During the rst few hours of use, avoid hitting stones
as much as possible to allow the carbide teeth (A) to
wear slightly. This can be done by keeping the cutting
wheel above ground level. Brand new carbide tips are
razor sharp and can chip and shatter easily when they
hit hard objects. Once the razor sharpness has worn
away, the tips do not chip as easily. Observing these
precautions will extend the life of the carbide teeth and
reduce operating expenses.
The teeth bolts must be retighten every ten minutes for
the rst hour of use on a new mulcher.

• First, operate all functions in a clear area with skidsteer
at idle speed to get a good feel for the controls before
you actually move into any brush.
• Choose low density brush and move into it slowly, do
not expect to get the rst area done fast.
• Slow travel speed if pressure surges up close to max
psi, doing this will greatly reduce rotor jams, and with
practice, will almost eliminate jams.
• Run throttle only at half speed for rst time users.
• Operate with mulcher slightly raised until you have a
better feel how much the unit can take.
• The machine is equipped with a push bar and a felling
hook to push brush or small trees over. This will allow
the mulcher teeth to contact the lower portion of the
brush and mulch it or cut it o. The rest of the plant will
be mulched as the machine moves through the working
area.
• For tall brush, you can use the push bar to push the
brush over and cut it o close to ground. Each operator
must experiment to nd a technique that works for them
in their application.
• Although it is best to mulch when it is dry, the machine
works well in wet conditions. However, you must travel
slower to do the same quality mulching. It will also be
necessary to clean the machine more frequently to
prevent caking and clogging of the rotor area.

2. Lower mulcher so skid plates are on ground.
3. Set engine speed to low idle and engage mulcher.
4. Slowly increase engine speed to high idle. Verify
mulcher is operating smoothly and start travel.
5. If mulcher stalls, stop movement, slightly raise
mulcher and allow rotor to regain speed. Slow

6. Monitor pressure gauge closely during startup and
throughout the cutting process.
When rst starting the rotor, hydraulic pressure on
gauge will jump from zero to maximum as the motor
works to speed up the rotor. It can take up to thirty
seconds for the rotor to reach operational speed. Do
not attempt to use the mulcher before operational
speed is reached. The spinning momentum of the rotor
provides the cutting power.
As operational speed is reached, pressure will drop
to 2000 - 3000 psi. Monitor pressure gauge during
operation. Maximum cutting performance is with
hydraulic pressure between 2000 - 3000 psi.

If the rotor stalls, stop rotor motion, raise slightly and
try again.
1. If still stalled, lower unit so teeth tips dig slightly into
sod, a log or stump.
2. Reverse hydraulic ow to mulcher. Reversing
the ow does not power the rotor in the reverse
direction, it only opens the hydraulic lock on the
rotor. The rotor will not be powered in the reverse
direction.
3. Drag the rotor across sod, a log or stump in reverse
direction to dislodge the jam.
