摘要： A clippings collecting-discharging device saves labor in an operation for discharging collected clippings. The clippings collecting-discharging device includes: a bucket on a lawn mowing unit divided into a main body part including a clippings flow inlet and a movable part connected to an upper end of the main body part, and can be operated between a closed position where the main body part and the movable part abut against each other and an open position where the movable part is rotated upward and separated from the main body part; a discharge plate in the bucket positioned near the inlet in a lying posture when the bucket is closed; and a discharge mechanism where the discharge plate stands up toward an opening, between the main body part and the movable part while interlocking with the operation of the bucket, which position is changed to the open position.

摘要： A lifting device lifts and lowers the working unit with respect to an axis of wheels as a center and can move the wheels of the working unit aloft. The lifting device applies to a lawn mowing vehicle comprising a lawn mowing unit and a main body. The lawn mowing unit includes drum wheels that are rotatable about an axis Ax1 extending in a vehicle width direction. The main body is connected to the lawn mowing unit so as to be rotatable about the axis Ax1 and immovable in the axis Ax direction, and can travel with the lawn mowing unit. The lifting device includes a first support member at the lawn mowing unit, a second support member at the main body, and a linear actuator that includes a retractable rod having a front end portion and a main body part having a rear end portion.
