Here is my list:
1. John Deere 4320. Circa 1971. I'll take one with a canopy and beefy tires, please.
2. New Holland TN75S-A. Shuttle-shift and SuperSteer are musts.
3. John Deere 4020 Diesel. I'd prefer a wide-front end, powershift, and 18.4 rubber on the rear.
4. Ford 5000 Diesel. I'd prefer a manual 8 x 2, but I'll even take one with the Select-O-Speed transmission.
5. John Deere 3020 Diesel. I would prefer a wide-front end and powershift, but would consider PsychoRange.
I could go on and on. The list should be at least a Top-20 list, I know. But we'll start simple.
