Hydraulic problem with Bush Hog FEL.

[Seybert]

When lifting the bucket I get a noise in the lines going to the cylinders. Have no loss of power lifting or no loss of speed, just a noise that came on suddenly. There are no leaks and have only about forty hours on the fluid and filters. This doesn't interfere with performance but could lead to a problem. Any help or ideas would be appreciated. The loader is on a Kubota M4900 with 600 hours on the tractor. Thanks

Can you explain the noise?

Install a hyd gauge and see if it is the relief valve.
