4-PLATE SLIP CLUTCH ADJUSTMENT (FIGURE 10)
The slip clutch is designed to slip so that the gearbox and driveline are pro-
tected if the cutter strikes an obstruction.
A new slip clutch or one that has been in storage over the winter may seize.
Before operating the cutter, make sure it will slip by performing the following
operation:
1. Turn off tractor engine and remove key.
2. Tighten four nuts (12) to remove pressure from the clutch plates (2).
Repeat for all three clutches.
3. Start tractor at low throttle and slowly engage PTO and allow clutches to
slip for 5 seconds. Disengage PTO and turn off tractor engine.
4. If clutches slip freely, completely loosen nuts (12).
5. If clutch does not slip freely, disassemble and clean plates (4, 6, & 7),
flange yoke (1), and clutch hub (3).
6. Reassemble clutch.
7. Tighten Belleville spring (5) with nuts (11) until it is against the thrust plate
(4) of the clutch. Back off each of the four nuts (11) until gap between
Belleville spring and thrust plate is 6 mm (.236 in) as shown in Figure 10.
8. If a clutch continues to slip when the spring is compressed to 6 mm (.236
in) gap, check friction discs (2) for excessive wear. Discs are 3.18 mm
(1/8 in) when new. Replace discs after 1.58 mm (1/16 in) wear. Minimum
disc thickness is 1.58 mm (1/16 in).
NOTE: When storing cutter for long periods of time, relieve the pressure on the
clutch discs by tightening the four nuts (12) on each clutch. Completely loosen
nuts (12) to return to service.

SHIELDING REPAIR

Full chain shielding must be installed at all times. Thrown objects
could injure people or damage property.
• If the machine is not equipped with full chain shielding, operation
must be stopped.
•
This shielding is designed to reduce the risk of thrown objects.
The mower deck and protective devices cannot prevent all objects
from escaping the blade enclosure in every mowing condition. It is
possible for objects to ricochet and escape, traveling as much as 92 m
(300 feet).
Repairing Chain Shielding:
1. Inspect chain shielding each day of operation and replace any broken or
missing chains as required.
2. Replace any missing hardware.
SERVICE TIRES SAFELY
Used Aircraft Tires (Figure 11)
Do not attempt to mount a tire unless you have the proper equipment and
experience to perform the job.
Always maintain the correct tire pressure. Do not inflate tires above the recom-
mended pressure. Never weld or heat a wheel and tire assembly. The heat can
cause an increase in air pressure and result in a tire explosion. Welding can
structurally weaken or deform the wheel.
When inflating tires, use a clip-on chuck and an extension hose long enough to
allow you to stand to the side — not in front of or over the tire assembly. Use a
safety cage if available.
Check wheels for low pressure, cuts, bubbles, damaged rims, or missing lug
bolts and nuts.
Never remove split rim assembly hardware (A) with the tire inflated.
