ABSTRACT:
A two-way bulldozer mechanism for mounting on an earthmoving vehicle includes an upper blade having an upper edge pivotally connected to the forward tip portions of a pair of push arms for pivotal movement thereabout and a lower blade hingedly connected to a lower edge of the upper blade for limited relative rotational movement to permit the attitude of the upper and lower blades to be adjusted to a first position suitable for forward bulldozing to a second position suitable for rearward dozing. A pair of levers have their intermediate portions pivotally connected to the push arms with each of the levers having its lower end pivotally connected to the lower blade and cooperates with the upper blade for controlling the attitude of the blades. A pair of hydraulic cylinders are mounted on the push arms with each hydraulic cylinder having an extensible and retractable piston rod pivotally connected to the upper end of one of the levers whereby extending the piston rods pivots the levers to position the lower and upper blades in the first position and retracting the piston rods pivots the levers to position the upper and lower blades in the second position.
