FOR ADDITIONAL INFORMATION.
WARNING
Drum Wrapping
Debris such as rope, wire, roots, plastic etc.
may wrap around rotaing drum. STOP
IMMEDIATELY and remove foreign material.
Spinning of drum and throwing of material
may cause harm to operator/bystander!
Stopping the Drum Mulcher
Position the drum mulcher slightly off the ground.
Set the machine’s engine RPM to an idle, allow
the drum mulcher to slow down, disengage the
auxiliary hydraulic flow (see the machine’s
operator’s manual) to the drum mulcher.
Allow the time for the drum to stop rotating and
lower the drum to the ground.
Stop the engine.
Mulcher Functions
Gate
The optional mulcher gate pushed down produces
a finer mulch and can be used to help control
debris ejection out of the cutting chamber.
Push Bar
The optional hydraulic push bar is essential for
tree felling control; among other uses, it is
generally used to push a standing tree forward
while cutting the base.
Push bar horizontal extensions are used to nudge
a falling tree over sideways to control the direction
of the fall.
Cutting Drum Variable Speed
The cutting drum is most efficient at high speed
(1800 to 2400 rpm).
When hydraulic system pressure reaches the
hydraulic motor shift point, the cutting drum speed
drops in torque mode and becomes ineffective.
Lift the head up and allow cutting drum to regain
speed.
Mulching Techniques
Mulching techniques vary from regions,
vegetation types, conditions and operators
preferences. The following is an overview of the
more common techniques.
