Hello I am currently looking to mabey replace my John Deere 737 with a 54 inch deck. I have a 2 bag bagger on it. I have a realitive that wants to by the machine. I am looking at replacing it with mabey a X740-X748 with a 62 inch deck with a dump from seat bagger, OR a Z840A with a dump from seat bagger. The only thing holding me back from the new Z is I want a Diesel, and you cant get a diesel unless its the monster 997. And I dont want it Have any of you heard weather john deere is going to offer a smaller diesel Ztrak next year? What do you guys think?
