Hi Darryl,
If you scroll back in this thread you'll see the picture I posted up of a machine sitting on a lawn with an outboard mounted crank handle. If you look at the catcher on that you'll see that the bar that is mounted from one side of the catcher to the other is around the central point (balance point) of the catcher. When I got mine the bar was mounted approximately half way between the pictured one and the very front of the catcher. There were no signs of the bar ever being fitted in the central set of holes as absolutely no witness marks are visible.
Hopefully that makes more sense in the meantime.
BTW I have now moved the bar to the balance point as that seems better. I'll post a shot later once the sun comes up.
Cheers,
BB.
