ABSTRACT:
An apparatus for permitting the pitch of a dozer blade to change automatically during blade use includes a blade member including a housing having a housing wall and a blade attachment portion. An anchor member including a rod is telescoped to the housing and has a rod attachment portion and a retainer attached to the rod. A compression spring is in the housing and exerts force on the wall and the retainer. The rod and blade attachment portions are thereby urged closer to one another and the blade is automatically tipped rearwardly to a "semi-carry" position. During digging with the blade lower edge, the spring allows the blade to tip forwardly. A method for automatically adjusting the blade pitch is also included.
