Made in China? Mexico, South America, sure. But I don't think there's much American market Deere equipment that's made in China. JD tractors are head and shoulders above any other tractors, and I say that coming from a production agriculture background, where the smallest tractors we use in the field are over 100hp. Red tractors are barely adequate, and everything else is worse.
But lawnmowers...there are at least two grades of Deere mowers. The ones you can buy at Lowe's, Home Depot, farm stores - those aren't real John Deere. They are contract made and they're no better than Cub Cadet or Lawn Boy or Poulan or whatever else. But the ones you get at a dealership are the real deal.
