I had a friend ask me if i was interested in purchasing 2 used exmarks last week. One was a 72" and the other 60", liquid cooled engines; both w/ about 1900 hours on each. They looked like they were in decent shape, but they are getting pretty old. I have a couple right now and had to put in hydro pumps every time a mower would hit 2000 hrs. How much would you be willing to pay for something like this. Do think i would be better off just getting them brand new?
