I've got a local Exmark dealer that became a dealer after I purchased my Z in 2002. They have been good to me over the last several years as I've used them for a few service needs. Today the salesman made me an offer to trade for a new mower. I'm looking for some feedback on his offer. Current Machine: 2002 Lazer Z 52" 20HP Kohler with 250 hours with the Heavy Duty air filter. On a scale of 1 to 10 it's an 8. New Machine: 2005 Lazer Z 60" 23hp Kohler with 0 hours. Trade difference $2500 Said he was allowing me 5199 for my machine. I simply want more deck and to keep a relatively new machine around to run. The 72" model would require a larger trailer so that will no be happening.
