Hi 4567,

I'm not sure we are both on the same page. You can not adjust the bed knife at all, only the height of the reel can be raised or lowered towards the bed knife. If you are attempting to loosen the reel adjusting screw then you must first loosen the bearing carrier nut on the outside of the mowers side plate and then loosen the lock nut on the set screw, only then will the reel move up or down.

Hope this is making sense to you.

Cheers,
BB
