I found this mower for sale from a guy using it to mow his yard in the city. He wants to sell it to me for $400 and it runs and cuts good. I am not real knowledgeable about walk behind mowers yet but want to add one to my equipment without taking out a loan. It is an exmark metro with a 48" deck. Does anybody know what year this may be? All the new Exmarks are red but he painted it years ago. Do you think it is worth $400? Has anyone ever owned or used one of these? Thanks for any help.
