Claims

[Scope of utility model registration request]

The work equipment is equipped with a soil leveling float that can be moved up and down in contact with the soil surface, and is attached to the towing vehicle body via an elevating link mechanism, and the switching valve of the hydraulic control device that operates the elevating link mechanism is connected to the work equipment. Hydraulic pressure is installed between the machine frame and the soil leveling float to move the lifting link mechanism up and down by the operation of the switching valve so that the ground pressure applied to the soil leveling float is always maintained within a certain range. In the device that operates the control device, the switching valve is supported by a support member such that it is always maintained in a vertical state with respect to the machine frame of the working machine, and is pivoted to a support frame that is pivotally supported with respect to the machine frame. A riding paddy field work machine characterized by being pivotably supported.
