Do not operate the mower without plugging the
mower’s wiring harness into the seat switch. This
switch is an important part of the safety start
interlock system. Serious injury can result if the
seat switch is not plugged into the mower’s wiring
harness.
Never operate the mower with a non-functioning
seat switch. Always reconnect the seat switch to the
mower harness.
Never operate the mower with the seat platform
improperly secured. The seat platform must be
securely latched/bolted to prevent the seat from
moving/tilting in the event of mower tipping or
rollover.
