Hi, Just got back from a dealer who carries Ferris and scag ztrs. I'm seriously, considering either the Scag Tiger Cub 48"/19hp Kawasaki ($6200) or th Ferris IS 1500Z 48"/21hp Kawasaki ($5500). Are these hp ok for a 48" deck? I'm mowing my 1.5 acre residence. How do these brands compare to the Dixie Chopper or Exmark brand. To be honest I never heard of Ferris or Scag until visiting this forum. By the way this forum is great!!!
