Changing oil in the hydraulic system

Both hydraulic and transmission oil can be used in the hydraulic system. The use
of transmission oil is recommended, since hydraulic oil may mix with oils from
other tractors through implements and thereby damage other tractors. The
hydraulic system is filled with transmission oil at the factory.
