Note: Once the hitch and trusses are installed, the hydraulics
may be hooked up. All models will be shipped with hoses

need to be hooked up to fittings. The hose ends and fit-
tings will be marked with color ties and will need to be
hooked up with matching colors. Be sure to get the hoses
hooked correctly or hydraulics will not work correctly, Re-
fer to hydraulics in parts manual for hydraulic layouts.
