SLIP CLUTCH ADJUSTMENT (FIGURE 7)
The slip clutch is designed to slip so that the gearbox and driveline are pro-
tected if the cutter strikes an obstruction.
SHIELDING REPAIR
DANGER DANGER

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 300
feet (92m).
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.
MAN1258 (3/26/2018)
Blade Sharpening
Figure 7
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.
Remove driveline from tractor PTO.
3.
Loosen six 10 mm cap screws (6) to remove all tension from Belleville
spring plate (5).
4.
Hold clutch hub (3) solid and turn shaft to make sure clutch slips.
5.
If clutch does not slip freely, disassemble and clean the thrust plate faces
(4), flange yoke (1), and clutch hub (3).
6.
Reassemble clutch.
7.
Tighten Belleville spring (5) until it is against the thrust plate (4) of the
clutch, and then back off each of the six nuts by 2 full revolutions. The
gap between Belleville spring and thrust plate should be 3.2 mm as
shown in Figure 7.
8.
If a clutch continues to slip when the spring is compressed to 3.2 mm
gap, check friction discs (2) for excessive wear. Discs are 3.2 mm when
new. Replace discs after 1.6 mm wear. Minimum disc thickness is 1.6
mm.
