some guy is selling a troy bilt 33" mulching deck commercail walk behind mower for 350. its 8 years old and has 300 hours on it. this guy told me he only used it to mow his one acre yard. he is selling it only because he moved to a sub division in the city and the mower is too big for his yard. is troy bilt a dependable mower? is this a good deal? any experiences with troy bilt mowers?
