After reading about mowers rolling and injuring operators, I decided to look for a hydro 48 inch walk behind for the hill above a retaining wall behind my house and to make a pass around my pond before using my zero turn. Finally found one and I picked it up yesterday. Owner said it was used commercially for a year and then was only used on their personal property. I'm not sure of the age - any ideas? Bobcat Mower Model # 930306 Deck Model # 934400 Engine Kohler CV15S (SKH426U1G2RB) The mower had been serviced a couple months ago and hardly used. The oil in the engine and hydro appears fresh. The filter pre-cleaner has some grass on it but I mowed my hill before checking it so it may be MY grass. Anyway, it appears to be in pretty good shape. The only issue I have currently is that when it is in neutral and you let go of the handles, it creeps in reverse. Is there a way to fix this or is it expected? I've emailed Bobcat asking for a manual but I'm sure they won't respond until next week at least. Thanks for any help.
