Abstract

An agricultural tillage implement including a frame section having a pull hitch extending in a travel direction, at least one secondary frame coupled with the frame, a plurality of rolling basket assemblies, a geographical position determining device, and a pressure control system. The secondary frame is coupled to the frame. The plurality of rolling basket assemblies are coupled to the secondary frame. The geographical position determining device generates a geo-position signal. The pressure control system is coupled to the plurality of rolling basket assemblies. The pressure control system is configured to supply a selected pressure to each of the plurality of rolling basket assemblies dependent upon the geo-position signal.

First claim

What is claimed is:

1. An agricultural tillage implement for use in a field, the agricultural tillage implement comprising:
a frame section including a pull hitch extending in a travel direction;
at least one secondary frame coupled with the frame;
a plurality of rolling basket assemblies coupled to the at least one secondary frame, each of the rolling basket assemblies having at least one rolling basket coupled thereto, wherein the plurality of rolling basket assemblies includes a first rolling basket assembly having a first length and a second rolling basket assembly arranged outwardly of the first rolling basket assembly and having a second length that is less than the first length;
a plurality of actuators arranged with respect to the secondary frame and the rolling basket assemblies for respectively moving the basket assemblies relative to the secondary frame, wherein the actuators selectively move the basket assemblies in one of a generally downward direction and a generally upward direction; and
a pressure control system coupled to the plurality of rolling basket assemblies, the pressure control system controlling the actuators to:
apply pressures in the actuators in a first direction and alter the pressures applied to the rolling basket assemblies when moving the basket assemblies in the generally downward direction so that a substantially equal down pressure per linear unit of measure of each rolling basket assembly is established when moving the basket assemblies in the generally downward direction; and
apply pressures in the actuators in a second, opposite, direction to lift the rolling basket assemblies when moving the basket assemblies in the generally upward direction.

2. The agricultural tillage implement of claim 1 , wherein each of the rolling basket assemblies further includes:
a sub-frame;
at least one rolling basket rotationally coupled to said sub-frame;
at least one pivoting arm pivotally coupled to the secondary frame, the at least one pivoting arm being connected to the sub-frame; and
wherein respective ones of the actuators are arranged to move the at least one pivoting arm, and wherein the actuators are configured for receiving a pressurized fluid under control of the pressure control system.

3. The agricultural tillage implement of claim 1 , wherein said pressure control system is further configured to alter said selected pressure dependent upon information about a soil characteristic proximate to said rolling basket assembly.

4. The agricultural tillage implement of claim 3 , wherein said information is geo-positionally related.

5. The agricultural tillage implement of claim 4 , wherein said soil characteristic includes at least one of soil content and soil moisture content.

6. The agricultural tillage implement of claim 5 , wherein said soil content includes at least one of soil texture, mineral composition, particle size, organic material, residual material and permeability.

7. A rolling basket implement attached to an agricultural tillage implement having a frame connected to at least one secondary frame, the rolling basket implement comprising:
a plurality of rolling basket assemblies coupled to the at least one secondary frame, wherein the plurality of rolling basket assemblies includes a first rolling basket assembly having a first length and a second rolling basket assembly arranged outwardly of the first rolling basket assembly and having a second length that is less than the first length;
a plurality of actuators arranged with respect to the at least one secondary frame and the rolling basket assemblies for selectively pushing the basket assemblies toward an agricultural field and lifting the basket assemblies away from the agricultural field; and
a pressure control system controlling the actuators to alter the pressure applied to the rolling basket assemblies so that a substantially equal down pressure per linear unit of measure of each rolling basket assembly is established while pushing the basket assemblies toward the agricultural field.

8. The rolling basket implement of claim 7 , wherein each of the rolling basket assemblies further includes:
a sub-frame;
at least one rolling basket rotationally coupled to said sub-frame;
at least one pivoting arm pivotally coupled to the secondary frame, the at least one pivoting arm being connected to the sub-frame; and
wherein respective ones of the actuators are arranged to move the at least one pivoting arm, and wherein the actuators are configured for receiving a pressurized fluid under control of the pressure control system.

9. The rolling basket implement of claim 7 , wherein said pressure control system is further configured to alter said selected pressure dependent upon information about a soil characteristic proximate to said rolling basket assembly.

10. The rolling basket implement of claim 9 , wherein said information is geo-positionally related.

11. The rolling basket implement of claim 10 , wherein said soil characteristic includes at least one of soil content and soil moisture content.

12. The rolling basket implement of claim 11 , wherein said soil content includes at least one of soil texture, mineral composition, particle size, organic material, residual material and permeability.
