I am looking into getting either a walk behind or a rider mower. Now I have using a JD 332 with a 50in deck for 15 years. Now I am looking at getting either a 61" scag walk behind or a 52" scag tiger cub w/honda engine. Now I have about 4-5 acres of lawn and it takes us now with the JD about 4-5 hrs to mow. It is pretty much flat open lawn, but we do have a hill by our garage, but i figured if I need to I can mow that with the trimmer. I just wondered what mower you guys think would be a better buy. My buddy told me that a walk behind with a 2-wheel sulky is not that bad to ride on, but he said a rider would be alot nicer. Also is there going to be a big difference with mowing times between the 52" and the 61" decks. Just looking to get the best machine for my needs.
