We've got a 06' Lazer Xs 66". We have the updates for the baffles and pulley's. Now,last year we would leave just a little strip of grass when we mowed. But with the update, thats gone but we can't get the grass (that the tires run) over to lift up without using high lift blades. The problem is that the high lifts pull too much little junk out of the grass and this causes us a lot of blowing after cutting to clean this up. Double cutting it doesn't help. When we use mulching blades, they cut good except the can't pull the grass up so we have high and low spots. Any advice?
