Abstract

A skid steer front-end loader includes a body comprised of a pair of similar body sections, each being formed from a single blank of material. Each body section includes a side wall, a bottom wall portion and a front wall portion. The bottom wall and front wall portions of the body section are disposed in lapped relation and are bolted together after each body section has been preassembled. The cab structure, including a floor plate, a back plate and a roof, are secured to the body and project rearwardly therefrom to position the operator completely rearwardly of the loader body.

Claims

1. A compact skid steer front-end loader comprising:

a body including a pair of substantially similar body sections, each section including a vertical, substantially flat side wall, each having a vertical rear edge, a substantially flat bottom wall portion integral with and having a length corresponding to the length of the associated side wall, each section including a substantially flat front wall portion integral with the associated side wall and bottom wall portion, each front wall portion having a vertical dimension less than the vertical dimension of the associated side wall and having a width dimension corresponding to the width dimension of the associated bottom wall portion,

the bottom wall portions and front wall portions of said sections being disposed in lapped relation, and being fixedly secured together,

a pair of substantially flat, upstanding boom support plates, each affixed to one of said side walls adjacent the rear of and projecting upwardly therefrom,

a boom assembly pivotally connected to the boom support plates and projecting forwardly therefrom, an implement pivotally mounted on the forward end of said boom assembly, means for pivoting the boom assembly about its pivot axis, and means on the boom assembly for pivoting the implement relative thereto,

front and rear pairs of ground-engaging wheels supporting said body for travel over the surface of the ground, means for driving said ground-engaging wheels,

said rear ground engaging wheels being positioned forwardly of the rear vertical edge of each side wall,

a cab structure including a floor plate, a back plate integral with said floor plate and extending upwardly therefrom, means connecting said cab structure to the rear portion of said body, whereby said cab structure is positioned rearwardly of the body, and rearwardly of said ground engaging wheels and said boom support plate.

2. The skid steer loader as defined in claim 1 and a pair of tank-defining structures affixed to each body section and defining therewith a closed tank containing drive components for each pair of ground-engaging wheels, said tank-defining structures being positioned interiorly of the side walls of each body section.

3. The skid steer loader as defined in claim 1 and an operator'"'"'s seat pivotally mounted on the back plate of said cab structure.

4. The skid steer loader as defined in claim 1 wherein each of said boom support plates has a substantially straight rear vertical edge disposed in substantial vertical alignment with the rear vertical edge of the associated side wall.
