Attach lift arms to drawbar using 3/4” X 10” cap screws. Position lift arms with following dimensions:
Distance from drawbar center to centerline of first lift arm on either side is 15”.
Distance from centerline of lift arms over sections is 30”.
Distance between centerline of lift arms between sections is 30”.
Use two long lift arms for first section to left of center. Lift arms for adjoining sections must be alter-
nating lengths (short and long).
Assemble sections as shown in parts breakdown on page 4-9. Attach sections to lift arms with chains
and hardware provided. The 9-link lift chain must be attached to the back hole in both lift arm and
