I have put a deposit down on a used DC xwk2501. Can anybody please tell me about this mower. It has a Kawasaki motor. Year, HP, problems, what to look for? I am only paying $2000 for it. It seems a little rough here and there. The hour meter is not funtional. The guy says it uses a little oil and he has it set a 3/4 throttle permanently so it will not over heat. Any info would be helpful. Thank you.
