I'm thinking about getting a new mower again. I mow my lawn(.30 acre) and will probably keep mowing my dads (.5-.75 acre). The lawns are flat except my backyard has a small slope towards my fence. I bought a 40" Craftsman plug aerator this spring, I haven't used it yet. I may eventually buy a cart for hauling things around the yard. (Mulch, seed, fertilizer, etc.). I'm thinking probably a 42" or 48" deck. Which sounds like the mower for me and my needs?
