I have a friend that is getting out of the lawn business. He has offered to sell me his Scag 28 hp water cooled Kaw. 60" cut mower in very good condition withh 650 hours on it for $5800. Is this a good deal? He wants to sell it now and I was thinking of buying it and selling it this spring when the market was better and try to make a few hundred bucks. Not sure what model it is but the frame is about the same size as my 27 hp Lazer Z (little longer, wider and lower to the ground than the Lazer). Any advice would be appreciated. Thanks.
