I'm looking at purchasing an older Dixon ZTR Commercial mower and am wondering if others have had good experiences with this equipment. This mower has a 60" mowing deck, Kohler 624CC engine, and costs $2500. For a new 60" Commercial ZTR I would be paying big bucks, which I'm trying to avoid. I'm also a bit concerned with the lower-end Residential ZTRs that are found at the big-box stores, as I've seen some poor reviews. Please let me know what you think. Thanks for your input.
