Abstract

A control system for a work implement of a machine having a frame is provided. The control system includes a fluid source configured to provide a supply of pressurized fluid and a pair of tilt cylinders in fluid communication with the fluid source. The tilt cylinders are configured to operatively tilt the work implement with respect to the frame of the machine. Each of the tilt cylinders has a rod end and a cap end between which a regenerative valve is disposed to selectively allow fluid communication between the rod end and the cap end of a corresponding tilt cylinder. The control system further includes a controller communicably coupled to each of the regenerative valves. The controller is configured to vary an amount of restriction in each regenerative valve to regulate an amount of fluid flowing between the rod end and the cap end of the corresponding tilt cylinder.
