COMBINED LOADER SELF-LEVELING IMPLEMENT TILT LINKAGES FOR EFFECTING TRUE LEVEL AND ENHANCED ROLL BACK AND DUMP CHARACTERISTICS THROUGHOUT LIFT RANGE OF LOADER

摘要

A front-end loader includes a pair of loader arms and features aparallelogram-shaped plate assembly associated with each arm and having first and second cornersrespectively pivotally mounted to the forward end of a respective loader arm and to animplement carrier holder and having third and fourth corners respectively pivotally coupled toleveling and tilt linkage assemblies. A tilt cylinder is mounted between the tilt linkageassembly and the parallelogram-shaped plate assembly. The parallelogram-shaped plateassembly serves to transfer leveling linkage and tilt cylinder inputs to an implement carrierholder coupled to a mounting bracket at the rear side of a bucket.
