Abstract

An agricultural tillage implement includes a frame member, a secondary frame member and at least one double rolling basket assembly coupled to the secondary frame member. A plurality of linkage assemblies interconnect the frame member and the secondary frame member. Each linkage assembly includes an upper link connected to upper connections of the frame member and the secondary frame member and a lower link connected to lower connections of the frame member and the secondary frame member. A force applicator operates against one of the links to move the baskets up and down.

Claims

1. An agricultural tillage implement, comprising:

a frame member;

a secondary frame member including an upper secondary pivotal connection and a lower secondary pivotal connection;

a bracket connected to a portion of the frame member, the bracket extending away from the frame member, the bracket including an upper pivotal connection and a lower pivotal connection;

a first arm extending between the bracket and the secondary frame member, the first arm pivotally connected at one end to the lower pivotal connection of the bracket and at an opposite end to the lower secondary pivotal connection of the secondary frame member, the first arm including an upper pivotal connection;

a second arm extending between the bracket and the secondary frame member, the second arm pivotally connected at one end to the upper pivotal connection of the bracket and at an opposite end to the upper secondary pivotal connection of the secondary frame member;

a force applicator positioned at least partially above the bracket, one end of the force applicator pivotally connected to the first arm at the upper pivotal connection thereof so that the first arm provides a lever;

a side hanger coupled to the secondary frame member, the side hanger including first and second legs extending downwardly and outwardly relative to the secondary frame member;

a first rolling basket connected to the first leg;

a second rolling basket connected to the second leg; and

wherein a portion of the second arm is positioned above the first arm.

2. The agricultural tillage implement of claim 1, wherein the force applicator is a hydraulic actuator.

3. The agricultural tillage implement of claim 1, wherein the lever projects upwardly from the first arm.

4. The agricultural tillage implement of claim 1, wherein the second arm forms an arch near the pivotal connection of the bracket and the second arm, and the arch extends above (a) the pivotal connection of the first arm and the bracket, (b) the pivotal connection of the bracket and the second arm, and (c) the pivotal connection of the force actuator and the first arm.

5. The agricultural tillage implement of claim 1, wherein the bracket and the force actuator are parallel relative to each other.

6. The agricultural tillage implement of claim 1, wherein the pivotal connection of the second arm and the bracket is lower than the upper pivotal connection of the force actuator and the first arm.

7. A double rolling basket attachment for an agricultural tillage implement having a frame member, the double rolling basket attachment comprising:

a forward basket;

a rearward basket directly behind the forward basket;

a hanger having a forward leg forming a rotational coupling with the forward basket and a rearward leg forming a rotational coupling with the rearward basket;

a secondary frame member coupled with the hanger; and

a first arm extending between a bracket connected to the frame member and the secondary frame member, the first arm pivotally connected at one end to a lower pivotal connection of the bracket and at an opposite end to a lower secondary pivotal connection of the secondary frame member, the first arm including an upper pivotal connection;

a second arm extending between the bracket and the secondary frame member, the second arm pivotally connected at one end to an upper pivotal connection of the bracket and at an opposite end to an upper secondary pivotal connection of the secondary frame member;

a force applicator positioned at least partially above the bracket, one end of the force applicator pivotally connected to the first arm at the upper pivotal connection thereof so that the first arm provides a lever; and

wherein a portion of the second arm is positioned above the first arm.

8. The double rolling basket attachment of claim 7, wherein the force applicator is a hydraulic actuator.

9. The double rolling basket attachment of claim 7, wherein the bracket is connected to and projects above the secondary frame member.

10. The double rolling basket attachment of claim 7, wherein the second arm forms an arch near the pivotal connection of the bracket and the second arm, and the arch extends above (a) the pivotal connection of the first arm and the bracket, (b) the pivotal connection of the bracket and the second arm, and (c) the pivotal connection of the force actuator and the first arm.

11. The double rolling basket attachment of claim 7, wherein the bracket and the force actuator are parallel relative to each other.

12. The double rolling basket attachment of claim 7, wherein the pivotal connection of the second arm and the bracket is lower than the upper pivotal connection of the force actuator and the first arm.
