ECO ULTRA® Tractor Hydraulic Fluid may be used in hydraulic systems alone, or in combination hydraulic-transmission systems. It is recommended for most hydraulic fluid and transmission oil applications for tractors and implements. Universal ECO ULTRA Tractor Hydraulic Fluid is specially formulated with highly re-refined Group II base oils, to be oxidation and rust resistant. Gears and bearings are protected, even in extreme applications. Its multi-viscosity ensures superior pumpability at low start-up temperatures and provides excellent service at high operating temperatures.
