poorly processed and have an abundance of lint and wax in them. (Vane and gear pumps can handle these oils, but the tolorances
in a hydrostat dictate that you refrain from the use of such fluids.)
