A hydraulic pressure gauge on mulcher is visible
from operator’s seat and indicates hydraulic system
pressure.
If gauge approaches maximum pressure, slow
ground speed or raise mulcher slightly so mulcher is
not operating at maximum operating pressure for an
extended period of time.
Operating at maximum pressure can shorten the life
of hydraulic components. Operating at slightly below
maximum pressure will allow for better productivity and
more ecient operation.

The push bar is used for pushing over brush and small
trees when mulching, not for pushing over standing
trees.
