John Deere 950 Problems [3 Common Issues & Fixes]

The John Deere 950 tractor has long been a reliable workhorse on farms, known for its durability and versatility. However, like any piece of machinery, it can encounter hydraulic issues over time. In this article, we will discuss some common problems with the John Deere 950’s hydraulics and explore possible solutions. Whether you’re a seasoned farmer or a tractor enthusiast, understanding these issues can help you keep your 950 running smoothly.

John Deere 950 Problems: 3 Common Issues

Problem 1: Unstable Three-Point Hitch (3PH)

One of the reported problems with the John Deere 950 is the instability of the Three-Point Hitch (3PH). Users have noticed that the 3PH will raise but won’t stay in place unless the locking knob is tightened down. Additionally, it struggles to lift heavy loads, such as bales of hay, without assistance from the locking mechanism.

Possible Solution:

  1. Check for Leaks: Start by inspecting all hydraulic hoses for any signs of leakage. Even small leaks can lead to a drop in hydraulic pressure, affecting the 3PH’s stability. Replace or repair any damaged hoses.
  2. Clean Hydraulic Components: Thoroughly clean all hydraulic components, including the pump, filter, and connections. Remove any dirt, grime, or debris that could obstruct the system’s proper functioning.
  3. Pressure Test: Consider conducting a hydraulic pressure test. Low pressure could indicate a worn pump or other restrictions within the system. Refer to your tractor’s service manual for specific pressure test procedures.
  4. Seal Kit Replacement: If the pump is suspected to be the culprit, a seal kit (P/N CH14439) is available for the pump. This kit may help restore hydraulic performance without the need for a complete pump replacement.

Problem 2: Slow Loader Performance

Users have reported slow and weak loader performance on the John Deere 950. Even with the loader arms and bucket holding their positions, the lifting and reaction speed is sluggish. This issue is especially noticeable when attempting to lift heavy loads.

Possible Solution:

  1. Inspect Lift Cylinders: Slow loader performance may be due to internal leaks in the lift cylinders. Check for any visible signs of hydraulic fluid around the cylinders and consider having them inspected or rebuilt by a professional.
  2. Evaluate Pump Capacity: The original hydraulic pump on the John Deere 950 may not provide the desired speed and power for the loader. Consider upgrading to an increased capacity pump to improve loader performance.

Problem 3: High-Pitched Noise

Some users have reported hearing a high-pitched noise from the hydraulic system, particularly when it’s under load or minimal stress. This noise can be an indicator of an issue within the system.

Possible Solution:

  1. Relief Valve Inspection: The high-pitched noise could be related to the relief valve. If the valve is stuck open, it can cause noise and affect hydraulic performance. Consider inspecting and cleaning the relief valve or seeking professional assistance.


The John Deere 950 tractor is a dependable machine, but like any piece of equipment, it can face hydraulic challenges over time. By diagnosing common problems and exploring potential solutions, you can keep your 950 running smoothly and efficiently. Regular maintenance, inspections, and, if necessary, upgrades can help ensure that your tractor continues to serve you well for years to come. Remember to consult your tractor’s service manual and seek professional assistance when needed to address these issues effectively.
