Abstract:
A control system for a work implement of a machine having a frame is provided. The control system includes a pair of lift cylinders operatively coupled to the work implement and configured to raise or lower the work implement with respect to the frame. Each of the lift cylinders has a rod end and a cap end. The control system includes a first cross-over line configured to fluidly communicate the rod ends to each other and a second cross-over line configured to fluidly communicate the cap ends to each other. The control system includes a cross-over valve disposed in one of the first and second cross-over lines and configured to regulate a flow of hydraulic fluid therethrough. The control system further includes a controller communicably coupled to the cross-over valve and configured to at least partially close the cross-over valve during a dump cycle of the work implement.
