I have a 36 and mine doesn't have that middle bow between the rear and front. unscrew the windshield and pull the levers down below the wood bow and she should go.
Yeah I can only get to this point what do I do next ??? Levers been pulled the top iron bar is in the way ? Won’t let it do the accordion
it does take a little wiggling as it collapses you move the top material and push slightly down as you go
