John Deere zero-turn mowers are known for their excellent maneuverability and speed, making them a popular choice for many homeowners and landscapers. However, like any mechanical equipment, they can experience problems over time. One common issue is when one side of the mower stops working, leaving you unable to turn in one direction.

John Deere Zero Turn one side not working

If you’re experiencing this problem with your John Deere zero-turn mower, there are several potential causes that you can investigate.

  1. Hydraulic Fluid Levels A lack of hydraulic fluid can cause one side of the mower to stop working. Check the hydraulic fluid level in the reservoir to ensure that it is at the proper level. If it’s low, add fluid as needed.
  2. Hydraulic Hoses The hydraulic hoses on your John Deere zero-turn mower are responsible for transferring fluid from the reservoir to the drive system. If a hose is damaged, it can cause a leak or prevent the fluid from reaching the drive motor. Check all the hydraulic hoses for leaks, cracks, or other signs of damage. Replace any damaged hoses to restore proper function.
  3. Drive Belt The drive belt is responsible for transmitting power from the engine to the drive motors. If the belt is worn, damaged, or has slipped off the pulley, it can cause one side of the mower to stop working. Check the drive belt for signs of wear, such as cracks or fraying. If it’s damaged, replace it with a new one.
  4. Wheel Motor If the hydraulic fluid levels and hoses are fine, the problem may lie with the wheel motor. A failed or damaged wheel motor can cause one side of the mower to stop working. To determine if this is the problem, lift the mower and inspect the wheel motor on the affected side. If it’s damaged, you’ll need to replace it.
  5. Electrical Issues If none of the above solutions work, it’s possible that there is an electrical problem with the mower. Check the wiring and connections for any loose or damaged wires. If you’re not familiar with electrical systems, it’s best to bring your mower to a professional for inspection and repair.
