John Deere 570 to 672 — what the number and the letter each tell you
The John Deere motor grader group on SpecCodex spans several decades of production history in one bucket. It started in November 1967 with the JD 570, the Industrial Division's first fully hydraulic, articulated-frame motor grader; the larger 670 and 770 followed soon after. From the start, the model number denoted size class: 570 the smallest line, 670 the mid-size one.

In the late 1970s Deere added the 672 and 772 variants, fitted with an engageable front-wheel drive that automatically kicked in when it sensed slip at the rear tandem — hence the “2” after the first digit. The letter that follows (A, B, C, D…) does not mark a size class; it marks successive technical revisions of the same model line across model years.
Despite the spread, there is a technical common thread: nearly all recorded models run six-cylinder engines, displacement sits between 4,975 and 18,107 cm³, and operating weight between 8,210 and 22,053 kilograms.
For a used purchase, take a close look at the moldboard and circle: wear on the circle gear teeth and slide shoes is normal on graders, and it's worth checking the front-axle leaf springs, the blade tilt and side-shift cylinders, and — on the 672 variants — whether the front-wheel drive still engages.
Since the letter and number together define the exact spec level, the serial number on the plate should always be checked against the manufacturer's records.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
