PROBLEM TO BE SOLVED: To improve an operator's existing operation system conventionally requiring a complicated mechanism and electric system in a lawn mower. SOLUTION: In this operator's existing operation system, a grip member 64 of the system having a handle structure is biased by a spring member 66 toward a first position extending from a handle member 52. A switch device of the grip member 64 maintains a function of supplying and controlling a signal capable of operating a lawn-mowing unit. When the grip member 64 is moved to a position near the handle member 52 by an operator, a signal of existence of the operator is transmitted so as to activate the switch device, and therefore an operational instruction signal is transmitted to the lawn-mowing unit.
