    摘要: The invention is a better road planing vehicle having an improved suspension system for supporting the rotary cutting unit under the vehicle chassis. The suspension includes a pair of lift and tilt cylinders connected in parallel spaced relation at one end to the vehicle frame and at the other end to the top of the cutter housing. Three parallel and triangularly arranged drawbars are connected at one end to the cutter housing and extend either fore or aft to connect at their other ends with the vehicle frame. A sideshift cylinder is connected between the frame and one of the drawbars. In the preferred embodiment the connections of the lift cylinders and the drawbars are ball joints.

    摘要: A particularly better rotary cutter for a road planing machine and the like has special holders provided with multi-sided tapered sockets extending generally tangential to the drum surface. A multiple tip cutting bit suitable for use with the aforementioned cutter has two or more tips symmetrically and equidistantly spaced about the projected centerline of an integral tapered shank. The shank has a multi-sided cross-sectional shape corresponding in arrangement to the pattern of the cutting tips, such that the bit can be indexed in its holder to place any selected one of the cutting tips in the operative position.
