Lower Wing Down & Set Cutting Height
Refer to Figure 3-2 & Figure 3-3 on page 35:
1.
Start tractor and raise both wings up to release any
tension on transport lock bar as shown in Figure 3-3
on page 35. Remove hairpin clip (#1) from both the
left and right cylinder pins (#4).
2.
Without lowering cutter, shut tractor down properly
before dismounting. Refer to
3.
Rotate end of transport lock bar (#3) to storage
pin (#2) as shown in Figure 3-2 on page 35. Secure
with hairpin clips (#1).
4.
Start tractor and lower both wing sections down.
5.
Adjust cutter to field cutting height. See
on page 30 for detailed
instructions.
Set Wing Lift Lever In Float Position
Use float position of your tractor’s hydraulic system to
provide automatic floating of wings for varying terrain
conditions. This will ensure 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 blades to hinge back and result
in ragged, uneven cutting.
IMPORTANT:
The wing folding levers should be in
float position to avoid damage to the hydraulic
cylinders and axles while cutting on uneven terrain.
IMPORTANT:
Do not let the wings flex down more
than 20 degrees while operating the cutter. Doing so
can cause damage to the cutter.
Engage Blades
1.
Select a gear range that will allow cutter to make a
smooth cut without lugging tractor down.
See
instructions.
2.
With wings lowered, increase throttle to a speed just
enough to get cutter started without stalling tractor
while slowly engaging power take-off. Use tractor’s
power take-off soft start option if available.
3.
Ensure all power shafts are rotating and that the
cutter is not vibrating excessively after ramping up to
power take-off speed for at least 3 seconds. If
excessive vibration continues after 3 seconds at full
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 cause if cutter was shut down due to
excessive vibration. See
on page 34 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.
Periodically, disengage power take-off, stop tractor,
place gear selector in park or set park brake, turn off
tractor, remove switch key and wait for blades to 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”
Disengage Blades
1.
Slowly decrease throttle speed until engine idle
speed is reached.
2.
Disengage power take-off.
3.
Place tractor in park or set park brake, shut tractor
engine off, remove switch key, and wait for blades to
come to a complete stop before dismounting from
tractor.
