One thing to watch for with small lawn and garden tractors is that engine manufacturers Kohler and Briggs and Stratton have a commercial line (Command for Kohler, Vanguard for Briggs) rated to last in the 2000 hour range, and a cheap line (Courage for Kohler, Intek for Briggs) that are 750 hour rated engines. The better mowers will have the better engines, and of course cost more. The commercial lines of both manufacturers both get high consumer reports and are great long lasting runners. I'd pay the extra for them over the cheaper engine lines.
World War 2 ended almost 60 years ago, and Honda and Kawasaki make great small engines too, if that's what one chooses to use- it can be a personal preference thing of course, but those who have an understanding of a global market are not concerned about a long ended war, and also know that Honda and Kawasaki employ a lot of people in their USA assembly plants. Contrary to popular belief they are not much more expensive than high end Briggs or Kohler (check
www.smallenginewarehouse.com), and the bigger HP engines are all commercial grade with 2000+ hour rated lifespans, they do not make a cheaper lineup of engines. Where I most often buy American brand names when I can, such as my pickup and car, I chose a Honda GX engine as the repower for my Cub Cadet 682. Why? Because in doing a thorough research with everything available, it hands down was the winner in about every category for a new 18 HP small engine and thus far I am ecstatic about its performance in my application.
Most any of the name brand small engines out there now are fantastic. They start easy, run smoothly, and the OHV designs really pinch fuel. All you can do is listen to word of mouth, read consumer reports, and use your best judgement to decide what make to choose.
