1. An agricultural tillage implement having a fore-and-aft extending frame and adapted for forward movement over ground, the tillage implement including: fore-and-aft extending support members attached to an aft end of the frame; an earthworking tool depending from the support members; support arms having forward ends pivotally connected to aft ends of the support members; a rolling basket structure connected to aft ends of the support arms and biased downwardly into ground engagement for rotatably engaging the ground behind the frame; an extendible and retractable hydraulic cylinder; a connection attaching the cylinder between the support members and the support arms; wherein the cylinder is operable on-the-go to pivot the support arms and lift the rolling basket structure relative to the frame against the bias out of engagement with the ground to provide rolling basket structure lift independently of vertical movement of the frame; and including a lost motion connection between the cylinder and the support members facilitating pivoting of the support arms and movement of the rolling basket structure upwardly relative to the frame against the bias while the basket structure engages the ground.
