After spending more time under an MTD lawnmower-15hp,single cyl,42in cut-than actually using it over the past 7 seasons i am ready for a better mousetrap. The question I have is an obvious one. What should I buy to cut three acres, once or twice a week for the next ten years? Cost is important, but so is time. I want to get the job done in the shortest possible time with the least amount of hassle. There must be a better way than just buying a higher end rider like the one the local JD and Cub Cad dealers want to sell me. Any advice is very much appreciated by one who basically likes doing the yardwork but doesn't want to be totally bogged down with just the grass cutting portion of it every week! Thanks!
