-12- Abstract of the Disclosure Bulldozer Assembly 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. Since the pair of spaced apart angle cylinder brackets and the universal connecting joint bracket are in general transverse alignment and the universal connecting bracket is located generally midway therebetween, any tilting of the blade permits the connection points of the pair of angle cylinders to remain generally along their neutral axis. The subject arrangement provides freedom of angling and tilting of the blade without interference between elements of the bulldozer assembly and the machine.
