We have been running Massey combines for yrs and are in need of an upgrade on one. Due to the lack of dealerships in the area we are looking at a John Deere. I know nothing about a John Deere and was wondering if there is anything I should be looking for when purchasing one. We are looking at a 04 9860 with around 1000 hrs on it. We mainly grow wht, canola, and barley. thanks.
