A local guy is selling 36" Exmark Turf Tracer HP 15 Kawasaki. The machine is 4-5 years old, sulky, and of course, floating deck. He says it has about 300-400 Hours approx. He wants $2400 or best. What do you guys think? He says it has no problems. He actually has an identical machine only 5-6 years old, 15 HP Kohler and no sulky and 500-600 Hours. What do you think they are each worth? He says no problems on any of them. I am going to see them tomarrow. Thanks in advance.
