I have an opportunity to buy a extra mower thats needs some work. It has 3000 hours but got a new motor around 200. Its a kohler command 27 hp. The mower is a exmark lazer-z with the triple bag system.....the bagging system is a little bent so some grass leaks out. The hydros are a bit spoongy and its gonna need spindles. Oil was changed regularly, but kack of general pm overall. I have the inside track on this and can pretty much name a price......what do you guys think is fair?
