The implement pump is a variable displacement pump that supplies oil to the implement control valve. The flow varies to match the load sense demand of the system to maintain margin pressure. The implement pump works to meet the full commanded flow of oil to the hydraulic system. The implement hydraulic system is controlled by the machine ECM, implement ECM, and various operator controls.
