Fluid power systems make noise for many
reasons. You could have a valve that
needs to be tightened up and it is rattling
against the tractor. But you probably checked
that already. You could have a noisy relief
valve, you may want to run the hydraulic
system through the pressure ranges hi-lo
etc. that will exercise the spring in the
relief and maybe get rid of the rattle.
Or you could have to small of hoses and
connectors on the system. A basic
rule of thumb, under 5gallons/min of flow
a 3/8" line works, 5-10 gallons/min of
flow use a 1/2' and between 10-15 use
a 3/4" line. over 15gpm you may
need to go to a 1" or larger. You will
also need to isolate the sound. Is it the
cylinders, valving, pump, connectors, linkage.
First thing I would try is to lower the
hydraulic pressure and see what happens.
