Circuit Breakers
Depending on model, either one or two manual reset
circuit breakers are located on the instrument panel.
Each has a button that pops out if the circuit breaker
trips. For Models MT, MTEFI and MTLEFI, the 7 amp
circuit breaker protects the safety circuits and GHS.
For Model MTL, the 7 amp circuit breaker protects
the warning lights/horn, safety circuits and GHS. For
Model MTL, the 10 amp circuit breaker protects the
headlights. For Model MT, the 30 amp circuit breaker
(located near the battery) protects the instrument
panel and headlights. For Model MTL, the two (2) 30
amp circuit breakers protect the instrument panel,
starter solenoid and ’fan’ control module. For Models
MTEFI and MTLEFI, the 30 amp circuit breaker pro-
tects the instrument panel, headlights, and starter
solenoid, and a 20 amp fuse protects the ECU.
STARTING THE ENGINE
1. Before attempting to start the engine, make
sure the operator is in the seat, the Forward
Speed Control is in NEUTRAL-PARK position,
and the blade clutch and parking brake are
DISENGAGED.
NOTE: Release parking brake to prevent extra
load on the starter if the transmission neutral is
slightly out of adjustment.
NOTE: For starting in cold weather [below 40° F
(4° C)], use the optional cold start lever to release
the jackshaft drive belt and remove the hydrostatic
transmission from the starter cranking load. After
the engine has been started and warmed up, lower
the lever to re-engage the jackshaft drive belt.
Optional Cold Start Lever
2. For Model MT and MTL, move the choke lever to
the ON position and move the throttle 1/4 to 1/2
open (toward FAST). Turn the ignition switch to
the START position to start the engine. Release
the key to RUN position as soon as the engine
starts.
NOTE: For Model MT and MTL, the choke
may not be required if the engine is warm.
IMPORTANT: If the engine fails to start after
approximately 10 seconds of cranking, the en-
gine should be checked before further cranking.
Turn the key to the OFF position and allow a
60 second cool-down period between starting
attempts. Failure to follow these guidelines can
damage the starter motor and shorten battery
life. Consult your Walker dealer or Authorized
Kohler dealer for additional help.
CAUTION
Before operating the mower, read and un-
derstand all Safety Instructions and Operat-
ing Instructions.
WARNING
NEVER run the engine in an enclosed or
poorly ventilated area. Engine exhaust
contains carbon monoxide, an odorless
and deadly gas.
CAUTION
A safety interlock switch system PRE-
VENTS CRANKING the engine with either
the Forward Speed Control or the blade
clutch (PTO) out of neutral. If the engine
cranks otherwise, the safety system is not
working and should be repaired or ad-
justed before operating the mower. DO
NOT disconnect safety switches; they are
for the operator’s protection.
