Here is a quote from another site that i found. I wish someone had a VOA on this fluid to evaluate there additive package.
"Shell got back to me with a hard copy of their product data sheet for TTF-SB. They seem like really good people to deal with. I got the info from
[email protected] I posted it as best I could. Here goes... Direct from Shell:
"Code 53058 Shell TTF-SB
Shell TTF-SB is a specialized oil formulated specifically for use in lawn and garden tractors utilizing one fluid for transmissions, differentials, and hydraulics.
Product Application
Certain lawn and garden type tractors are designed to use a common fluid to lubricate the transmission, differential, and hydraulic system. This fluid must possess specific antifrictional characteristics to satisfy the friction requirements of hydrostatic transmissions, differentials, clutches, and wet brakes. The lubricant must also provide lubricity and wear protection of the gear sets and hydraulic system components. Shell TTF-SB is designed to satisfy the lubrication requirements for transmissions, differentials, and hydraulics of a wide variety of lawn and garden tractor equipment.
Product Description And Features
Shell TTF-SB is formulated with a blend of highly refined mineral oil and synthetic base fluid components and a specially designed additive package. The product possesses excellent oxidation stability, rust and corrosion inhibition, and antiwear / extreme pressure properties to protect critical components in the hydraulics, differentials, and gear sets. The product contains special lubricity / friction modifiers to satisfy certain hydrostatic transmissions and wet brake requirements. Due to the unique additive system and antifrictional properties, Shell TTF-SB does not meet the requirements of John Deere JDM J20C and D, and Caterpillar TO-4 specifications and should not be used in these applications.
Benefits
In service, Shell TTF-SB provides:
Excellent shift quality in hydrostatic transmissions
Outstanding hydraulic and gear wear protection
Excellent wet brake and clutch noise suppression
Resistance to rust and oxidation
Compatibility with seal materials used in transmission any hydraulic systems
Product Recommendations and Applications
Shell TTF-SB is approved for use in hydrostatic transmissions, differentials, and hydraulics of Hydrogear Corporation lawn and garden tractor equipment
Product Maintenance
Shell TTF-SB is designed to provide complete protection of lawn and garden tractor hydrostatic transmissions, differentials, and hydraulics. For optimum component service life, follow fluid drain schedules listed in the equipment owner’s manual.
