The specifications for a John Deere lawn mower vary depending on the specific model of the mower and the year it was produced. As of 2015, John Deere produces a wide range of different residential and commercial riding lawn mowers.
The company produces four series of riding lawn tractors, which include 27 different models. The John Deere 100 Series lawn tractors range in terms of horsepower from 17 to 25 and are available in deck sizes from 42 to 54 inches. The X300 Select Series of lawn tractors ranges from 18.5 to 22 horsepower, while the X500 Select Series ranges from 24 to 25.5 horsepower. Several of the models in both the X300 and X500 series also feature other options, such as power steering and lift, four-wheel steering, and rear discharge and collection.
John Deere's commercial riding lawn mowers, known as ZTrak zero-turn mowers, are available in four different models, including the ZTrak Z900 B Series, M Series and R Series. The other model in this line is the ZTrak 997 Series, which features a diesel engine instead of the gas engine found on all other models. The company also produces 13 models of residential zero-turn riding lawn mowers, which range from 20 to 25 horsepower.
