What Size John Deere Mower Deck Do I Need for My Yard?

As a general rule of thumb, yards under 1/2 acre generally have 42" or less decks. 12/ acre to 2 acres have decks with 42-54" decks. 2+ acres have 54"+ decks that can be as large as 72".

Choosing the right mower deck size helps you mow efficiently without sacrificing cut quality. Here's how to match your yard to the right John Deere deck, with tips from Koenig Equipment.

  • Yards Under 1/2 Acre: 30-42" deck (S100 Series, X300 with 42")

  • 1/2 to 2 Acres: 42-54" deck (X300, Z300 Series Zero-Turns)

  • 2+ Acres or Large Open Spaces: 54-72" deck (Z500 Series or X700 lawn tractors)

  • Consider Obstacles: Narrow gates or trees may require a smaller deck for maneuverability.
