Wazzbat, it sounds as if your fixed blade has been adjusted recently by an expert, so it should be OK. There has to be slight contact between the rotating cylinder blade and the fixed blade to cut grass properly, but the contact should sound smooth: a sort of hiss. If there is heavy scraping or (heaven forbid) clanking, the contact is too heavy. Adjusting the fixed blade to get the right contact is a bit tricky, since it has to be adjusted on both sides of the mower, rather carefully. Because both of your blades have just been rather expensively resharpened, I suggest you study the subject a bit before attempting adjustment. Heavy contact ruins all that sharpening work in a fairly short time.
