John Deere Lawn Tractor Model Numbers Explained for Homeowners

John Deere lawn tractors have a wide range of model numbers, but understanding what these numbers mean can be a challenge for homeowners.

The model number is typically a combination of letters and numbers, but it doesn't necessarily indicate the tractor's horsepower or engine size. For example, the D110 model has a 22 HP engine, while the D120 model also has a 22 HP engine.

To help you navigate the different model numbers, let's break down the basic structure of a John Deere lawn tractor model number. It usually starts with a letter that indicates the tractor's series, such as the D series for compact tractors.

The model number can also include additional letters or numbers that indicate specific features or upgrades, such as the presence of a hydrostatic transmission or a specific cutting deck size.
