The tray supporting the discharge hose storage reel has three positions; a driving position, a use position and a maintenance position. The four-bar linkage assemblies include a ground, a crank, a connecting rod and a follower. The tray using the four-bar linkage assemblies and hydraulic cylinders is raised and lowered along an axis vertical to the ground. The tray does not move to and away from the vehicle.
