Lower Wing Down & Set Cutting Height
Refer to Figure 3-3:

Inspect wing blade carriers and cutting blades prior to
lowering the wings.

Refer to Figure 3-2 & Figure 3-1 on page 25:
2.
Raise both wings up to release any tension on the
transport lock bar as shown in Figure 3-2. Remove
hairpin clip (#1) from both the left and right cylinder
pins (#4).
3.
Rotate end of transport lock bar (#3) to the storage
pin (#2) as shown in Figure 3-1. Secure with hairpin
clips (#1).

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 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. Loss of PTO 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
above 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 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. 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 24 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.
Periodically, disengage PTO, stop tractor, place gear
selector in park or set park brake, turn off tractor,
remove switch key and wait for blades stop rotating
before dismounting tractor.
7.
Dismount tractor and check for objects wrapped
around blade spindles. Block deck up before
removing objects.
8.
Daily inspect cutter for loose bolts and nuts. Tighten
all loose hardware as indicated in the
“Torque
Values Chart”
on page 50.
