One circuit is the ignition switch and the other contanis

The fi xed deck midsize mowers use three different
electrical systems. All are intended to ensure a safe
condition when starting and prevent the operator from
leaving the operator zone with the machine in an unsafe
condition. The difference in the systems is due to the
type of controls on each model.
