Claim:
1. An agricultural tillage implement, comprising: a main frame section including a pull hitch tube extending in a travel direction, said pull hitch tube having a forward end and a rearward end; at least one wing section pivotally coupled with said main frame section about at least one generally vertical axis located at said rearward end of said pull hitch tube, said at least one pivotally coupled wing section operable to pivot forward about said at least one generally vertical axis to a position adjacent to and generally parallel with said pull hitch tube when in a transport configuration, said at least one pivotally coupled wing section operable to pivot outward about said at least one generally vertical axis to a position perpendicular to said pull hitch tube when in an operating configuration; at least one wing front shank frame pivotally attached to said at least one pivotally coupled wing section, said at least one wing front shank frame operable to pivot to a generally vertical position when in said transport configuration and operable to pivot to a generally horizontal position when in said operating configuration; at least one stand-off bracket attached to said at least one pivotally coupled wing section and extending perpendicularly from said at least one pivotally coupled wing section in a forward direction when said at least one pivotally coupled wing section is in said position perpendicular to said pull hitch tube in said operating configuration, and extending perpendicularly from said at least one pivotally coupled wing section in a laterally inward direction when said at least one pivotally coupled wing section is in said position adjacent to and generally parallel with said pull hitch tube in said transport configuration; at least one pivoting swing arm being pivotally connected with said at least one stand-off bracket, said at least one pivoting swing arm being operable to pivot inward towards said at least one pivotally coupled wing section when in said transport configuration and to pivot forward towards said forward end of said pull hitch tube when in said operating configuration; at least one draft member being coupled between said at least one pivoting swing arm and said forward end of said pull hitch tube; and a controller for controlling said at least one pivotally coupled wing section, said at least one wing front shank frame, and said at least one pivoting swing arm, said controller operable to reconfigure the agricultural tillage implement from said operating configuration to said transport configuration by a folding sequence of steps, said folding sequence of steps comprising:
