Relays
Relays operate in coordination with each
switch and component, and are installed to
control each electrical device ON/OFF.
Important
Do not install relays that differ to the specified
relays.
Doing so may result in damage to the
electrical circuit.
Relays are located under the seat, and 11
relays are used.
Note:
Different types of relays are used depending
on the machine model.
#10001 - 10027: 4 types
#10028-: 5 types

Relay Operation
Relay 1/Seat switch
Operates in coordination with the off delay
timer related to the seat switch, and is one
of the parts that controls engine start,
driving, and stop.
Relay 2/Stop solenoid
Operates with other relays when specific
conditions are met, to ensure safety.
Connected to the fuel cut solenoid and
controls engine driving and stop.
Relay 3/reel rotation
Operates in coordination with the reel
rotation switch, and is one of the parts that
controls engine start, driving and stop, and
reel cutter rotation.
