Need some advice on a new walk behind mower. I currently only own a John Deere lawn tractor, 38 inch, non-commercial. I use it for my lawn and a few others. For 2004 I have lined up some commercial accounts and I am expanding to a solid lawn business. I am purchasing a ZTR, but for a 2nd mower, should I keep the John Deere lawn tractor for those small yards or get a commercial walk behind? For your smaller mowers (non ZTR's) what kind of walk behinds do you use and what size. Is there anything wrong with using a John Deere lawn tractor for the smaller lawns? Thanks, really appreciate your feedback.
