Older John Deere Serial Number Lookup: A Guide to Identifying Your Equipment

When it comes to determining the year and market value of your farm equipment, knowing its serial number can be a valuable resource. For that reason, we have compiled this guide to help you identify the serial numbers for older John Deere models.

According to a farm equipment quick reference guide, the source of this information is intended to assist dealers in determining the year and current market value of trade-in equipment. The guide suggests that Deere may have implemented a 'running change' strategy, where they would exhaust their factory parts stock by producing equipment with different serial numbers.

One notable example of this strategy is seen in 1984, when the serial numbers jump to 700010. This is because John Deere produced over 200,000 units of the JD450D tractor in 1982, making it difficult to believe that there was no overlap between production runs.

The guide also notes an overlap between the JD450C and JD450D models, with the power output increasing by just 3 horsepower. Additionally, the JD450B units changed from dry-type steering clutches to wet steering clutches when their stock of parts was depleted, resulting in some late-model JD450Bs featuring the new clutch system.

The main difference between the JD450B and JD450C models is the engine, with the C model featuring a 4/219 CID Turbocharged engine compared to the normally aspirated engine in the B model. Unfortunately, we do not know the exact serial number of the last JD450B produced due to this overlap.

There are also overlapping production runs for the JD450B and JD450C models from 1975 to 1976, where both models were manufactured concurrently. To help you identify your equipment, here are the serial numbers by year for John Deere models JD450 through JD450G:

By knowing your tractor's serial number, you can determine its age and current market value with greater accuracy. Whether you're a farmer looking to trade in an old piece of equipment or simply curious about the history of your machine, this guide is designed to be a helpful resource for anyone searching for information on older John Deere tractors.
