MULCHER HIGH ENOUGH THAT YOU SEE THE SAFETY CHAINS. IF THE
SAFETY CHAINS ARE VISIBLE DEBRIS CAN BE DISCHARGED BACK
TOWARDS THE OPERATOR CAUSING SEVERE BODILY INJURY OR DEATH.
GROUND SPEED:
Ground speed can be determined by watching the pressure gauge and slowing
down whenever the gauge approaches maximum operating pressure. Operating at ground speed that
is too fast will cause the rotor to engage too much material and stall. As you slow down the ground
speed and reduce the amount of material going through the mulcher the pressure gauge will go down.
NOTE:
Excavator’s must be stationary during mulching operations. Do not mulch while the excavator
is in motion.
STALLING:
If the attachment stalls, the operator will have to stop and remove the mulcher from the
material and allow the rotor to regain speed. Slow down your ground speed to prevent further stalling
on skid steer loader applications and reduce the load on the mulcher on excavator applications.
JAM:
When a jam occurs, shut off the hydraulics. Move the mulcher to a clear area, set the mulcher
down and drive in reverse to force the drum to rotate without hydraulics and therefore discharging the
jam. Setting the center of the rotor down on a log or felled tree and driving in reverse will help to clear
even the biggest
jams.
BRUSH:
Skid Steer Loader:
When clearing brush set the skid shoes down and travel forward through the brush
at a pace that will not decrease the rotor rpm. Once you are completely through, stop and travel back
over the brush in reverse. This will re-mulch the brush and produce a more finished surface.
Excavator:
When clearing brush, start at the top and using a sweeping action, swing the unit back and
forth through the brush while lowering at a pace that will not decrease the rotor rpm. Once you are
completely through the brush, continue sweeping, this will re-mulch the brush and produce a more
finished surface.
NOTE:
Traveling too fast will not properly mulch the material.
TREES:
Skid Steer Loader:
Start at the trunk with the mulcher tilted back slightly and the deflector door open
(if so equipped). When you are half way through the tree, tilt the mulcher forward and use the push
over bar to push the tree over. Grind down the remainder of the trunk to prevent the prime mover from
getting “hung up”. Position the mulcher on top of the tree and travel forward removing the limbs. Lower
the unit and travel back and forth over each section of the trunk until gone. This may take many passes
depending on the diameter of the tree.
Excavator:
Start at a safe operating height for your excavator and cut off the top of the tree. Position
the mulcher over the tree trunk and slowly lower the mulcher.
CAUTION!
TAKE EXTRA CARE WHEN MULCHING DEAD STANDING TREES. THERE IS A
DANGER OF THE TOPS FALLING BACK ONTO THE OPERATOR’S CAB,
CAUSING INJURY OR PROPERTY DAMAGE.
GROUND MULCHING / MIXING:
The mulcher head is capable of mulching and mixing debris
approximately 1.50” below ground level. Keep in mind that excessive ground engaging will rapidly
decrease the life of the cutting teeth, sometimes up to as much as 50%. When doing excessive ground
engaged mulching, inspect the cutting teeth more often to ensure the teeth are not worn to the point
that the holders are wearing down also.
