I keep seeing people selling metro walk behinds that are close to brand new, with hardly any use on them. Do these mowers suck or something? Or are guys buying them and finding out it doesn't perform the way they need? Anyone know why people buy these mowers just to sell them shortly after? Maybe its just a coincidence, idk, but I've seen 3 so far in the last week on craigslist here that say "bought brand new in april" or "only 40 hours on mower!"
