John Deere Dubuque Model Designation

What does the letter following my model number mean? John Deere 40, 420 and 430 model tractors had many different variations. Each variation has a letter which is on the serial number tag after the model number. These are the letters for each model:

• Crawler designation is “C”
• Hi-Crop designation is “H”

For example, if your serial number tag has “420 –   W,” then your tractor is a 420 Row-Crop Utility.
