SERVICE INSTRUCTIONS
Model MC, MD, MT, MTL
4. Check and adjust the neutral safety switch for
closure and function with the FSC in neutral (the
engine will not start when the switch is
open). Slight adjustments can be made by careful-
ly bending the leaf switch up or down as needed.
Refer to adjustment description for Safety Switch-
es in this section.
Model MS
4. Check and adjust the neutral safety switch for
closure and function with the FSC in neutral (the
engine will not start when the switch is open). Use
panel nuts on the switch body to adjust switch po-
sition for closure in neutral. Refer to adjustment
description for Safety Switches in this section.
Straight Ground Travel Adjustment - Step 4
Model MS, MC, MD, MT, MTL
1. Sit in the seat, start the engine (operate at normal
speed), and with the FSC in the NEUTRAL-PARK
position check for forward movement of either
drive wheel (if either wheel moves backward, refer
back to Neutral Function Adjustment - Step 3 and
readjust). Tighten the steering lever adjustment
nut on the side of the mower with the wheel
moving forward until wheel movement stops.
2. Check for straight ground track on a level surface
(with hands off the steering levers). Set the FSC
at several different speeds and observe if the mow-
er moves in a straight line (use cement joint or oth-
er line on the ground for reference).
NOTE: The final tracking adjustment is made with
the mower moving, since the adjustment is quite
sensitive and is more easily “fine tuned” when
moving.
3. If travel is not straight, tighten the adjustment nut
that is on the same side of the mower as the
wheel that is moving too fast, e.g., the mower
tracks to the right, indicating the LH wheel is moving
too fast, tighten the LH adjustment nut.
Straight Ground Travel Adjustment
Transmission Control - MW
IMPORTANT: The proper adjustment of the transmis-
sion control stops is essential for efficient operation
and life of the transmission. These stops are properly
adjusted at the factory and should only require readjust-
ment if the transmission or related control linkage is re-
moved or changed.
NOTE: It would not be unusual for a new machine, af-
ter initial 5 or 10 hours of operation, to begin to not trav-
el straight (this is due to the break-in of the
transmissions). In this case, proceed to Tracking Ad-
justment - Step 4.
IMPORTANT: The following adjustment procedures
are sequential. Check and adjust each function in the
order given.
DANGER
If the engine must be running to perform
a maintenance adjustment, keep hands,
feet, and clothing from moving parts. DO
NOT wear jewelry or loose clothing.
