Swisher 60" 3 blade. Parked on level cement the 3 blades seem to measure good. You know, from the cement to the blade tip is the same. I know this heavy turd sinks in the grass, but I try to mow a few feet and see which blade is low or high and shim the blades/bearing holders till it looks better. But it is never consistent. Looks great here and awful there...How do you guys get it right or close to it?
