I live in eastern Mass and we have a publication that has used goods. Listed under farm and garden I counted about 60 adds for WB mowers all kinds belt and hydro brand names Exmark,ferris,scag,burton J.D and bobcat. Some adds were going out of business. Is the trade-in value low for this type of mower? I was thinking of picking one up for a backup. Is their anyway to find out the value of this equipment?
