When cutting large brush and small trees:
1.
Roll the front of the brush cutter up 1-2 feet (305-610mm). DO NOT LIFT THE BACK OF
THE CUTTER!
2.
Slowly drive into the tree. The front shield will raise up allowing the push bar on the
brush cutter to push against the tree. Due to the angle of the brush cutter this will allow
the blades to notch into the tree which will allow the push bar to bend the tree over and
finish the cut.
3.
If the push bar is unable to bend the tree, back up the skid steer loader and increase the
angle of the brush cutter slightly.
4.
Repeat Step #2 and #3 until the notch is sufficient (for the size of brush or tree you are
cutting) to permit the push over bar to bend the tree.
5.
When the cut is complete the remaining tree stump can be cut shorter using the brush
cutter blades or it can be easily ground down with the optional tooth kit.
6.
The tree can now be mulched by rotating the front up slightly and driving forward
several feet. Repeat, if necessary. Remember do not lift the back of the cutter.
TOOTH KIT OPERATION:
After felling large brush or small trees, position the brush cutter over the stump(s) and
using a plunging motion, grind the stump(s) down to ground level while monitoring the pressure
gauge (if so equipped) to prevent unit from going over relief. To get maximum performance,
maintain full speed of the blade carrier when grinding. To achieve this, periodically lift the cutter
off of the stump to allow the blade carrier to return to full rpm.
AVOID STALLING BRUSH CUTTER:
Continuous rotation is required to prevent overheating
of the hydraulic system. Overheating of the hydraulic system is caused if hydraulic oil is
repeatedly forced over the relief valve setting on either the prime mover or brush cutter
(whichever is less). Taking note of a maximum pressure gauge reading when the system goes
over relief on your application (prime mover and brush cutter combination) and then careful
monitoring of a pressure gauge on the brush cutter will help you prevent repeatedly forcing
your unit to go over relief and therefore causing overheating of the hydraulic system and also
stalling of the blade carrier. (Optional pressure gauge kits are available if it is not standard
equipment on your cutter.)
TO RESTART BLADE ROTATION:
Disengage auxiliary hydraulics. Remove brush cutter
from debris. Engage auxiliary hydraulics to start blade rotation. (Be sure the brush cutter
is operating smoothly and at full speed, and then start forward travel while monitoring the
pressure gauge if so equipped.)
REPEATED STALLING OF ROTATING BLADES:
Disengage auxiliary hydraulics. Remove
brush cutter from debris. Review operating conditions and the size/density of material being
cut. Make necessary corrections. Engage auxiliary hydraulics to start blade rotation. (Be sure
the brush cutter is operating smoothly and at full speed, and then start forward travel while
monitoring pressure gauge if so equipped.)
