Fill Gearbox
1.
Make sure vent/dipstick hole plug is clear. Fill
gearbox half-full with high quality gear oil that has a
viscosity index of 80W or 90W and an API service
rating of GL-4 and GL-5.
2.
Fill gearbox until oil runs out of the side plug on
gearbox.
3.
Pour in one pint of gear oil, wait five minutes and
add additional gear oil until it just comes out of side
hole.
4.
Allow an additional five minutes for the oil to flow
through bearings, then check to make sure oil level
is at bottom of side hole. Replace side plug. Install
vent plug.
Install Chain Shielding (Optional)
1.
Install chain shielding plate (1) on top rear edge of

Figure 33
. Chain Shielding Installed
Full chain shielding must be installed when
operating in populated areas or other areas where
thrown objects could injure people or damage
property.
• If this machine is not equipped with full chain
shielding, operation must be stopped when any-
one comes within 300 feet (92 m).
• This shielding is designed to reduce the risk
of thrown objects. The mower deck and protec-
tive 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 (92 m).
• Check that chain shielding is in good condi-
tion and replace any damaged chain links.
Install Front Roller (Optional)
1.
Install three carriage bolts (8) through front roller
bracket (2) as shown in Figure 34. Install flanged
lock nuts (9) loosely. Do not tighten.
2.
Align roller bracket (2) with keyhole slots in the
front of the mower deck. Pass head of carriage
bolt thru round hole and slide toward square end of
keyholes. Tighten flanged lock nuts (9) to 35 lbs-ft.
3.
Place roller (1), spacer (3), bearings (4), and
washers (5) in roller bracket as shown in Figure 34.
4.
Insert cap screw (6) through bracket and roller.
5.
Secure with flanged lock nut (9). Do not
overtighten; roller must spin freely.
