I just got a Bunton 61" Walk Behind that is belt driven. It has a B&S 16HP V-Twin on it. It had been sitting for 3 years and was not running. I now have it running well and have some operator questions. It cuts fine and after some adjustments I have it steering OK and the transmission seems to be working. I can't seem to find a neutral position or reverse. Does this thing have a neutral or reverse? If so, how does it work? How fast should this run in its fastest gear? I have no problem walking as fast as it is moving. I have never had a commercial mower, but I just bought a house with over 2 acres and I thought this would make my life a little easier. I only have $100.00 invested so far and it does work. Any help would be greatly appreciated. I am looking at the possibility of going into the business also and thought this might be a great starter mower.
