Abstract

The power equipment such as a lawn mower () comprises an internal combustion engine () having a plurality of cylinders, an engine control unit () for selectively deactivating at least one of the cylinders, a work implement such as a cutting blade () connected to the engine in a power transmitting relationship, a clutch () provided in a power transmission path between the engine and the work implement, and a central control unit () for controlling an operation of a propelling device, the clutch and the engine control unit. The central control unit is configured to start the engine with two or more of the cylinders activated, to cause the engine control unit to operate the engine at a prescribed rotational speed, and to cause the engine control unit to deactivate at least one of the cylinders when the engine has reached a stable state at the prescribed rotational speed.
