Ever needed to order parts, check your warranty, or register your lawn mower? You’ll need the serial number. Almost every lawn mower—push, self-propelled, or riding—has a unique serial number and model number, just like a car or appliance. Here’s everything you need to know about mower serial numbers and why they matter.
Quick Answer: Yes, Lawn Mowers Have Serial Numbers
All major lawn mower brands include serial numbers on their products. This applies to gas, electric, and battery-powered models, whether walk-behind or riding mowers.
What Is a Serial Number on a Lawn Mower?
- Unique Identifier: The serial number is a specific code that identifies your individual mower.
- Used For: Ordering parts, checking for recalls, registering for warranty, and confirming the year of manufacture.
- Format: Usually a combination of letters and numbers, distinct from the “model number” which tells you what type of mower you have.
Where to Find the Serial Number on a Lawn Mower
- Push/Walk-Behind Mowers: Look for a sticker, plate, or stamped number on the mower deck (often near the rear wheels, under the handle, or by the engine housing).
- Riding Mowers: Check under the seat, on the frame by the rear wheels, or on the dashboard area.
- Engines: Engines like Briggs & Stratton, Honda, or Kohler usually have their own serial/model number stamped directly on the engine cover or block.
- Electric/Battery Mowers: Look near the battery compartment, handle, or underneath the deck for the serial number label.
Why the Serial Number Matters
- Essential for ordering the right parts or accessories
- Helps with warranty claims and product registration
- Needed for service, recall checks, or insurance claims
- Can reveal the manufacturing date and specifications
Comparison Table: Model Number vs. Serial Number on Lawn Mowers
| Type | What It Identifies | Where to Find | Used For |
|---|---|---|---|

Frequently Asked Questions
What if my serial number is worn off or missing?
If the label is unreadable, check the owner’s manual or purchase receipt. For riding mowers, the serial may be stamped directly into the frame or under layers of dirt/paint—clean thoroughly and look carefully.
Is the serial number the same as the model number?
No. The model number identifies the mower type and style, while the serial number identifies your individual unit.
Why does my engine have a different serial number?
Engines and mower chassis often have separate serial/model numbers—always check both if ordering parts for the engine itself.
Conclusion
Yes, lawn mowers have serial numbers—and you’ll need yours for parts, warranty, and service. Take a photo or write it down for easy access, and you’ll save time and frustration the next time your mower needs attention!
