A noisy feed drive hydrostatic system in a JAG 940 can exhibit various sounds, and each sound may point to different causes. Some of the most common noises operators report include:
- High-Pitched Whine
- A high-pitched whine, often heard when the machine is in motion, may indicate that the hydraulic pump is cavitating. Cavitation occurs when air enters the pump, disrupting the fluid flow and causing inefficient operation.

Several factors can contribute to a noisy feed drive hydrostatic system. Identifying the root cause is critical for preventing further damage and ensuring the smooth operation of the machine. Below are some of the most common causes of noise in a hydrostatic system:
- Low Hydraulic Fluid Levels
- One of the most common causes of noise in a hydrostatic drive system is low hydraulic fluid levels. Insufficient fluid can lead to cavitation, which disrupts the normal flow of fluid within the pump and motor. This condition not only generates noise but can also lead to overheating and excessive wear on system components.

- Improper Fluid Viscosity
- The viscosity of hydraulic fluid plays a critical role in the system’s performance. If the fluid is too thick or too thin for the temperature or operational conditions, it can cause excess friction, increased wear, and excessive noise. This is particularly common in machines that have not been serviced with the correct fluid type.
