This is a commercial 36" Exmark Viking Walk Behind mower. 12.5HP Kohler Command Pro Series Motor and 5 Speed Transmission with Reverse. This is a STRONG machine. Terry Eckert at Exmark said " The drive system is unique to this unit and is generally considered to be superior to that of any gear drive mower on the market today". I just put a new Starter recoil and tires (old tires in picture). Email me an offer or interesting trades, 4wheeler, motorcycle, let me know what you have.
