Abstract
The present disclosure provides a method of controlling a work implement of a machine. The machine includes a controller for controlling the implement, a sensor, a hydraulic pump for producing a fluid pressure, and a valve disposed in communication with the pump. The method includes selectively operating the machine according to a first operating mode, wherein in the first operating mode the hydraulic pump is operably controlled to produce a fluid pressure between a first pressure and a second pressure, the second pressure being greater than the first pressure. The method also includes sending a signal to the controller, the signal corresponding to a request for a fluid pressure greater than the second pressure. The method further includes transitioning from the first operating mode to a second operating mode and increasing the fluid pressure from the second pressure to a third pressure during the transition.
