Engage Blades

IMPORTANT: Cutter blades can lock-up against
each other during start-up and shut-down especially
if tractor's PTO engagement is "INSTANT ON" and
"INSTANT OFF". Follow Blade Engagement and
Blade Disengagement instructions to help eliminate
blade lock up.
1. Select a gear range that will allow the cutter to make
a smooth cut without lugging the tractor down.
See "Select Gear Range" on page 19 for detailed
instructions.
2. With wings lowered, 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.
3. Ensure that all drivelines are rotating and that the
cutter is not vibrating excessively after ramping up to
540 PTO speed for at least 3 seconds. If excessive
vibration continues after 3 seconds at full 540 PTO
speed, disengage PTO immediately, shut down
tractor, and remove switch key.
4. Investigate the cause if cutter was shut down due to
excessive vibration. See "Blade Operation
Inspection" on page 17 for detailed instructions.
5. If cutter was not shut down, commence forward
cutting operation at full PTO operating speed. Make
a new gear selection if tractor is lugging down or if
cutter is making a rough cut.
6. Frequently inspect cutter for loose bolts and nuts.
Tighten all loose hardware as indicated in the
"Torque Values Chart" on page 40.

Disengage Blades

1. Slowly decrease throttle speed until engine idle
speed is reached.
2. Disengage PTO.
3. Stay on the tractor until the blades have come to a
complete stop. Always place tractor in park or set
park brake, shut tractor engine off, and remove
switch key before dismounting.

Unhooking The Rotary Cutter

1. See "Long Term Storage" on page 29 if parking
cutter for long periods and end of season.
2. Disengage PTO, park cutter on a level solid hard
surface. Place tractor gear selector in park, and set
park brake.
NOTE: Center deck will raise fully up before wing
cylinders will start to fold wings up.
3. Wait for blades to come to a complete stop and then
fold wings up to transport position before
dismounting from tractor.
4. Lock wings in transport position with transport lock
bars. See "Setting Transport Locks" on page 18.

height.
6. With tractor gear selector in park and park brake set,
shut tractor engine off and remove switch key. Move
cylinder lift levers back and forth to release hydraulic
line pressure.
Refer to Figure 3-6:
