hours.
1. With the tractor standing level and the engine off,
check the oil level with the dipstick, Figure 55.
2. The oil is at the correct level when the oil level is
between the mark and the lower end of the dip-
stick. If low, add new oil of the type specified,
page 33.
The filler plug is shown in Figure 56.
Do not fill beyond the mark on the stick, as the
transmission will be overfilled.
