Posted on here last week about my 4320 making a hydraulic noise under the dash. Took the hood of and checked all the lines for rubbing and found nothing. Went and mowed hay with it but left the cowl off so I could feel when it was making noise to see where it was coming from. It happens when I idle the tractor down to around 1200 rpms and it is coming from the large line that goes into the bottom of the pressure control housing. I can feel it making the noise and when I pull on the line it will kind of go away but as soon as I give it throttle it goes away. And it is kind of like a slithering sound kind of hard to describe any ideas? I have attached a picture and it is line number 6 that I am referring to.
