Fill Gearbox
NOTICE
■ Gearbox is not filled at the factory. Prior to
delivery, make sure each gearbox is filled half-full
with 80W or 90W API GL-4 or GL-5 gear lube.
1. Make sure vent plug hole 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 or GL-5.
2. Fill gearbox until oil runs out the side plug on
gearbox.
3. Pour in one pint of gear lube, wait five minutes and
add additional gear lube until it just comes out of
side hole.
4. Allow an additional five minutes for the lube 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)
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).
1. Install chain shielding plate (3) to rear mower frame
as shown.
2. Secure with carriage bolts (14) and flanged lock
nuts (15).
Insert carriage bolts from bottom upward as
shown.

and two SAE flat washers (4) between roller
bracket as shown in Figure 34.
