I have a lawn with a pretty steep hill on it that my tractor was just not cut out for, so I'm looking for a good used walk behind. I found a belt driven 2003 Toro Proline 44 with a 15hp Kohler engine. Supposedly it has only 200 hours on it, which is hard to believe for the age, but it's very clean and runs just fine, so it just might be true. The asking price is $850...what would be a good price to offer for this? I know hydros are the way to go, but this is really just for one lawn. What do you think? Go for it or hold out for something else?
