I think I have narrowed my homeowner ZTR search to 2 models. I am looking at: A Cub Cadet Z-Force 48" with 22hp Briggs & Stratton Intek and a Toro Timecutter ZX 19-52 (19hp Kawasaki, 52" deck). I only want to spend around $4000 and I want a new machine for the warranty. The Cub Cadet lists right at $4000 and I get sort of an employee discount with the Toro that puts it in the $4000 ball park. So with cost not the issue, each has features that I like and dislike but which has the better engine, Cub or Toro? Any opinions?
