I was talking to a buddy of mine at work today, and He has been checking out the prices on some commercial mowers. I wasn't surprised at the Hustler Super Z price, or the eXmark Lazer Z price because I have been pricing them myself, but the John Deere 777 price threw me for a loop. These prices were for cash without very much negotiating . The Super Z with the 27 hp air cooled Kohler was $7900. The eXmark Lazer Z with the 27 hp air cooled Kohler was $8200. The John Deere 777 had the 27 hp liquid cooled Kawasaki, and it was quoted as being $8200. This was a big surprise to me because when you add the liquid cooled Kawasaki engine to the eXmark or Hustler they are at least $1000 higher than they are with the air cooled kohler. How is John Deere able to sell their ZTR so much cheaper ??. John Deere also has a rebate going so it would actually be less than $8000. I'm going to check this out this weekend because my friend may have not understood the correct engine options . He also said that the dealership had a used 797 72" with less than 30 hours for around $7500. Your opinions ?
