RC2512 Series 2 S/N Rotary Cutters 330-725M
Inspect Field and Cutter Blades
1.
Thoroughly inspect area to be cut for debris and
unforeseen objects. Remove all potential hazards
and mark any that cannot be removed.
Refer to Figure 3-4:
2.
Inspect wing blade carriers and cutting blades for
locked blades prior to lowering the wings. Use a pry
bar or other tool to separate locked blades.

Lower Wings Down & Set Cutting Height
Refer to Figure 3-3 on page 28:
1.
Start tractor and raise both wings up to release any
tension on transport locks (#3).
2.
Without lowering cutter, shut tractor down properly
before dismounting. Refer to
3.
Remove hairpin cotters (#1) from both left and right
wing cylinder pins (#4).
Refer to Figure 3-2 on page 28:
4.
Rotate end of transport locks (#3) up to storage
lugs (#2). Secure with hairpin cotters (#1).
5.
Start tractor and lower both wings down.
6.
Adjust cutter to field cutting height. See
on page 24 for detailed
instructions.
Set Wing Lift Lever In Float Position
Use the float position of your tractor’s hydraulic system to
provide automatic floating of the wings for varying terrain
conditions. This will ensure that the wing gauge wheels
are in continuous contact with the ground at all times.

Select Gear Range
Optimum ground speed depends on density of material
being cut, horsepower rating of tractor, and (in some
cases) terrain. Always operate tractor at cutter’s
full-rated power take-off 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. Loss of power
take-off speed will allow the blades to hinge back and
result in ragged, uneven cutting.
Engage Blades
1.
Select a gear range that will allow the cutter to make
a smooth cut without lugging the tractor down.
See
on page 29 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 power take-off
drivelines. Use tractor’s power take-off soft start
option if available.
3.
Ensure all drivelines are rotating and that the cutter is
not vibrating excessively after ramping up to 540
power take-off speed for at least 3 seconds. If
excessive vibration continues after 3 seconds at full
540 power take-off speed, disengage power take-off
immediately, shut down tractor, and remove switch
key. Wait for blades to come to a complete stop
before dismounting tractor.
4.
Investigate the cause if cutter was shut down due to
excessive vibration. See
on page 27 for detailed instructions.
5.
If cutter was not shut down, commence forward
cutting operation at full power take-off 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 50.
Disengage Blades
1.
Slowly decrease throttle speed until engine idle
speed is reached.
2.
Disengage power take-off.
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.
