hey guys i am looking for a 2nd walker mower for a back up mower. I dont want to buy a new one but i dont want to buy a head ache either. Please give your opinions on this mower. 20 hp kohler walker 525hrs 9.5 bushel hopper 48in deck. the guy is askin $6000.00. Is this a good deal. It looks real nice seems to be taken care of. The best part is it is in my home town. So no travel to get it. Thanks in advance.
