ABSTRACT:
The lift arms and linkage arrangement for the bucket of a loading machine includes first and second spaced apart lift arm assemblies and first and second spaced apart linkage assemblies associated with respective lift arm assemblies. The first and second lift arm assemblies diverge with respect to the centerline of the machine while the first and second linkage assemblies are parallel to the centerline of the machine. The first and second lift arm assemblies are closer to each other at the machine end than at the bucket end. This provides greater visibility of the corners of the bucket for the machine operator and more precise positioning of the bucket by the operator.
