John Deere L120 Electrical Problems

Electrical issues are another common problem faced by John Deere L120 owners. One of the main issues is power loss during mowing, which can be frustrating when trying to maintain a well-kept lawn. Additionally, blown fuses are frequently reported problems that can leave you without a functioning mower.

The power loss experienced during mowing can be attributed to a couple of factors. One possibility is cutting too much grass at once, which puts a strain on the mower and causes it to lose power. Another potential cause is debris and grass clippings getting stuck under the mower deck, obstructing its movement and resulting in power loss.

To resolve the power loss issue, there are a few steps you can take. Firstly, when dealing with tall or thick grass, it’s advisable to lift the mower deck slightly to reduce strain and maintain optimal cutting performance. This can alleviate power loss and ensure a smooth mowing experience. Additionally, regular cleaning of the mower deck is essential to prevent debris buildup and maintain proper airflow for efficient grass cutting.

Blown fuses are another electrical problem that John Deere L120 owners may encounter. When a fuse blows out, it disrupts the power supply to the mower and renders it inoperable. To address fuse blowouts, it’s crucial to check for wire damage in the power take-off (PTO) system, which is responsible for transmitting power from the engine to the mower deck. If any wire damage is detected, it should be repaired or replaced by a qualified technician.

When restarting the mower after a blown fuse, it’s important to keep the PTO clutch disconnected to prevent further damage. Once the fuse has been replaced, the PTO clutch can be reconnected, ensuring the mower is ready for use.

John Deere L120 Excessive Vibration Problem

Experiencing excessive vibration while turning on the engine is a common issue with the John Deere L120. This problem can be attributed to various factors, including unbalanced mower blades, debris accumulation on the mower deck, or shifted sheaves.

To troubleshoot and resolve this vibration problem, follow these troubleshooting tips:

  1. Check the condition of the engine. If the engine is damaged or faulty, it may cause excessive vibration. If necessary, replace the engine with a new one to restore smooth operation.
  2. Inspect the mower blades for balance. Unbalanced blades can lead to excessive vibration. If any blade is damaged or out of balance, replace it with a new one.
  3. Thoroughly clean the mower deck. Debris and grass clippings that accumulate on the deck can disrupt the even rotation of the blades, resulting in vibration. Regularly clean the deck to prevent debris buildup.
  4. Examine the attachment of any additional accessories to the mower. Certain attachments may alter the blade’s motion, causing vibration. Ensure that attachments are properly secured and do not interfere with the blade’s operation.
  5. Divide the PTO (Power Take-Off) if needed. Dividing the PTO can help distribute the load more evenly, reducing excessive noise and vibration during operation.

By following these troubleshooting tips, you can effectively address the excessive vibration problem of your John Deere L120 and ensure a smoother and more comfortable mowing experience.
