1 INTRODUCTION
Congratulations on your choice of a Baumalight
Brush Mulcher to complement your mulching
operation. This equipment has been designed and
manufactured to meet the needs of a discriminating
buyer for efcient mulching of brush.
The rotor is hydraulic powered by the hydraulic
system on your skidsteer.
Replaceable bearings are provided at major pivot
points for extended service life.
Safe, efcient and trouble free operation of your
brush mulcher requires that you and anyone
else who will be operating or maintaining the
brush mulcher, read and understand the Safety,
Operation, Maintenance and Troubleshooting
information contained within the Operator’s
Manual.
This manual covers the Baumalight 900 Series
Brush Mulchers. Use the Table of Contents as a
guide to locate required information.
Keep this manual handy for frequent reference
and to pass on to new operators or owners. Call
your Baumalight dealer, distributor or the factory
if you need assistance, information or additional
copies of the manuals.
When this machine is worn out and no longer in
use, it should be returned to the retailer or other
party for recycling.
OPERATOR ORIENTATION - The directions left,
right, front and rear, as mentioned throughout this
manual, are as seen from the skidsteer driver’s
seat and facing in the direction of travel.
1�1 Overview
The brush mulcher is designed to be used
by experienced operators, trained in the safe
operation of a skidsteer and trained in the hazards
related to using the brush mulcher and the safe use
of the mulcher for the intended purpose. Operators
will require personal protective equipment to
reduce the risk from some hazards that cannot be
completely eliminated or controlled by the design
of the tool.
Care is required to ensure that the brush mulcher
tool will not come across metallic objects, stones
or other materials.
Brush mulcher tools are not designed for use in
hazardous atmospheres where there is a risk
of re or explosion due to ammable gases or
vapors. Use in hazardous, explosive atmospheres
is prohibited.
Serious injury or death of the operator or bystanders
may be caused if the tool is misused. Misuse may
also cause damage to the machine carrying the
implement.

5�4 Attach To Skidsteer
^WARNING
To prevent injury or machine damage
put transmission in “Park”�
Never position yourself between
skidsteer and brush mulcher�
Only experienced and properly trained
operator’s should operate the skidsteer
and brush mulcher�
1. Read and follow all safety instructions.
2. Attach mulcher to skidsteer. See skidsteer
Operator’s Manual.
3. Verify pins are secure in the correct position.
4. Connect hydraulic hoses. Verify hydraulic
hoses are clear of pinch areas and moving
parts.
5. Move to a clear open area to test functions
5�5 Detach From Skidsteer
^WARNING
Prevent serious injury or death caused
by unexpected movement:
1� Park skidsteer on a level surface�
2� Engage skidsteer park brake�
3� Disconnect hydraulic drive�
4� Shut off engine and remove key�
1. Park skidsteer on a level surface.
2. Lower mulcher to the ground.
3. Shut off engine and remove key.
4. Disconnect hydraulic hoses.
5. Detach mulcher from skidsteer. See skidsteer
Operator’s Manual
15

5�6 Transporting
1. Verify all reectors and Slow Moving Vehicle
(SMV) sign are visible.
2. Raise brush mulcher slightly off ground.
3. Verify hydraulics are disengaged.
4. Travel at a reasonable and safe speed.
^WARNING
To prevent bodily injury from rotating
cutting wheel, be sure to disengage
hydraulics before transporting mulcher�
5�7 Carbide Teeth Break-In
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.

5�8 First Time User Tips
• 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 off. 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 off 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.
^WARNING
Always turn off the skidsteer and
disengage hydraulic drive before
getting off the seat and approaching the
cutting wheel�
