Connection:
8. Slip clutch is incorporated
in the PTO driveline. It is de-
signed to slip, absorb the shock
load, and protect the driveline. Af-
ter the first hour of operation, the
slip clutch should be checked for
overheating. After this first
check, the slip clutch should be
checked weekly or anytime there
is overheating. To adjust the slip
clutch, tighten the spring bolts 1/8
(maximum) turn at a time. Bolts
should NEVER be adjusted to the
point where the springs are com-
pressed solid. Minimum spring
length is 1-1/8". The slip clutch
should be checked periodically
and adjusted to compensate for
wear. The lining plates are 1/8"
thick when new. Replace after 1/
32" wear. If the mower has been
idle for an extended period of time,
or in wet weather, before operat-
ing check to be sure the friction
lining plates are not frozen or
rusted together. Should this
freezing occur refer to the proce-
dure described in the "Seasonal
Clutch Maintenance" section on
the next page. There are four fric-
tion lining plates in the slip clutch.
These should be checked weekly
for oil or grease, wear, and mois-
ture which could cause corrosion
on the drive plates. (See Figure 7)
