Drum Mulcher Operation and Maintenance Manual
Operation
Drum Stall
NOTE: If the rotation of the cutting drum stops
due to jammed up debris in the cutting
chamber, promptly shut down hydraulic
flow to the mulcher to avoid hydraulic oil
overheating.
Causes and Remedy
• Operator induced.
• Lift head to recover.
• Debris jammed up in cutting chamber.
• Immediately shut down hydraulic flow to the
mulcher.
• Press the head’s rotating drum against the
ground.
• Drive the machine in reverse, dragging the
head on the ground, to force the drum to
turn backward and dislodge jammed up
debris until the drum turns free.
• In extreme cases, blockage must be
manually removed.
WARNING
AVOID SERIOUS INJURY OR DEATH
Before servicing the attachment:
• Always park on a flat level surface.
• Lower lift arms and place attachment flat
on the ground.
• Place all controls in NEUTRAL.
• Engage the park brake.
• Wait for all moving parts to stop.
• Relieve hydraulic system pressure.
• Stop the engine and remove the key.

FOR ADDITIONAL INFORMATION.
Grease Overflow
Below each of the three grease zerks is a grease
overflow port. Grease overflow during operation
may occur.
NOTE: If the grease overflow is liquid, it may be a
sign of bearing overheating or the
operating temperature of the grease used
is too low.
Vibration
NOTE: Do not operate with an unbalanced cutting
drum. The resulting vibration can cause
severe damage to the mulcher and the
machine.
IMPORTANT
Mulchers are known to generate
tremendous vibrations when the cutting
drum becomes unbalanced. The resulting
vibration will reduce the life of all
mechanical and structural systems of both
the mulcher head and the machine. Do not
operate with an unbalanced cutting drum.
