Abstract
A linkage, especially for the pedals of a skid-steered tractor vehicle for operating the boom arms and attachment carrier, which requires no machining or threaded couplings. The arrangement includes links made of flat bar stock. Pivotal connections between adjacent links are made by punched holes, pins and side connectors. Adjustment for linear travel is at the pedal or valve rather than in the linkage itself. Crossover in the linkage path is by a bridging link having an open slot with curved sides rocking on a flat sided pin whereby movement is transmitted laterally.
