I have a BX 2660 with a 60'' MMM, self-balancing/suspended, my question concerns the proper adjustment for the anti-scalp wheels, my MMM was set at 3'', my anti-scalp wheels were set in the proper holes according to the manual, but when I lowered the deck all of the wheels were in contact with the ground, I have raised the wheels quite a bit higher, now when parked on level concrete and the deck lowered the wheels are about 1/2'' from the concrete, it has always mowed very well even with the wheels on the ground, shouldn't the deck be floating/suspended and the wheels making ground contact when mowing over uneven ground??
