ABSTRACT:
A unique and improved loader design is disclosed incorporating straight lift arms and channeled front wheels. The front wheels define a channel or groove through which the lift arms are allowed to intercept unobstructed. The lift arms pivotally join a bucket positioned at the front of the loader with a pair of uprights positioned at the rear end of the loader. The channeled front wheels may be formed from two ordinary tires joined in tandem and separated by a spacer or by using molded, grooved, elastomeric tires. The design eliminates the highly stressed joint found in ordinary two-piece lift arm loaders. Fabrication is simplified and manufacturing costs are reduced.
