I am going to buy a new Hustler Super Z 27/60 in about a week. I currently am running a Great Dane Surfer 22/61 that has 470 hours on it after 4 summers of mowing. I have had no major problems with this machine. The GD has new belts and a new set of tires. I have really taken care of this machine. The motor oil has been changed every two weeks and a new oil and air filter every month. The deck has been cleaned each day after use and has been kept inside every night. All other scheduled maintenance has been taken care of. My current dealer say that I have taken great care of my machine and he told me that he would give me at least $3200.00 on a trade for a SCAG ztr. The Hustler dealer will not take a trade in. He told me that he didn't have a market for my machine and he also told me that he couldn't really give me what the machine is worth. How much do think it is worth?
