Field Set-up

WARNING

The following operational procedures should be carried out

by the tractor operator. Other persons should be cleared of the

area. All cutter operations including field set-up should be

stopped when other persons are in the vicinity.

Lower Wing Down & Set Cutting Height

Refer to Figure 3-5:

1. Inspect wing blade carriers and cutting blades prior

to lowering the wings.

Wing Deck Blade Positioning

Figure 3-5

Refer to Figure 3-3 & Figure 3-4 on page 25:

2. See Figure 3-4. Fully raise both wings up to release

any tension on the transport lock bars. Remove

hairpin clip (#1) from transport lock pin (#2).

3. See Figure 3-3. Swing transport lock bar (#3) to

stored position and over lock pin (#2). Secure with

hairpin clip (#1).

4. Repeat steps 2&3onother wing.

5. Lower wing sections to down position.

6. Adjust cutter to field cutting height. See “Cutting

Height Adjustment” on page 21 for detailed

instructions.

Set Wing Lift Lever In Float Position

IMPORTANT: Cutting blades may become locked

together (overlapped) when wings are raised for

transport. Operating cutter in this condition will

result in severe deck vibration. Inspect wings for

locked blades prior to power-on operation. Use a pry

bar or other tool to separate blades.

IMPORTANT: The wing folding lever should be in

float position to avoid damage to the wing hydraulic

cylinder and axle while cutting on uneven terrain.

IMPORTANT: Do not operate this cutter under any

terrain conditions where, on a continuous cut, the

wing hinge angle exceeds 45 degrees up. Damage

to the wing driveline and gearboxes can occur.

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 “Select Gear Range” 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.

4. Investigate the cause if cutter was shut down due to

excessive vibration. See “Blade Operation

Inspection” on page 22 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, turn off tractor, remove

switch key & check for objects wrapped around blade

spindles. Block deck up before removing objects.

7. 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 PTO.

3. Place tractor in park or set park brake, shut tractor

engine off, remove switch key, and wait for blades to

stop before dismounting from tractor.

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.
