Abstract:
1. A tillage implement comprising: a mobile frame; a first pair of elongated, non-overlapping, generally end-to-end gang assemblies supported by the frame, each of said gang assemblies including a plurality of rotatable tillage tools mounted in such a manner that their axes of rotation extend generally transverse to the path of travel of the frame, said gang assemblies being horizontally adjustable in mutually opposite directions relative to said frame about respective upright pivot axes for adjusting the angles between the path of travel of the frame and said axes of rotation of the tools; a pair of hydraulic actuators operably coupled with respective ones of said gang assemblies in a manner for effecting said angular adjustment of both gang assemblies simultaneously; and synchronizing apparatus operably interconnecting said gang assemblies for synchronizing the gang assemblies during said simultaneous angular adjustment by said pair of hydraulic actuators such that both gang assemblies are angularly adjusted by the same amount but in opposite directions, said synchronizing apparatus comprising a pair of intermeshing gear segments at opposed, proximal ends of the pair of gang assemblies.
