Assuming of course you have changed the filter? Do the hydraulic functions seem to operating as usual or are you noticing anything strange on that front? How about steering? Is that reservoir full and the steering working okay? If you run the tractor until you hear the noise, shut it off and pull the hydraulic dipstick do you see any evidence of air or foam building in the fluid?
