Changing the oil in the transmission and hydraulic system

Change the oil in the transmission and hydraulic system periodically.
The transmission and hydraulics share the same oil system.
1. Run the tractor until the oil in the transmission system is warm.
This speeds up the oil drainage and most of the impurities come out with the
oil.
2. Remove the drain plugs under the gearbox and final drives.
