ABSTRACT:
An apparatus for mounting a dozer blade for vertical and angular movement relative to a frame of a wheeled implement. The mounting apparatus a mounting mechanism which allows the dozer blade to be mounted close to the wheels to either end of the implement and which permits angular movement of the blade about a generally vertical axis and vertical movement of the dozer blade about a generally horizontal axis. The mounting apparatus further includes a linearly distendable driver which extends laterally across the frame of the implement and a linkage mechanism which improves angling moments and maximizes the driving force imparted to the blade upon extension of the driver. The linearly distendable driver and linkage mechanism operate in combination and in a closely confined area adjacent to the implement frame for effecting extended angular movement of the dozer blade.
