Tillage implement with auxiliary rollers

A tillage implement comprising:

• a frame connectable to a towing vehicle, the frame comprising a plurality of elongated transverse frame elements and a plurality of elongated longitudinal frame elements connected to the plurality of elongated transverse frame elements, the frame having a horizontal longitudinal axis parallel to a direction of travel of the tillage implement and a horizontal transverse axis perpendicular to the horizontal longitudinal axis when the tillage implement is in a deployed configuration to till a field;
• at least two transverse rows of secondary tillage tools mounted on the frame, the at least two transverse rows comprising a row of main rollers mounted on the frame rearward of all other rows of the at least two transverse rows;
• a transverse row of auxiliary rollers mounted rearward of the row of main rollers, the transverse row of auxiliary rollers independently pivotable vertically about an auxiliary roller transverse pivot axis;
• at least one ground-engaging wheel, and
• at least one auxiliary roller row actuator connecting the row of auxiliary rollers to the frame, whereby pivoting of the row of auxiliary rollers is caused by actuation of the at least one auxiliary roller row actuator,
• wherein each of the at least one auxiliary roller row actuators is pivotally connected to the frame, and each of the at least one auxiliary roller row actuators is pivotally connected to the row of auxiliary rollers by a corresponding linkage assembly, each corresponding linkage assembly pivotally connected to the row of main rollers, and
• wherein each corresponding linkage assembly comprises a first linkage arm and a second linkage arm, wherein:
• the first linkage arm is pivotally connected to the corresponding auxiliary roller row actuator, the second linkage arm and the row of main rollers;
• and
• the second linkage arm is pivotally connected to the first linkage arm and the row of auxiliary rollers.
