I own a John Deere 2010 crawler loader with a Deere "quick connect" 50 backnoe. I have owned it for 30 years. Over that time I have rebuilt the engine and the transmission, and it runs fine, but it is still a vintage machine (made 1960-1964), and parts are becoming hard to find. It utilizes a gear timer, not a belt. Does anyone know where I could buy replacement timing gears? Anything out of a junk yard is likely to be as worn as mine are. I could not find parts online at John Deere. Any help will be much appreciated.
