Tractor TDH — UTTO Tractor Lubricant

Tractor TDH by Kelpen Oil is the transmission lubricant designed for modern agricultural tractors in which the gearbox, the differential, the wet disc brakes and the hydraulic system share a common fluid — while the engine runs on its own oil (typically a heavy-duty diesel lubricant such as Vita Truck).

Formulated within the UTTO (Universal Tractor Transmission Oil) specification, Tractor TDH delivers:

• Optimized protection for gearbox and differential gears.
• Controlled friction for wet brakes and clutches — no chatter, no torque loss.
• Stability for hydraulic pumps and implement cylinders.
• Compatibility with seals and elastomers used in the integrated systems of agricultural tractors.

With SAE 10W30 viscosity and a high-refining mineral base, it suits farms that clearly separate engine lubricant (Vita Truck) and transmission/hydraulic lubricant (Tractor TDH).

Applications

• Tractor transmissions with integrated differential gearbox
• Axles with wet disc brakes
• Hydraulic systems of tractors and implements
• Agricultural forklifts

Advantages

• Specialized UTTO formulation — better performance than a STOU for tractors that separate the engine.
• Optimized friction for wet brakes and wet clutches — no chatter, no torque loss.
• Compatible with most agricultural OEMs that recommend UTTO.
• Nationwide availability from Kelpen Oil, with 27 years of expertise in the lubricant market.
