Mick, If you can get that turbo baffle (red line in your last pic) go all the way to the 11 o'clock spindle housing bolt, you can then get maybe a longer spindle bolt. The threads would protrude further through the spindle housing and you could then BOLT the turbo baffle on. This is how the turbo baffle on my SCAG 48" Walkbehind is attached. The turbo baffle produces lift on that discharge side. On my old Ultra-Cut Lazer, if I needed extra suction to lift lazy grass, I'd go over it with the discharge side and it would lift it up. Edges along driveways and sidewalks, the grass would grow over the pavement. If I mowed it with the trim side, it wouldn't suck it up off the pavement and cut it. If I ran down the other direction (blowing ONTO the pavement, it would always leave this edge cut better.
