Power Steering Problems
Users of the John Deere 4120 have reported experiencing power steering problems. These issues can greatly affect the operation and maneuverability of the tractor. Some common power steering problems encountered by users include:
- Howling noise when turning the steering wheel
- Intermittent loss of power steering
- Leaking connection at the manifold
To address these power steering problems, there are a few troubleshooting steps that users can take. Firstly, it is recommended to check the hydraulic fluid level and condition. If the fluid is low or dirty, it may affect the performance of the power steering system. Replacing the hydraulic fluid can help alleviate the issues.
Another step is to inspect the power steering filter. A clogged or dirty filter can restrict the flow of hydraulic fluid, leading to power steering problems. Cleaning or replacing the power steering filter, if necessary, can improve the system’s functionality.
If these troubleshooting steps do not resolve the power steering problems, it is advisable to consult with a dealer or authorized technician. They have the expertise to diagnose and resolve more complex issues with the power steering system.
“The power steering problems on my John Deere 4120 were really frustrating. Every time I turned the steering wheel, there was this howling noise, and sometimes I even lost power steering completely. I discovered that there was a leaking connection at the manifold. Replacing the hydraulic fluid and checking the power steering filter made a significant difference. I strongly recommend consulting with a dealer or professional technician for proper diagnosis and resolution of power steering issues.”
| Common Power Steering Problems | Troubleshooting Steps |
|---|---|
| Howling noise when turning the steering wheel | 1. Check hydraulic fluid level 2. Replace hydraulic fluid if necessary 3. Consult with a professional if the issue persists |
| Intermittent loss of power steering | 1. Inspect power steering filter 2. Clean or replace the power steering filter 3. Seek professional assistance if needed |

3PH and Loader Issues
Owners of the John Deere 4120 have also reported problems related to the 3-point hitch (3PH) and the loader. Some users have encountered issues where the 3PH does not stay in place unless the lock knob is tightened. The loader arms and bucket also tend to lift and react slowly, with limited lifting capacity. Additionally, a high-pitched noise is audible from the connections when the machine is under load or minimal stress.
Some users have attempted to resolve these problems by replacing slightly damaged loader hoses and performing a complete drain and refill of the hydraulic system with a new filter. Unfortunately, these measures have not completely resolved the issues at hand. It is advisable for owners to seek professional assistance in order to accurately diagnose the root cause of these problems and find an appropriate solution.
Loader Issues Table:
| Problem Description | Solutions Attempted | Result |
|---|---|---|
| 3-point hitch does not stay in place | Tightening the lock knob | Temporary fix, but problem persists |
| Loader arms and bucket lift slowly | Replacing loader hoses | Partial improvement, but limited lifting capacity remains |
| High-pitched noise from connections under load | Complete drain and refill of hydraulic system with new filter | No significant improvement in noise reduction |
“I’ve tried tightening the lock knob on the 3-point hitch, but it only provides a temporary fix. The loader arms and bucket still lift too slowly, and the lifting capacity is not sufficient for my needs. I’ve also noticed a high-pitched noise coming from the connections, especially when there’s any load on the machine.” – John Deere 4120 owner
To address these issues effectively, it is crucial to consult with professionals who have expertise in John Deere machinery. They can accurately diagnose the underlying problems and recommend the appropriate course of action. Taking proactive measures to resolve 3PH and loader issues will help ensure optimal performance and longevity of the John Deere 4120.
