I need a walk behind deck bigger than a 21". A private seller local to me indicates the following on an Exmark Metro walk behind. It is a 32" deck with a 13hp Kawasaki engine. He has receipt that he paid $2400 NEW. It only has 30 hours on it. PERFECT CONDITION. Selling for $1000. There is no bagger and no mulch kit. DOES THIS SOUND RIGHT? Or is it too good to be true? Is this a good machine? Can it be serviced at home if user only knows mower maintenance a little bit? Any idea the cost of the mulch kit and the bagger that go with this machine? Thanks for help.
