    摘要： Disclosed is a working vehicle capable of working and driving in stable condition while suppressing the adverse effect caused by the load variation such as sudden dashing from an associated ground working implement. The working vehicle comprises a controller for controlling the variator ratio of its toroidal mechanism to oppose the variation of the load when the toroidal mechanism is loaded on its output side. The controller adjusts the variator ratio appropriately when the engine starts.

    摘要： Provided is a riding lawn mower having good operability while securing safety even in backward movement traveling. In a riding lawn mower including a working machine 4 provided on a traveling vehicle body 1 and a forward and backward movement detection unit 94 configured to detect a forward movement operation or a backward movement operation of the traveling vehicle body 1. A control unit 100 is provided with a backward movement vehicle speed limit mode for limiting a vehicle speed when the working machine 4 is driven and the backward movement operation is detected. A traveling motor 30 that drives drive wheels 3 of the traveling vehicle body 1 is provided. The vehicle speed is limited by limiting a rotational speed of the traveling motor 30 to a predetermined value or less when the vehicle speed is limited in the backward movement vehicle speed limit mode. A vehicle speed limit release switch 105 configured to disable the backward movement vehicle speed limit mode is provided. The control unit 100 includes an acceleration value control unit configured to release a limit of the vehicle speed when the vehicle speed is limited in the backward movement vehicle speed limit mode and the vehicle speed limit release switch 105 is operated and control the vehicle speed so that an acceleration value does not exceed a certain value.
