Abstract: It is desirable in many applications to have a bulldozer assembly that can be angled and/or tilted without having interference between elements of the bulldozer assembly and the machine on which it is mounted. In the subject arrangement, a bulldozer assembly has a blade connected to a U-shaped frame through a universal connector. The blade is angled by a pair of angle cylinders connected between the U-shaped frame and a pair of spaced apart angle cylinder brackets located on the blade. The universal connector is connected to the blade generally midway between the pair of spaced apart angled cylinder brackets and generally aligned therewith. The pitch of the blade is maintained at a preselected position by a pitch control mechanism and mechanically adjusted by the pitch control mechanism.

Abstract: An implement assembly (12) includes an implement (16), such as a blade (22) of a work vehicle (10), connected to a frame (14) through a pivot connection (23) for pivotally supporting the blade (22). The blade (22) and frame (14) are closely positioned to the front of the work vehicle for maximum stability and balance of the vehicle (10). A first apparatus (18) tilts the blade (22) generally vertically and a second apparatus (20), such as fluid cylinders (40,42), moves the blade (22) to selected angular positions relative to the vehicle (10). The pivotal connection (23) has first, second, and third pivot axes (127,129,131) which allows the blade (22) to tilt and angle in various combinations without binding of the blade (22). A subframe (50) is pivotally connected to the frame (14) and to the second apparatus (20). The blade (22) moves along the subframe (50) during tilting, and with the subframe (50) during angling.

Abstract: An implement assembly (12) includes an implement (16), such as, for example, a blade (22) of a work vehicle (10), pivotally connected to a frame (14) for supporting said blade (22). The blade (22) and frame (14) are closely positioned to the front of the work vehicle (10) for maximum stability and balance of the vehicle (10). In the implement assembly (12) first apparatus (18) tilts the blade (22) generally vertically. Second apparatus (20), such as, for example, angling cylinders (40,42), moves the blade (22) to preselected angles relative to the vehicle (10). A subframe (50) is pivotally connected to the frame (14) and second apparatus (20). The blade (22) moves along the subframe (50) during tilting and with the subframe (50) to the preselected angles.

Abstract: A stabilizing linkage for a material handling implement such as a bulldozer blade mounted at one end of a vehicle, the linkage including a coupler link pivotably connected to the bulldozer blade and extending diagonally between the blade and vehicle with control links of different lengths being pivotably interconnected between the coupler link and the vehicle, an additional coupling restraining movement of the other end of the coupler link relative to the vehicle.
