A knotter table of a baler includes a plurality of tucker finger assemblies which each aid in tying together ends of a set of twine strands so as to tie a loop of twine about a bale formed in a baling chamber. Each tucker finger assembly includes a tucker finger defined by a plate pivotally mounted alongside a baling chamber needle slot for being pivoted horizontally between a standby position, wherein the tucker finger is entirely to one side of the needle slot, and a working position, wherein the tucker finger is pivoted across the needle slot. A stop arrangement is provided for being engaged by the tucker finger or by an operating linkage coupled to the tucker finger in the event that the tucker finger pivots a preselected distance beyond a desired working range so as to prevent the operating linkage from going over-center and causing linkage damage.
