Adjustable rolling basket assembly

1. An implement comprising:

a first frame member;

a second frame member movable with respect to the first frame member;

a rolling basket rotatably coupled to the second frame member, wherein the rolling basket is rotatable about a first axis of rotation; and

a biasing member configured to move the first axis of rotation toward a rest position, wherein the rest position is adjustable relative to the first frame portion, wherein the biasing member generates a preload force, and wherein the preload force is adjustable independent of the location of the rest position.

2. The implement of claim 1 , wherein the second frame member is pivotable relative to the first frame member via a second axis of rotation.

3. The implement of claim 2 , wherein the first axis of rotation is parallel to the second axis of rotation.

4. The implement of claim 1 , further comprising an adjustment rod extending between and coupled to both the first frame member and the second frame member.

5. The implement of claim 4 , wherein the biasing member extends between and is coupled to the adjustment rod and one of the first frame member and the second frame member.

6. The implement of claim 4 , wherein the first frame member includes a first mounting point and wherein the second frame member includes a second mounting point, wherein the adjustment rod is operatively coupled to the first mounting point and the second mounting point, and wherein the adjustment rod is configured to vary the distance between the first mounting point and the second mounting point.

7. The implement of claim 1 , wherein the implement is a tiller.

8. The farm implement of claim 1 , further comprising a hitch coupled to the first frame.

9. An implement for use on a support surface, the implement comprising:

a first frame member;

a second frame member movable with respect to the first frame member;

a rolling basket coupled to the second frame member and configured for rotation about a first axis of rotation, wherein the rolling basket is adjustable between a first position, in which the rolling basket is engaged with the support surface, and a second position, in which the rolling basket is disengaged from the support surface; and

a biasing member, wherein the biasing member biases the rolling basket into engagement with the support surface when the rolling basket is in the first position, and wherein the magnitude of the force applied by the biasing member is adjustable while the rolling basket is in the first position.

10. The implement of claim 9 , wherein the second frame member is pivotable relative to the first frame member.

11. The implement of claim 9 , wherein the rolling basket is adjustable between the first position and the second position by moving the second frame member relative to the first frame member.

12. The farm implement of claim 9 , further comprising one or more wheels rotatably coupled to the first frame member.

13. An implement for use on a support surface, the implement comprising:

a first frame member;

a second frame member movable with respect to the first frame member;

a rolling basket coupled to the second frame member for rotation about a first axis of rotation; and

a biasing member configured to bias the rolling basket into engagement with the support surface, and wherein the magnitude of the force applied by the biasing member is adjustable independent of the relative position of the second frame member relative to the first frame member.

14. The implement of claim 13 , wherein the biasing member is configured to move the first axis of rotation toward a rest position, and wherein the location of the rest position is adjustable relative to the first frame member.

15. The implement of claim 14 , wherein the location of the rest position is adjustable independent of the magnitude of the force applied by the biasing member.
