I received my 2006 Lazer Z CT with approximately 500 hours on it and had to replace the PTO clutch, spindle bearings, belts, blades, voltage regulator, tires and do a carb rebuilt all in the first year that I had it. The mower was used to cut just 3 acres on a residential property and was always stored inside. You have to be very thorough with our inspection of the equipment and look for anything that looks worn, and listen for all of the little noises that the mower makes, at low throttle, high throttle, with the PTO engaged or disengaged and while traveling in all directions. As well built as Exmarks are, and I would never steer someone away from one if they really want it, the replacement parts like clutches, hydraulic pumps and drive motors can be EXPENSIVE. If I were to lose just one drive motor on mine I would be out almost $500 for the parts alone. But with all that being said, if everything functions properly and you do not see what appears to be any urgent repairs, then why not? The cost of a new, comparable model would be 2-4X what you would pay for a used one. That cost savings can fund any upcoming repairs that you may or may not have.
