3. Loosen hardware (A) at cross-support outer brackets.

4. Remove hardware (B) from cross-support center connections.

NOTE: Tube to frame hardware will need to be loosened for the following step.

5. Spread hitch tube ends (C) into alignment with rear bar brackets (previously installed on seeding tool).

NOTE: Final attachment and tightening of cross-support can be delayed until hitch tubes are attached to rear bar brackets.

6. Extending both sides equally, align holes in cross-support brackets and attach with previously removed hardware (B). Use additional flat washers (D) (provided) to fill gap between "over" bracket and connecting strap. "Under" bracket rests flat on strap and does not need spacer washers. Leave hardware loose until instructed to tighten.

7. Slide cross-support assembly as far forward as possible and tighten hardware (A) at cross-support outer brackets.
