The neutral and mow switches are attached to the function control lever bracket
under the console cover; refer to

control lever is in the N
normally open proximity switches that close when the actuator comes in close
proximity to the switch. If the function control lever is moved out of N
neutral switch opens) when the parking brake is engaged or the operator is not
in the seat, the engine magneto will divert the ignition circuit to ground and the
engine will stop. Both of the switches and the actuator are adjustable.

the engine is off and the key switch is in the OFF position.
2. Remove the console from the right side of the operator seat.

switch by connecting a multimeter (ohms setting) across the switch terminals.

mow switch should be open (no continuity between the switch terminals).
