SERVICE AND MAINTENANCE
Your riding mower 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 riding mower running efficiently and to reduce
fire risk is to regularly remove debris buildup from the riding mower. Follow the
recommendations below and contact your authorized dealer with any questions.
•
Allow the riding mower to cool in an open area before cleaning.
•
Do not use water on any part
of the riding mower. Doing
so can cause damage to the
riding mower’s electrical
components and motor. The
use of compressed air and/or
leaf blower or a brush, damp
sponge or rag will help keep
the riding mower clean.
•
Clean around fuses and
wiring harnesses.
•
Clean the top of the riding
mower deck. See Figure 15.
•
Clean around and near the
transmission and axle. See
Figure 16.
•
Debris can accumulate
anywhere on the riding
mower, 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 riding mower before operating and storing, do
not attempt to mow unusually tall grass (10” or higher), dry grass (e.g.,
pasture) or piles of dry leaves. Dry grass or leaves may build up on the riding
mower 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.
Front Axles:
Each end of the riding mower’s front pivot bar may be equipped with a grease
fitting. Lubricate with a grease gun after every 25 hours of operation.
Rear Wheels:
The rear wheels should be removed from the axles once a season. Lubricate the
axles and the rims well with an all-purpose grease before re-installing them.
Pivot Points & Linkage:
Lubricate all the pivot points on the drive system, parking brake and lift linkage at
least once a season 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 riding mower’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)
It is possible to adjust the pitch of the cutting deck. The front of the deck should
be between 0” (level) and 1/4” (6.4 mm) lower than the rear of the deck. Adjust if
necessary as follows:
1.
With the riding mower parked on a firm, level surface, place the deck lift
lever in the middle position and rotate the blade so that it is aligned with the
front and rear of the riding mower.
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 end of the blade facing the front of the deck
should be between 0” (level) and 1/4” (6.4 mm) less than the end of the blade
facing the back of the deck. Determine the approximate distance necessary for
proper adjustment and proceed, if necessary, to the next step.
3.
Locate the flange lock nut (a) on
the front end of the PTO lift rod
(b). See Figure 17.
a. Tighten the flange lock
nut (a) to raise the front
of the deck.
b. Loosen the flange lock
nut (a) to lower the
front of the deck.
Parking Brake Adjustment
If the riding mower does not come to a complete stop when the brake pedal is
completely depressed, or if the riding mower’s rear wheels can roll with the parking
brake applied, the brake is in need of adjustment. See your authorized service
dealer to have the brake adjusted.
Neutral Adjustment
If the riding mower creeps forward or rearward when neither the forward nor
reverse pedal is depressed, contact your local authorized dealer to have the neutral
setting properly adjusted.
Seat Adjustment
Refer to the Assembly section of this manual for seat adjustment instructions.
Service
Deck Removal
To remove the cutting deck,
proceed as follows:
1.
Power off the riding
mower, remove the key
from the key switch, and
engage the parking brake.
2.
Lower the deck by moving
the deck lift lever into the
lowest (#1) position on the right fender.
3.
Remove the bow-tie cotter pin (a) and flat washer (b) from the deck lift
assembly and retain for reinstallation later. See Figure 18.
