Abstract
The invention relates to a traveling mower including a traveling bodywith a mower unit, and a grass collection boxfor storing the mowed grass. The box is pivotally connected to the traveling body for switching between a grass collection posture for receiving grass and a discharge posture for discharging grass. The bodyis provided with a posture change lever. The boxand the leverare associated with each other via an interlock mechanismso that the boxchanges the posture in accordance with the manual operation of the lever. The change of the posture of the boxis performed with a small operation force that depends on the amount of the grass in the box. To enable this, the interlock mechanismincludes a switching mechanism for increasing the turning angle of the box, per unit operation of the lever, when the boxis empty or substantially empty and for reducing the turning angle when the boxholds much grass.
