Abstract: A method and apparatus of a work machine wherein an operator traverses the work machine within an operator selected speed range. The operator positions a speed-range control device to select the operator selected speed range, thus, sending a speed-range signal from the speed-range control device to an electronic control module indicative of the position of the speed-range control device. The speed-range signal is converted to a scaling factor to re-calibrate at least one drive map indicative of the scaling factor. The operator then may position a control device to traverse the work machine within the operator selected speed range.

Abstract: A work machine is operably coupled to an interchangeable hydraulically-driven implement via at least one hydraulic line. When changing the hydraulically-driven implement, high pressure trapped within the hydraulic line may cause difficulties in disengaging the attached hydraulically-driven implement from a body of the work machine. The present invention relieves the pressure in the hydraulic line by energizing at least one electronically controlled valve while an engine of the work machine is inactive. The valve is operably coupled to an electrical actuator and is moveable between, at least, a first position and a second position. When the valve is in the first position, the hydraulic line is fluidly connected to a low pressure line. A control system includes a pressure release controller that is operably coupled to energize the electrical actuator and move the valve to the first position when the engine is inactive.
