I am starting up a small lawncare business cutting 10-20 1/4 acre lots this summer. I have been told good things about Bob Cat mowers. Looking to buy a 48" walk behind. The local pricing is about $2,650.00 for a new one with a Kawasaki 15 engine. I did find one other new one (which is last years model for $2,400.00) but it has a Kohler engine. A. Would you reccomend buying a Bob Cat for the jobs I need it for? B. Would you buy the Bob Cat with the Kawasaki engine and pay $250.00 more or buy the Kohler engine? Thanks in advance for all of your help.
