A high quality, multifunctional, extreme pressure fluid to meet the service top-up and refill needs of transmissions, final drives, hydraulic and power-steering systems and fluid immersed disc brakes of virtually all farm and industrial tractors and mobile equipment, especially where many components must be satisfied with a fluid from a common source i.e. oil sump or oil reservoir. Engen Agrifluid has a viscosity approximating that of SAE 10W-30 engine oil along with a high viscosity index to minimise viscosity changes with changing temperatures. It is extremely stable even in severe high-temperature torque-converter use and has excellent anti-wear properties. Frictional properties are designed to assure proper, decisive functioning of multi-disc clutches used in some transmission designs requiring a limited slip function and in oil immersed disc brakes.
