I am looking at purchasing a Rear Engine Riding Mower-I have 1/2 acre to cut and live at NJ shore area-so its a bid sandy. I want to spend between $1,000-1,500. 1. What is the minimum HP to get? 2. Which offer an option to add snow plow on front? 3. What brand-Murray, Stanley, John Deere, Yard Man, Sear Craftsman? Thanks for your help.
