Claim:
1. A tillage implement comprising: a substantially rigid main frame; a hitch coupled to and extending forwardly from a front portion of said main frame with respect to a direction of travel of the main frame; a blade gang comprising a plurality of spaced-apart blades rotatable on a common blade rotation axis; and a gang support system for coupling said blade gang to said main frame, wherein said gang support system comprises a gang angle actuator and a gang depth actuator, wherein said gang angle actuator is configured to pivot said blade gang relative to said main frame on a substantially upright gang angle pivot axis to thereby adjust the angle of said blade gang relative to the direction of travel of said tillage implement, wherein said gang depth actuator is configured to shift said blade gang upward and downwardly relative to said main frame to thereby adjust the depth of said blade gang, wherein said gang support system comprises a first support section coupled to said main frame and a second support section coupled to said first support section and said blade gang, wherein said gang angle actuator is configured to pivot said first support section relative to said main frame on said gang angle pivot axis and said gang depth actuator is configured to pivot said second support section relative to said first support section on a substantially horizontal gang depth pivot axis, wherein said gang support system further comprises a depth transfer mechanism coupled to said first support section, said second support section, and said gang depth actuator, wherein said depth transfer mechanism causes shifting of said second support section relative to said first support section when said depth transfer mechanism is shifted by said gang depth actuator, wherein said depth transfer mechanism is rotatable on a substantially horizontal depth transfer axis when shifted by said gang depth actuator, wherein said depth transfer mechanism comprises at least one depth lever arm and at least one depth adjustment arm, wherein said gang depth actuator is coupled to said depth lever arm at a location spaced from said depth transfer axis, wherein said depth adjustment arm is coupled to said second support section at a location spaced from said depth transfer axis, wherein said depth transfer mechanism comprises a depth torque bar extending along said depth transfer axis, wherein said at least one depth lever arm and said at least one depth adjustment arm are coupled to and extend outwardly from said depth torque bar.
