    Abstract: Work equipment configured to unload a collected article from the storage container and resistant to tipping over when unloading the collected article. The work equipment includes a vehicle body; a storage container provided on the vehicle body so as to be moveable between a horizontal position for storing a collected article and an inclined position for unloading the collected article; a drive unit provided between the vehicle body and the storage container and configured to change a container inclination angle defined as an angle of the storage container with respect to the vehicle body; an inclination angle sensor detecting a vehicle body inclination angle defined as an inclination angle of the vehicle body with respect to a horizontal plane; and a control unit configured to control a driving operation of the drive unit according to the vehicle body inclination angle.

    Abstract: The configuration includes: a motor for driving a driving wheel (rear wheel) provided to a body; a slip ratio calculating section for calculating a slip ratio while the lawn mower is traveling; a friction coefficient calculating section for calculating a friction coefficient of a ground on which the lawn mower is traveling; a determination section for determining whether the ground on which the lawn mower is traveling is a lawn based on a relationship between the slip ratio and the friction coefficient and a drive controlling section for controlling the motor based on a determination result from the determination section. This configuration allows suitable driving operability for both of a case where the ground on which a lawn mowers traveling is a lawn and a case where the ground is other than a lawn.

    Abstract: Uneven distribution of grass clippings in a grass clippings receptacle of a lawn mower can be minimized. A lawn mower includes: a work unit including a housing having a downward-facing opening and a cutter blade rotatably provided in the housing such that the cutter blade cuts grass and generates a transport air flow flowing from the opening of the housing to inside; a grass clippings receptacle configured to receive mowed grass clippings; a grass clippings transport passage connecting an interior of the housing with the grass clippings receptacle; a shutter device including a shutter configured to open and close the grass clippings transport passage and an actuator configured to open/close-drive the shutter; a controller configured to control the shutter device; and a speed sensor for detecting a travel speed of the lawn mower, wherein the controller is configured to open/dose-control the shutter device based on the travel speed.

    Abstract: A lawn mower includes a housing, a drive source, flaps, a grass clippings container, a grass clippings container weight detection unit, an internal pressure detection unit, and a control unit. If it is determined that a first condition where a change amount per predetermined fixed time of the weight detected by the grass clippings container weight detection unit is below a weight change amount reference value and a second condition where a change amount per predetermined fixed time of the internal pressure detected by the internal pressure detection unit has increased to a internal pressure change amount reference value, are satisfied, the control unit implements control to place the flaps in a substantially horizontal state.
