M7-131 Hydraulic whining

[jlindsly]

My m7-131 does not whine at an idle. But if you have any RPM's on it and lift the or tilt the loader I get a pretty bad whine. Is this just the big pump or the load sensing, or is this something I should get checked out. It seems to function properly. However, I just bought this tractor and what seems proper to me might not be.

Warranty? Dealer? if you bought it from a dealer have them check it out.

Bought it used. difficult finding out if it still has warranty. Going to change all of the filters and see if maybe there is a restriction there. I had a dealer tell me that if the previous owner put non UDT oil in it, it could cause the same problem. After some digging I find that this tractor does not use the UDT or UDT2. It uses UDT HD.
