A cutter blade of a lawn mower includes an attachment portion, a first arm portion, and a second arm portion. The first arm portion includes a first blade portion. The second arm portion includes a second blade portion. In a horizontal placement state in which the cutter blade is placed in a manner so that a rotation center line of the cutter blade extends along a vertical direction, a position of a first portion of the first blade portion in the vertical direction and a position of a second portion of the second blade portion in the vertical direction are different from each other. A distance from the rotation center line to the first portion and a distance from the rotation center line to the second portion are equal to each other.

An internal combustion engine capable of reducing an amount of dust taken from an outside air intake opening, with a simple configuration. The internal combustion engine includes a crankshaft, a cooling air intake device that houses a cooling fan coupled to the crankshaft and that includes a cooling air intake port, and an air cleaner device that feeds outside air to an air suction port to a cylinder, and the air cleaner device includes an outside air intake opening that opens toward the cooling air intake port.

Internal combustion engine

A mower comprises: a cutter housing having an inner hole in which an output shaft of a motor is inserted; and a motor cover provided above the cutter housing with a space therebetween, the motor cover covering the motor. Cooling air leadout openings for leading cooling air in the motor cover to the outside are formed in the motor cover, the cooling air leadout openings being positioned inward of a peripheral wall part of the motor cover and outward of the inner hole of the cutter housing.

Mower with motor cooling arrangement

A lawn mower includes a blade, a motor connected to the blade, and a housing storing the blade in the housing and is configured to mow grass underneath the housing. The lawn mower includes a grass container to contain the mowed grass and a connecting member that connects the housing to the grass container. The housing is provided with a ceiling opening communicating with a flow path inside the connecting member. The ceiling opening overlaps with a region corresponding to a rotation range, of the blade, projected upward along a drive shaft.

Lawn mower

A prime mover of a mower that is a work machine comprises: a motor having a motor rotation shaft extended along a substantially vertical direction, and a motor housing disposed coaxially with the motor rotation shaft; a centrifugal fan disposed above the motor; and a motor cover that accommodates the motor and the centrifugal fan so as to extend to the upper end of a side part of the centrifugal fan. A cooling air inlet is formed in the motor housing, the centrifugal fan having a base part provided above the cooling air inlet, and the outer diameter of the base part being greater than the outer diameter of the cooling air inlet.

A cutter blade for a lawn mower has an upper blade and a lower blade. The upper blade has an upper blade base and an upper outer end positioned above and further radially outward than the upper blade base. The lower blade has a lower blade base and a mowing section positioned below and further radially outward than the lower blade base. The upper blade base overlaps the lower blade base.

The rear shield of a walk-behind lawnmower extends downward from a rear end part of a housing and is in the form of an elastic sheet. The sheet has a thin-walled part formed in a central site in a heightwise direction between an upper end part and a lower end part, the upper end part being attached to the rear end part of the housing. The thin-walled part has a thickness set to be smaller than a thickness of other parts.

A lawnmower capable of being switched between a bagging mode and a mulching mode is disclosed. The lawnmower includes a shutter mechanism provided on an internal peripheral surface of a housing which opens downward for storing a cutting blade. The shutter mechanism is switched, by the operation of the shutter mechanism, between a bagging mode for delivering cut grass from the housing to a cut grass storage container and a mulching mode for discharging the cut grass out below the housing. The shutter mechanism has a kicker on a shutter body positioned in the interior of the housing. The kicker guides the cut grass to the bottom of the housing during the mulching mode.

Shutter mechanism for a lawnmower

A lawnmower including a cut grass storage container for storing cut grass. The lawnmower also includes a cutting blade, a downwardly-opening housing, and a cut grass conveyor passage. The cut grass storage container is provided to the cut grass conveyor passage. Grass that has been cut is delivered to the cut grass conveyor passage while revolving about a shaft inside the housing. A guide member is provided inside the housing. The guide member guides the revolving grass to the cut grass conveyor passage while guiding the grass to the outer periphery of the housing.
