Abstract

Crawler track means are mounted on and adapted to carry the frame of the machine and have a tread having a rear end. A loader is mounted on and protrudes forwardly beyond the forward end of said frame and has a scooping lip which has the configuration of an arrowhead and is formed with forward edges defining a plane. The loader is forwardly and downwardly inclined toward the scooping lip and is adapted to be raised and lowered relative to the frame and crawler track means and adapted to assume a lowermost position. When the loader is in said lowermost position, said plane defined by said forward edges of said scooping lip is tangent to said crawler track means behind the center of the length of said crawler track means and spaced from said tread before the center of the length of said crawler track means.
