When John Deere Stops Making a Part
John Deere supports parts for a long time, but eventually some part numbers are discontinued and marked no longer available, with no replacement listed. A dealer parts store can only sell what John Deere still supplies, so for an obsolete part the answer is often no.
It is common on older lawn tractors such as the LT166, which went out of production in the early 2000s, and on classic farm tractors like the 4020.
Three Ways We Replace an Obsolete Part
- Used original parts from salvaged tractors, inspected before they ship. See used John Deere parts.
- Rebuilt parts for assemblies such as injection pumps, starters, generators and hydraulic pumps.
- Aftermarket and reproduction parts made to the original specification. See aftermarket John Deere parts.
Superseded vs Discontinued Part Numbers
Not every part that looks discontinued really is. John Deere often supersedes an old part number with a new one that still fits. We check the supersession history first, so if a current part will work you get it new, and if not we move to used, rebuilt or aftermarket.
What to Have Ready When You Call
- Model and serial number. See how to find your John Deere serial number.
- The old part number, if you can read it on the part or in the manual
- A photo of the part and where it sits on the tractor

Common Questions

A superseded part number has been replaced by a newer part number that still fits. We check supersessions first, because the newer part is usually the best option when it exists.
We source parts for classic models including the 4020, 3020 and two-cylinder tractors. Give us the model and serial number and we will search.
We will tell you straight away, and where possible suggest a used assembly or a compatible part from a related model.
