A clutch mechanism is selectively transmitting rotation of the handle to a blade assembly elevating mechanism and a blade assembly inclining mechanism. The elevational position and the inclination of the blade assembly are adjusted in accordance with the rotation of the handle assembly. A rack is secured to the support frame and the handle assembly is moved along the rack to a predetermined angle position. A lock lever is disposed in operative association with the handle assembly and operatively connected to the clutch mechanism. The lock lever serves to lock the support member to the predetermined angle position and is provided with a cam mechanism through which operation of the clutch mechanism is changed. |
