I sold John Deere equipment for several years, but I have a Toro mower. I don’t know about “Wuhan” engines, but my Toro has a Kawasaki. Perhaps Toro has changed, but Kawasaki has been their basic power plant for years. The 930 John Deere is a nice mower, but is pretty pricy compared to others in its price range. JD uses several different engines in their mowers, namely the Kohler and the Kawasaki. I have owned and run a number of different mowers over the years and in my experience (as well as from input from numerous customers), the Kawasaki engine is damn near bulletproof compared to other offerings out there. I would definitely favor the Kawasaki engine regardless of the mower manufacturer, because the engine is a huge part of the deal. As far as the JD, you might want to check out the 915E as it could save you a few bucks. If your budget isn’t a consideration. The 930 would be the way to go with the JD. Whatever you buy, the dealership (parts, service) is a big consideration as well. In the case of JD, just bear in mind that their service department is going to charge you the same hourly rate for service as they charge the guy whose cotton picker they are working on. The JD dealer I worked for would routinely charge like $150 for an oil change on a zero-turn mower. You can buy a filter and a couple quarts of oil for that mower for $25, max. Just be careful-and remember the term “Kawasaki”. Just an opinion based upon lots of experience.
