Claims7
An improved grading vehicle comprising:
- a rear vehicle section which has a rear axle and an engine;
- a front bridging vehicle chassis, one end of which is connected to the rear vehicle section, said chassis being of substantially smaller cross-section than the rear vehicle section where joined;
- front wheels mounted on the other end of said chassis;
- control equipment mounted on said chassis;
- a grading device suspended from said equipment so as to be mounted between the front wheels and the rear section of the vehicle,
- said equipment acting to adjust said grading device in all directions,
- said wheels being driven;
- and
- a universal joint for supporting the grading device which is mounted directly to the rear section at a location on said rear section spaced below where the chassis is connected to said rear section to trasmit thrust between said grading device and said rear section without tending substantially to raise the bridging chassis without simultaneous raising of the engine.
