IMPLEMENT CONVERTIBLE BETWEEN USE CONFIGURATION AND TRANSPORT CONFIGURATION

摘要

The present forwardly-folding implement includes a telescoping tongue assembly, a main frame, a folding frame assembly, a rear frame assembly, left and right wing frame assemblies, and a readily replaceable toolbar assembly. The folding frame assembly is pivotally attached to the tongue assembly and to the left and right wing frame assemblies. The wing frame assemblies pivot vertically and horizontally from the rear frame assembly and optionally include powered wheel mechanisms or assist assemblies, which hydraulically pivot components of the instant implement between transport and operational configurations. When the present implement is being configured for transport, the tongue assembly is extended as the folding frame assembly and left and right wing frame assemblies are folded generally transversely to the rear frame assembly. Then, the wheel mechanisms are pivoted upwardly so that outboard portions of the wing frame assemblies are totally supported by the folding frame assembly.
