PROBLEM TO BE SOLVED: To provide a control lever mechanism for a riding-type grooving implement, surely eliminating trouble, such as, accidentally traveling in a high speed when turning, ensuring its traveling speed to be put under control at discretion in conducting a normal grooving operation, thus having such a reasonable construction as to enable grooving operations to be conducted in a safe and swift manner. SOLUTION: The control lever mechanism has a single control lever (62), disposed so as to lie near its steering handle (40) and subjected to shared use for the throttle divergence control for an engine (15) and for turning the power transmission from the engine (15) to driving wheels (12) on/off, wherein the control lever (62) is designed so that its control part (65), set up on its free end side, can take such a low-speed control position as to be swung from its idling position to the handle (40) side and gripped at the same time as the handle (40) and such a medium-high-speed control position as to be further swung from the low-speed control position by the fingers of the operator's hand gripping the handle (40).
