I'm going to look at a Scag 36" wb belt drive today. It's 2 yrs old, & has 80 hrs. on it. The guy is asking $2000 but said he would take $1800. Is this a good deal? Is there any common problems with these mowers. I'm just getting started, but 80 hrs doesn't sound like too much to me. It has a sulky with it also. Thanks for your input.
