So Im looking at a Craftsman 18.5HP with a Briggs and Stratton INTEK engine and a Troy Built with a Kohler Command 16HP engine. Im leaning towards the Kohler because Ive heard its a better engine. I also know the Kohler has a pressurized lubrication system and oil filter. Im not so sure about the Intek, but its 2.5HP more (lol)!!!!
