WARNING
The following operating procedures must be carefully read
and fully understood. You are the tractor operator and are
therefore responsible for the safe operation of this unit. All
other persons must be cleared of the area. Cutter operation
must be stopped when in the vicinity of other persons.
11. After attachment to the tractor, carefully raise and
lower the cutter to ensure that the drawbar, tires,
and other equipment on the tractor do not contact
the cutter frame or PTO shaft.
12. Check all hoses and wires to be sure that they will
not contact the PTO shaft. PTO guards must be in
good condition and in place.
13. When the deck is in the transport position, and the
PTO disengaged, check to be sure the blades are
not locked (overlapped) together. The deck safety
chain must be engaged in the deck hook provided.
14. Check blades for sharpness and ensure that both
blade bolts as well as the center blade carrier hub
nut are tight. Check tractor safety equipment -
particularly the ROPS (Roll Over Protective
Structure) and the operator safety screen to be
sure both are in good working condition. Wear your
safety glasses.
15. Remove and stow the deck safety chain just prior to
cutting. Adjust lower 3-point links such that the
PTO shaft is approximately level. Extend the
cutters parallel arms out and position the deck flat
on the ground.
16. Increase tractor throttle to approximately 500 RPM
and slowly engage the PTO. Initial start-up
vibration is normal, but should stop after a few
revolutions of the blade carrier. If vibration
continues, stop PTO rotation. Wait for the blade
carrier to come to a complete stop before
dismounting from the tractor, then check the blades
to be sure they are not locked together.
17. Once the cutter is running smooth increase tractor
throttle to provide for 540 PTO RPM.
18. Position the cutter deck for best operator visibility.
This is normally with the arms extended to
approximately 3/4 of full extension. Adjust deck
attitude and height. Optimum ground speed will
depend on the density of the material being cut,
operator awareness, and (in some cases) terrain. If
in doubt, reduce tractor ground speed to a
comfortable level.

WARNING
Do not operate this cutter under any terrain conditions that
would place the tractor at an angle exceeding 30 degrees
either front-to-rear or left-to-right. Ensure that adequate
ballast weights are provided on both the front of the tractor
and left of the tractor and left hand side of cutter to assure
tractor stability. See Figure 6-1.
Breakaway Operations
This cutter is designed for breakaway of the cutter
head and parallel arms in the event the cutter head
contacts an immovable object or irregular terrain
during forward tractor movement. The “breakaway” will
prevent structural damage to the cutter head, parallel
arms, and mainframe in the event of such contact. See
Figure 6-2.
Upon breakaway, the cutter head must be reset to the
original "home" position before normal cutting
operations can be resumed. Reset to the home
position is accomplished somewhat differently
depending on whether the cutter is equipped with the
standard tension bolt or the optional breakaway
(hydraulic) cylinder.
Tension Bolt
1. Raise the arms and deck upward to clear any
obstacles located behind the cutter deck.
2. Slowly back the tractor and cutter away from those
obstacles that would interfere with rotating the
deck and arms back to the “home” position.
!
WARNING
Shut off PTO power, put the tractor in park and wait for the
blades to stop rotating before dismounting from the tractor.
IMPORTANT: If a 1000 RPM tractor PTO is being
used, engine RPM MUST be reduced to limit PTO
RPM to 540. Excessive engine speed will cause
damage to the speed increaser and other power
train components.
