Unlocking the mystery of your John Deere 855's age is simpler than you might think. Knowing the year of manufacture is crucial for ordering the correct parts, understanding its potential value, and ensuring you're performing the right maintenance procedures. Thankfully, the serial number holds the key to this information.
Instead of relying on guesswork or vague memories, this guide will walk you through exactly how to find your John Deere 855's serial number and use it to determine the year it was built. We'll cover common locations for the serial number, the decoding process, and even touch on some historical context about this popular compact utility tractor.
Finding That All-Important Serial Number
The first step in determining the year of your John Deere 855 is locating its serial number. John Deere typically places serial numbers in a few common locations, making the search relatively straightforward. Here's where to look:
- On the frame, near the front axle: This is a very common location. Look for a stamped plate or sticker attached to the tractor's frame, usually on the right-hand side (as you're sitting on the tractor) near the front axle.
- On the engine block: Sometimes, the serial number is stamped directly onto the engine block. This can be a bit trickier to find, as it might be partially obscured by hoses or other components. Look for a flat, machined surface on the block.
- Under the seat: In some cases, a serial number plate might be located under the seat. You'll need to lift or remove the seat to check this location.
- On the transmission housing: Less commonly, the serial number might be stamped or placed on a plate attached to the transmission housing.
Pro Tip: Before you start searching, give the areas a good cleaning. Years of dirt and grime can easily obscure the serial number plate or stamping. Use a wire brush and some degreaser to remove any buildup and make the number easier to read. If the plate is painted over, carefully use a razor blade to remove the paint from just the number itself.
Decoding the Mystery: Serial Number to Year
Once you've located the serial number, you need to decipher it. John Deere uses a specific format for their serial numbers, which allows you to determine the year of manufacture. While specific formats can change, the principle remains the same: a specific range of serial numbers corresponds to a specific year.
Unfortunately, John Deere doesn't publicly release a comprehensive, official list for every model and year. However, through research and cross-referencing, we can build a reliable guide.
Here's a general guide to determining the year of your John Deere 855 based on its serial number. Please note that this information is based on available data and may not be 100% accurate for all models. Always double-check with a John Deere dealer or reputable source for definitive confirmation.
Serial numbers typically start with a series of characters that identify the model and manufacturing location, followed by a sequential number. The sequential number is the key to determining the year.
To determine the year, compare your tractor's serial number with the following approximate ranges:
- 1987: 010001 - 020000
- 1988: 020001 - 030000
- 1989: 030001 - 040000
- 1990: 040001 - 050000
- 1991: 050001 - 053000
Important Considerations:
- Model Variations: The John Deere 855 had some variations during its production run. While the core serial number decoding remains the same, minor differences might exist.
- Manufacturing Location: The location where the tractor was manufactured can sometimes influence the serial number format. The 855 was primarily manufactured in Japan by Yanmar, so this isn't usually a major factor.
- Always Verify: As mentioned before, this guide is based on available information. Always double-check with a John Deere dealer or a reputable online forum dedicated to John Deere tractors to confirm the year of your specific 855.
Why Knowing the Year Matters
Knowing the year of your John Deere 855 is more than just a matter of curiosity. It has several practical implications:
- Parts Ordering: Different years of the 855 might have slight variations in parts. Knowing the year ensures you order the correct parts for repairs and maintenance. Ordering the wrong parts can lead to wasted time, frustration, and even damage to your tractor.
- Maintenance Schedules: Maintenance schedules can vary based on the year of manufacture. Older models might require different types of fluids or have different service intervals than newer models.
- Resale Value: The year of manufacture is a significant factor in determining the resale value of your John Deere 855. Older models will generally be worth less than newer models, assuming they are in similar condition.
- Technical Specifications: Some technical specifications, such as engine horsepower or hydraulic flow rate, might have changed slightly over the production run. Knowing the year allows you to access the correct technical information for your specific tractor.
- Identifying Upgrades and Modifications: Knowing the original year of manufacture can help you identify any upgrades or modifications that have been made to the tractor over time. This can be useful for understanding its current capabilities and limitations.
