The serial number on a Grasshopper mower provides critical information about its model year, manufacturing details, and specifications. In this post, we’ll walk you through the process of locating and interpreting the serial number on your Grasshopper mower, ensuring you have the knowledge to maintain and maximize your equipment’s potential.
How to Read a Grasshopper Mower Serial Number
Step 1: Locating the Serial Number
Before you can read the serial number, you need to find it. Grasshopper mowers have their serial numbers stamped on a metal plate or sticker, typically located in one of the following places, depending on the mower type:
- FrontMount Tractors: The serial number is usually found under the seat, on the right side of the tractor frame, near the throttle. Lift the seat to access the metal tag.
- MidMount Tractors: Look under the seat, on the right side of the frame, for the serial number plate.
- Mower Decks: For deck-specific information, check the right, back side of the deck for a separate serial number plate.
- 100V Series: The serial number is located on the tractor frame, between the engine and the left tire.
- Implements: Serial number locations vary by attachment, but they are typically displayed in an easily accessible spot on the implement.
To locate the serial number, sit in the operator’s position and check these areas. The number is usually stamped on a metal plate or a sticker with the model number and other details. For example, a Grasshopper 725DT might have a serial number like “7115851” on the tractor frame, while the deck might have a separate number.

Step 2: Understanding the Serial Number Structure
Grasshopper serial numbers follow a pattern that provides key information, particularly about the model year. While the exact format may vary depending on the mower’s age and model, here’s a general guide to interpreting them:
- Model Year: For many Grasshopper mowers, the first or second digit of the serial number indicates the model year. For example:
- A serial number starting with “57” (e.g., 5712930) typically indicates a 2007 model, as the second digit “7” corresponds to the year.
- For older models (pre-2000), the first two digits often represent the year, such as “91” for 1991 (e.g., 913175).
- A 2024 guide from New Holland Rochester provides a table for older models: 74XXX (1974), 75XXX (1975), up to 99XXX (1999), and 00XXXX (2000) onward.
- Sequential Numbers: The remaining digits are usually sequential, indicating the production order of the mower. These numbers help Grasshopper track individual units but are less critical for owners.
- Model Number: The serial number plate often includes the model number (e.g., 725DT, 223, 618), which identifies the specific mower type and configuration.
For instance, a serial number like “6012930” was confirmed by a Grasshopper representative to indicate a 2010 model, as the first two digits “60” align with the year 2010.

Step 3: Verifying the Model Year
To confirm the model year, you can cross-reference the serial number with Grasshopper’s records or use resources like the New Holland Rochester table. For example:
- 1974–1983: Serial numbers are in the format 74XXX to 83XXXX, directly corresponding to the year.
- 1984–1999: Serial numbers may include a leading digit or follow a similar pattern (e.g., 91XXXX for 1991).
- 2000 and Later: Serial numbers often start with a two-digit code (e.g., 57 for 2007, 60 for 2010).
Step 4: Using the Serial Number for Maintenance and Parts
Once you’ve decoded the serial number, you can use it to:
- Order Parts: Visit Grasshopper’s official website or a dealer like The Mower Shop, Inc., to access parts diagrams.
- Download Manuals: Grasshopper offers operator’s manuals for tractors and decks, which can be ordered online or through dealers. The serial number ensures you get the correct manual for your mower.
- Troubleshooting: When seeking technical support, provide the serial number to dealers or experts to get precise advice on issues like deck leveling or transmission problems.
