Hmm they are meant to mow grass they are not a yard vacuum.
You shouldnt need to loosen the blades.
What disc does it have on it, the round stepped one???
You could put two of the later high lift blades on it but in the event of hitting something they will not swing back into the disc, they will hit it.
You could get a later 4 blade disc and put that on. Will cost you more than the mower is worth. And they do not have the recess for the blades to swing back fully either.
There is a photo i uploaded on here somehwere of all the different victa discs.
