I am thinking about starting a lawn care business this year in the Portland, ME area. I am currently doing as much research as I can before I lay out some cash for a mower. A lot of lawn care people I have seen, or talked to, in this area seem to like Walker mowers. Does anyone have any advice or Pros and Cons to mention about them? A local dealer gave me a rough estimate of $8700 for a 20hp Model T. Does this sound like a reasonable price? Some other mowers I am considering are the 23hp Exmark Lazer HP and a 23hp Toro Z100 series. What are your opinions on an out-front/fulltime bagger versus a mid-mount machine? Are there benefits worth considering if I have to decide between a Kawi or a Kohler engine? Any info is greatly appreciated.
