Refer to Figure 6-5: for Ditch Bank Mount
The speed increaser is mounted between the tractor
power take-off shaft and hydraulic pump. It is used to
increase power take-off speed from 540 rpm or 1000 rpm
to approximately 2000 rpm at the pump.
Check oil level by removing the level plug. Oil level should
be level with bottom of level plug hole. If oil is below the oil
level hole, remove fill plug and add recommend oil
through the fill plug hole. When completed, reinstall level
plug and fill plug. Tighten both plugs to prevent oil
leakage.
Change oil after the first 100 working hours. Thereafter,
make successive changes every 1500 hours or every
year, whichever comes first. Remove drain plug to drain
oil. Be sure to reinstall drain plug and tighten before filling
the gearbox. Fill gearbox with 80-90W EP gearlube to the
recommended amount provided in box below. When
completed, reinstall level plug and fill plug. Tighten both
plugs to prevent oil leakage.
