Abstract
An agricultural machine such as a high clearance sprayer is provided with a hydraulic warm-up system for warming multiple hydraulic circuits. The sprayer includes a parking brake system, a hydraulic system including a parking brake hydraulic circuit and at least one ancillary hydraulic circuit, and a hydraulic warm-up system. The warm-up system includes a warm-up circuit defined by the parking brake hydraulic circuit and the at least one ancillary hydraulic circuit so that oil flows through the parking brake hydraulic circuit into the at least one ancillary hydraulic circuit. As a result of this oil flow, the at least one ancillary hydraulic circuit is warmed to improve functionality of the ancillary hydraulic circuit. Where the parking brake is activated and the sprayer is stationary, oil may be diverted to the ancillary hydraulic circuit.
