ABSTRACT:
Top link assemblies for a construction machine are typically used to adjust the pitch angle of a cutting edge of a blade. The present top link assembly has substantially co-planar first and second adjustment plates with each including a pair of slots therein. Joint upper and lower surfaces are defined between the first and second adjustment plates. Upper and lower spacer plates are disposed on the joint upper and lower surfaces, respectively, and each include a pair of openings coaxially aligned with the slots within the first and second adjustment plates. A threaded portion of a bolt extends through the upper spacer plate, first and second adjustment plates and lower spacer plate through the co-axially aligned openings and slots. A nut is tightened on the threaded portion at any one of a plurality of positions along the pair of slots and the desired pitch angle of the cutting edge may be adjusted by loosening the nuts and repositioning at any one of the plurality of positions. The ability to adjust the pitch angle without removing the top link assembly increases productivity and decreases costs.
