How to Adjust a John Deere F525 Mower Deck Front to Back

The John Deere F525 mower is a riding lawn tractor made by John Deere that relies on a level mower deck. If the mower's deck is not level, grass will be cut unevenly and your lawn's appearance may suffer because of it. There is a nut on the lower assembly of the mower deck that controls the raising and lowering of the mower deck from front to back. You can adjust this nut and level out the mower deck of your John Deere F525 mower regardless of your experience with leveling mower decks.
