•
Some tractors are equipped with two power take-off speeds.
Be certain your tractor’s power take-off shaft is set-up to
operate at 540 rpm. Do not exceed 540 rpm power take-off
speed or equipment breakage may result.
•
Do not use implement for a purpose other than the work it
is designed to do as defined in this manual.
•
Do not use implement as a man lift or work platform. It is
not properly designed or guarded for this use.
•
Do not use implement to lift objects; to pull objects such as
fence posts, stumps, etc; or to push objects. The unit is not
designed or guarded for these uses.

Transporting
DANGER
!
To avoid serious injury or death:
Always disengage power take-off before lifting implement up,
and never operate implement in the raised position. Objects
can be thrown at high speeds toward people or animals.
WARNING
!
To avoid serious injury or death:
•
Select a safe ground speed when transporting. Never travel
at a speed which does not allow adequate control of steering
and stopping, and never exceed 20 mph (32.2 km/h) with
attached equipment. Rough terrain requires a slower speed.
•
When traveling on public roadways, travel in such a way
that faster moving vehicles may pass safely. Use accessory
lights, clean reflectors, and a slow moving vehicle sign that
is visible from the back to warn operators in other vehicles
of your presence. Always comply with all federal, state, and
1. Select a safe ground speed when transporting from
one area to another. Maximum transport speed for
the Stump Grinder is 20 mph.
DO NOT EXCEED
.
2. Be sure to reduce tractor ground speed when turning
and leave enough clearance so the Stump Grinder
does not contact obstacles such as buildings, trees,
or fences.
3. When traveling on roadways, transport in such a way
that faster moving vehicles may pass you safely.
4. Shift tractor to a lower gear when traveling over rough
or hilly terrain.
Stump Grinder Operation
DANGER
!
To avoid serious injury or death:
•
Keep bystanders and animals away from machinery while
in operation. They can become entangled in the equipment,
hit by throwing objects, or ran over.
•
Never make contact with underground utilities such as
electrical power lines, gas lines, phone lines, etc. They can
cause serious injury or death from electrocution, explosion,
or fire. If in doubt, call 811 (USA) before digging so that
they can mark the location of underground services in the
area. For contact information, see Dig Safe in the
“Important Safety Information” starting on page 1.
•
Keep bystanders away from rotating teeth. They can be
injured or entangled by the rotating teeth.
WARNING
!
To avoid serious injury or death:
Clear all debris from stump area before operating unit. Keep
all bystanders at a safe distance away from product being
discharged. Wood chips and debris can discharge at high
speeds causing serious injury or death.
1. Be sure to read and understand all safety alerts
2. Check for overhead and below ground obstructions
before grinding the stump.
Refer to Figure 3-1 on page 25:
3. Fully retract lift cylinder (#1) and swing cylinder (#2).
4. Position the cutting wheel on the far left side of the
stump as shown.
5. Lower hitch down until the Stump Grinder frame is
firmly planted on the ground.
6. Extend lift cylinder (#1) until the cutting teeth are just
above the stump as shown in Figure 3-2 on page 25.
7.
Engage power take-off and use swing cylinder (#2) to
move cutting wheel to the right as shown in
8. Slightly extend lift cylinder (#1) to lower the carbide
teeth enough to make a cut into the stump as shown
IMPORTANT:
Do not move tractor forward or
rearward while Stump Grinder is removing wood
chips. Doing so can damage components.
NOTE:
Rate and depth of cut is determined by
sharpness of the rotary teeth, density of the wood,
and condition of the wood.
