Abstract: The cutter unit of a lawn maintenance machine may include: a shaft; and an even number of cutter blades aligned in a left-right direction extending from the first portion away from a rotation axis. Each of the even number of cutter blades may be attached to the shaft in one of the at least three postures. A number of the cutter blades disposed to a right of a center position may be same as a number of the cutter blades disposed to a left of the center position. A disposition of the cutter blades in the right-left direction as viewed from the center position toward the right may be same as a disposition of the cutter blades in the right-left direction as viewed from the center position toward the left. The postures of two cutter blades being at a same distance from the center position may be same.

Abstract: A lawn maintenance machine may include: a pair of wheels configured to rotate on a ground; a handle unit configured to be gripped by a user while the lawn maintenance machine is moving; a working unit configured to work on the ground; an electric motor configured to drive the working unit; a fan configured to rotate by operation of the electric motor; a housing configured to support the working unit and housing the electric motor and the fan; and a wall disposed outside the housing and attached to the housing. The housing may have a connection opening which connects an inside and an outside of the housing and through which air flows by a rotation of the fan. The wall may be disposed to face the connection opening.

Abstract: A lubricating device for an engine is provided. A first opening part penetrates a first partition wall separating a crank chamber and an oil sump chamber. A second opening part penetrates a second partition wall separating the crank chamber and a valve drive chamber. In a lubricating device for an engine, when the pressure in the crank chamber is positive, gas in the crank chamber is injected into the oil sump chamber through the first opening part and impacts oil, thus generating mist oil in the oil sump chamber, and mist oil in the crank chamber passes through the second opening part and is supplied to the valve drive chamber, whereas when the pressure in the crank chamber is negative, mist oil in the oil sump chamber passes through the first opening part and is supplied to the crank chamber.

Abstract: The first opening part penetrates the first partition wall that separates the crank chamber and the oil sump chamber. The lubricating device of the engine includes an oil mist generation control part. The oil mist generation control part disperses gas injected from the crank chamber into the oil sump chamber through the first opening part when the crank chamber has a positive pressure or restricts the flow of oil with which the injected gas collides, thereby controlling an amount of oil mist generated in the oil sump chamber.

Abstract: A power-operated work apparatus has a machine body which includes an electrostatic charge inducing member that may induce electrostatic charges thereon, and is adapted to be used with the machine body maintained electrically ungrounded. The work apparatus includes: a grip which is adapted to be grasped and held by a user and has an outer surface to be touched by the user and an inner surface forming an inner space; an electroconductive body member which forms an electroconductive body exposed on at least a part of the outer surface of the grip; and an electroconductive line member which is configured to be charged with the electrostatic charges induced on the electrostatic charge inducing member and has a part disposed inside the grip neighboring to and without electrically touching the electroconductive body forming member. The electrostatic charges are to spark from the electroconductive line member to the electroconductive body member.
