Knowing the serial number and model number of your Grasshopper is essential for mower registration, parts sourcing and other aspects. Usually, the serial number plate is located under the seat on the frame or on the mower deck. Once you find the serial number, the first 2 or 3 digits can tell you the year of manufacture. For example, if the serial number starts with “74”, it might be a 1974 model. But are there any odd numbers? Let’s dive into this guide now and explore the year of your mower with the Grasshopper serial number together.

Why Do You Need to Know Grasshopper Serial & Model Number?
Accessing the serial number and model number of your Grasshopper mower is essential for the following reasons:
- Mower Registration: If you are able to register your mower, you’ll probably be asked to provide the serial number. Registering your mower is a crucial step for things like getting product information, such as emails about new features, customer service help, and notifications for safety recalls. Besides, you may also need to have your registration sorted out to set up your warranty.
- Sourcing Correct Parts: Knowing the model number and serial number is essential for search right replacement parts. Without these numbers, figuring out if a given part will work for your mower could be a struggle. So, we highly recommend having these numbers on hand.
Common Locations for Grasshopper Serial Number
In order to decode the year of manufacture for your Grasshopper machines, you should find the serial number plate on the machines first. Here are common locations of the Grasshopper serial number plate:
- Behind the seat on the right-hand side of the mower near the console
- Under the seat, on the right side of the frame
- Under the seat for the information plate
- On the back right-hand side of the deck

What Year Is My Grasshopper?
Decoding the year of your Grasshopper mower is super easy with the serial number on hand. Generally, the first two or three digits of the serial number indicate the year of your Grasshopper tractor directly.
For example, if your Grasshopper serial number starts with “74”, it is a mower produced in 1974.
However, Grasshopper changed its serial coding system for models produced in 1987. From this year, it started its serial numbers at 27xxxx to represent 1987, “28xxxx” to represent 1988 and so on. Beware that in 1990, Grasshopper changed its coding system, that is, using the first three digits to represent the year. If the serial number begins with “611”, it’s 2011. “612” for 2012, “613” for 2013 and so on. All in sequential order.
