Abstract
An angled bulldozer blade for an earthmoving machine is operatively connected to a slider assembly slidably carried on a rail fastened to each side arm of a C-frame. Removable pins engage with each slider assembly and pass into aligned apertures of a plurality of prelocated apertures in the rail to position the slider assembly for setting the blade in a desired angled position. Self-locking latches are provided for retaining the pins in position. Eight apertures in each side rail are located so as to provide five positions for the slider assembly.
