Bobcat Serial Number Lookup: Find Year by Serial Number
💡 Quick Answer: Bobcat Serial Number Location
Bobcat serial numbers are 9 digits split into two parts: the first 4 digits identify the model/engine combination, and the last 5 are the production sequence. The model year is printed directly on the identification plate.
Where to find it: R-Series (2020+) → right side rear above tailgate. M-Series (2010+) → right side of main frame. K-Series (2007-2014) → rear frame upright. For exact parts fit, always use the serial number—not just the model year.

The serial itself typically follows a 9-digit (4+5) structure: the first 4 digits identify the module (model/engine combination) and the last 5 digits are the production sequence. For parts accuracy, use your serial number—not just model year.
Whether you're hunting for maintenance records or ordering new parts, knowing your Bobcat's serial number can save you a lot of time and hassle. You can find it in several places, like the machine itself or even in the user manual, and understanding what it actually means can unlock a treasure trove of information about your equipment. Plus, if you ever need to contact your dealer, having that number handy can make everything run smoother.
Where to Find Your Bobcat's Serial Number

If you're knee-deep in dirt working with your Bobcat and suddenly have to deal with mechanical failures or service schedules, you might need to pinpoint your serial number quick-smart. It's like the ID card for your rugged piece of heavy equipment: totally unique and super important for figuring out the exact model, original engine, and correct configuration of your Bobcat.
On the Machine
For most Bobcat heavy hitters, like excavators and larger machines, you want to check around the product identification plate. This is often located near the boom swing or under the left lift arm, although it can vary depending on the model. And, if you're pals with a Bobcat mini-X, peek under the left support arm. Just look for a sturdy plate that's playing home to a string of numbers — that's your machine's serial number plate.

In the User Manual
The user manual is packed with nuggets of info, including your machine's serial number. Flip to the reference section upfront, and voila, there's your number along with other juicy details about your Bobcat. Now, if you were on top of things when you first bagged your Bobcat, the dealer might've filled out this section for you.
Through the Dealer
Maybe you bought second-hand, or your equipment has been around the block, and the serial number on the machine has played a disappearing act. Fret not. Your Bobcat dealer is the detective you need. These folks are like walking encyclopedias for all things Bobcat. They keep a record of serial numbers, which means a quick call or email could sort you out.
Understanding the Serial Number Plate
This nine-digit powerhouse is split into two bits. The first four digits are all about the model number and the engine mash-up, revealing exactly what you're working with. Then, there's the five-digit Production Sequence Number, and this puppy gives you the dirt on where your machine fell in the assembly line dance.

Importance of Knowing Your Bobcat's Serial Number
Understanding your Bobcat's serial number is as crucial as having the keys to operate it. That jumble of digits isn't just there for show—it's basically the fingerprint of your machine, unique and incredibly informative. With each set of serial number breaks, you might discover a whole new set of features or changes in your Bobcat.
Maintenance Records
Peek beneath the rugged exterior of your Bobcat and you'll find that its serial number is the key to its past, present, and future. Need to order a new part? Get an update on the maintenance schedule? Your serial number is your go-to guy.
Parts Ordering
Ordering parts without your Bobcat's serial number is like grocery shopping blindfolded. You might end up with something you didn't want, like a size 10 boot for a size 8 foot. The serial number, with its handy-dandy model and production sequence details, is your passport to a smooth transaction.
Insurance and Registration
Think of the serial number as the VIP pass to Bobcat Club—it's what you need to insure your machine, handle claims efficiently, and show that you're the legit owner. Without it, you're just another person with a cool-looking but unidentified piece of metal.
Why Serial Beats "Model Year" for Parts
Bobcat parts catalogs are serial-driven. Year-only lookups can be misleading due to mid-series changes. Use the serial for precise fit.
Conclusion
Knowing the serial number of your Bobcat is like holding the secret sauce to equipment maintenance, support, and recovery. That tiny string of nine digits uniquely identifies your machine's exact model and production run. This info is a gold mine because it helps you nail down service schedules, avoid mishaps from mechanical failures, and even track down your trusty sidekick if it decides to take an unauthorized field trip.
