SERVICE AND MAINTENANCE
Front Wheels
Each of the front wheel axles and rims is equipped with a grease fitting. See Figure
17 for the location of the grease fitting on the axles and Figure 18 for the location of
the grease fitting on the rims. Lubricate with a No. 2 multi-purpose grease applied
with a grease gun after every 25 hours of operation.
Deck Wheels
The wheels on the deck which are spherical in shape are equipped with a grease
fitting. Lubricate with a No. 2 multi-purpose grease applied with a grease gun after
every 25 hours of operation.
Pivot Points & Linkage
Lubricate all the pivot points on the drive system, parking brake and lift linkage
every ten hours with light oil.
Note: It is not necessary to grease the steering pinion/sector gear interface. Doing
so will allow dirt to accumulate and can affect steering performance.
Adjustments
WARNING
Before making adjustments, always disengage the PTO, set the
parking brake, turn key to OFF position and remove to prevent
unintended starting. Protect your hands by using heavy gloves when
handling the blades.
Note : Check the tractor’s tire pressure before performing any deck leveling
adjustments. Refer to Checking Tire Pressure in the Assembly Section for
information regarding tire pressure.
Adjusting the Deck
Leveling the Deck (Front-To-Rear)
The front of the deck is supported by a
stabilizer bar that can be adjusted to level
the deck from front to rear. The front of the
deck should be between 1⁄4” (6.4 mm) and
3⁄8” (9.5 mm) lower than the rear of the
deck. Adjust if necessary as follows:
1. Park the tractor on a firm, level
surface and place the deck lift
lever in the middle position
and rotate the blade nearest
the discharge chute so that it is
parallel with the tractor.
2. Measure the distance from the
front of the blade tip to the ground and the rear of the blade tip to the
ground. The front of the blade should be between 1⁄4” (6.4 mm) and 3⁄8”
(9.5 mm) less than the rear of blade.
3. Determine the approximate distance necessary for proper adjustment and
proceed, if necessary.
4. To raise the front of the deck, loosen the outer nut then tighten (thread
inward) the nut against the front hanger bracket. See Figure 19. When
proper adjustment is achieved, re-tighten the outer nut to 25–30 ft.–lbs
(33.9–40.7 N–m).

Cleaning the Tractor
WARNING
If the tractor has been recently run, metal surfaces will be hot and can
cause burns to the skin. Let the tractor cool for at least five minutes
Exercise caution to avoid burns.
Your tractor should be cleaned after each use and under certain conditions, i.e. dry
conditions and/or mulching situations, additional cleaning may be necessary.
One of the best ways to keep your tractor running efficiently and to reduce fire risk
is to regularly remove debris buildup from the tractor. Follow the recommendations
below and contact your authorized dealer with any questions.
• Allow the tractor to cool in an open area before cleaning.
• Do not use water on any part of the tractor. Doing so can cause damage to
the tractor’s electrical
components and motors.
The use of compressed
air and/or leaf blower or
a brush, damp sponge
or rag will help keep the
tractor clean.
• Clean around fuses and
wiring harnesses.
• Clean the top of the tractor
deck. See Figure 15.
• Clean around and near
the transmission and
axle. See Figure 16.
• Debris can accumulate
anywhere on the
tractor, especially on
horizontal surfaces.
Additional cleaning
may be necessary
when mowing in dry
conditions or when
mulching.
• Excess lubrication can
become collection
sites for debris. Immediate repair and cleaning up excess lubrication can help
reduce fire hazards.
• In addition to cleaning the tractor before operating and storing, do not
attempt to mow unusually tall grass (10” (25.4cm) or higher), dry grass (e.g.,
pasture) or piles of dry leaves. Dry grass or leaves may build up on the tractor
deck presenting a potential fire hazard.
Lubrication
DANGER
Bearing failures and overheating can result in fire. Always follow
the instructions in this manual regarding lubrication locations and
intervals. Contact your authorized dealer with any questions about the
lubrication locations and intervals or any unusual noises coming from
any areas a bearing may be located.
WARNING
Before lubricating, repairing, or inspecting, always disengage the PTO,
set the parking brake,turn key to OFF position and remove to prevent
unintended starting.
