I was at the deere dealer and noticed over 50 new john deere zero turns, 4 new gators with liquid fert spray tanks and some other new equipment. I asked them what they are for since they where all put to the side . The manager told me a local lawn company is trading in there old mowers for new ones. I could not believe it. Some where 72 inches others had some tweels but not every mower had tweels. None had suspension seats. I guess they choose what they needed and figured tweels not required on every mower in there fleet. I would love to write the check for that purchase.
