Blade Engagement & Disengagement
Cutter blades can lock-up against each other during
start-up and shut-down especially if the tractor’s PTO
engagement is
“INSTANT ON”
and
“INSTANT OFF”
.
Following Blade Engagement and Blade Disengagement
instructions below will help eliminate blade lock up.
Blade Engagement
1.
Increase throttle to a speed just enough to get the
cutter started without stalling tractor while slowly
engaging PTO drivelines. Use tractor’s PTO soft start
option if available.
2.
Ensure that all power shafts are rotating and that the
cutter is not vibrating excessively after ramping up to
PTO speed for at least 3 seconds. If excessive
vibration continues after 3 seconds at full PTO
speed, disengage PTO immediately, shut down
tractor, and remove switch key.
3.
Check blades for a lock-up situation. Block cutter
deck up before working under the unit. Unlock
blades, remove support blocks, and repeat
instructions.
Blade Disengagement
1.
Slowly decrease throttle speed until engine idle
speed is reached and then disengage PTO.
2.
Engage tractor park brake, shut tractor engine off,
and remove switch key. Stay on tractor until blades
have come to a complete stop.
Unhook Rotary Cutter
Unhook Rotary Cutter from the tractor as follows:
1.
See
on page 25 if cutter is to
be stored for a long time.
2.
Park on a level solid surface and lower deck to
ground level or onto blocks supporting the deck just
above ground level.
3.
Engage tractor park brake, shut tractor engine off,
and remove switch key. Stay on tractor until blades
have come to a complete stop.
4.
Pull back on driveline pull collar and hold while
pulling driveline yoke from tractor PTO shaft.
5.
Unhook 3-point hitch from tractor and drive tractor
forward several feet.
6.
Reinstall hitch pins, linchpins, and hair pin cotters in
cutter hitch for safe keeping.
7.
Collapse driveline by pushing tractor end of driveline
towards cutter gearbox.
8.
Rotate driveline storage hook down and place
driveline in storage hook.
Field Operation
!
WARNING
1.
Thoroughly inspect area to be cut for debris and
unforeseen objects. Mark any potential hazards.
2.
Follow
instructions on right
side of this page to start cutter blades turning.
3.
Optimum ground speed depends on density of
material being cut, horsepower rating of tractor, and
terrain. Always operate tractor at cutter’s full rated
PTO speed in a gear range that allows the cutter to
make a smooth cut without lugging the tractor down,
usually between 2 to 5 mph.
4.
Follow
instructions on right
side of this page to stop cutter blades. After the first
50 feet, disengage PTO and check to see that the
cutter is adjusted properly.
5.
Do not engage PTO when cutter is fully raised.
6.
Periodically disengage PTO, shut down tractor,
remove key, and check for foreign objects wrapped
around the blade spindle. Block cutter deck up before
removing objects.
7.
Frequently inspect cutter for loose bolts and nuts.
Tighten all loose bolts and nuts as indicated in the
“Torque Values Chart for Common Bolt Sizes”
8.

NOTE:
Periodically disengage PTO, turn off tractor,
remove key & check for objects wrapped around
blade spindle. Block deck up before removing
objects.
NOTE:
Do not cut in wet conditions. Wet material
will build up on the deck underside creating poor
discharge, high wear, and additional horsepower.
NOTE:
Frequently inspect cutter for loose bolts and
nuts. Tighten all loose hardware as indicated in the
“Torque Values Chart”
on page 32.
