WARM-UP OIL MANAGEMENT STRATEGY

Abstract: a hydraulic system of a work vehicle includes a recirculation valve which may be closed during a warm-up mode of operation so that conditioning hydraulic fluid from a conditioning hydraulic fluid pump flows through a high pressure relief valve to a conditioning hydraulic fluid reservoir and recirculates from the conditioning hydraulic fluid reservoir back to the conditioning hydraulic fluid pump. subsequent to the warm-up mode of operation, the recirculation valve may be opened so that conditioning hydraulic fluid from the conditioning hydraulic fluid pump flows through a low pressure relief valve to a main hydraulic fluid reservoir.
