Abstract
An agricultural tillage implement includes a main frame including a hitch extending in a travel direction, at least one secondary frame, a plurality of rolling basket assemblies and a pressure control system. The secondary frame is coupled with the frame. The plurality of rolling basket assemblies include first and second rolling basket assemblies. Both first and second rolling basket assemblies are coupled to the at least one secondary frame. The first rolling basket assembly has an effective length, and the second rolling basket assembly has a different effective length. The pressure control system is configured to supply different selected pressures to the first and second rolling basket assembly to substantially equalize a down pressure per unit of effective length of the rolling basket assemblies.
