I would not buy a Lesco at any price. Lesco machines were built by MTD, and, were basicly Cub Cadet/Commercial machines in Green paint. Parts PROBABLY are available direct from MTD online. I would not count of good parts availability though, since the last Lesco machine rolled off the assembly line quite a few years ago.
Almost any other used commercial ZTR will be better over the long run, depending on what type of maint. it has received.
