I am buying a ZTR to mow 3-4 acres at my home. I am leaning toward a Scag tiger cub with 48" deck. My only concern is there are no anti-scalp rollers on front-center of deck. The landscape is not the smoothest. How important is it to have rollers in center of deck? Is this going to cause a problem? My other option is Exmark Lazer CT, but I really don't trust the dealership. I really like the Scag dealer.
