This year, weather pending, me and my business partner really want to add a legitimate employee. I've never used a walk-behind mower or even seen one running really. I was wondering, as far as adding an un-experienced employee, would it benefit to add a walk-behind mower to my line-up? Are they easier to learn that a zero turn? Better on the liability side of things? Safer? Easier/harder to screw a lawn up (scalping, running over non-mowable objects, etc)? I figured one of the best attributes is that if we found someone reliable enough, we could send them out in a compact truck with ramps and no trailer to do smaller yards: less overhead and no worrying about their "trailer" skills. Any thoughts?
