A guy I know is selling an 48" belt scag, minus the engine. I'd be interested, but I'm not sure what to check out on the mower, or where to start on price. I'm not sure how old the mower is, I'll be sure to ask him, but for now let's assume its 5 years. A 15 hp engine might cost $500-$600, so based on the above information, what might be a good offer for the mower? Maybe $350? I just need some input before I jump into something I might regret. Also any general tips for checking out wear on the spindles, etc? Sorry if this is a dumb question, but basically I just don't where to start. Thanks!
