Help with Noise From my 2025R While Driving

It’s a harmonic resonance thing with one of the hard lines coming off the pump. Atleast on mine it is. I had a tech actually visit my house back when I only had a couple hours on it and look at it and said it was fine and to run it. If it grenades than its covered under warranty. It really unsettled me and I was constantly keeping an ear out. I have since become immune to it and it has not lost any performance or had any weird stuff happen.
It happens when it’s warmed up and after putting ear buds in I don’t hear it anymore lol.
I and a couple others have posted threads on this and it seems to be a not so common issue with these smaller pumps on the 1 and 2 series.

Just to make sure your issue is the same as mine, get the machine warmed up and work it until it starts to whine. Get off while it’s still running and with a glove on your hand grab this line and squeeze.

If it dampens the moreyou squeeze it’s the same issue.
One of the members had replaced this hard line with a rubber hose and got the noise to stop.
I have gotten used to it and am not worried after over 400 hours if perfect performance.

I think I posted this somewhere here previously, but my 2025R did the same thing. It bugged me a lot. My sales guy at my dealer was able to find some sort of publication from JD that listed a part number for a soft line replacement. I replaced the hard line with a soft line and it solved the resonance noise. If you're interested, let me know and I'll see if I can find my post or a part number for you. It wasn't difficult to replace but the seat had to come off. I did have someone comment that they'd never replace a hard line with a soft line, but for me I hated the sound enough that I was willing to try anything...and if Deere makes the part I figured it should be ok.

The only reason for the hard line is the path of it in close proximity to other vital equipment. Under the pressures these lines endure, soft lines will flex and move around. This can be solved by zip ties and such in most cases.
I had a hard line on an excavator fail on me a few years back. Tech comes out and pulls the hard line off. He replaced it with a temporary soft line while the new hard line went out to get made. This went on for a month or so until the hardline was done and put back on. I asked the tech how long would the soft line hold and he said indefinitely as long as it doesn’t chafe a wear hole in it.

I would be interested in your thread and part number if it’s not too much trouble

If the hydro fluid is over full, I would resolve that immediately by drawing out the excess fluid. Over filling a hydraulic system can cause heat and affect fluid pressure, etc and lead to possible damage. Now that you have the machine and are using it, and have hooked up the hydraulic implements to make sure the hoses and lines are all filled, I would establish the correct fluid level on the tractor by drawing out excess fluid.

For those that are interested. Here is a link to my post that shows the new soft line and part number. Fix for Hydraulic Hard Line resonating (2025R)

Thanks for the info. Just looked on GPS & they have it priced at 99.24. Also looked up the parts catalog usage & it seems to be an option like you say between having the steel line or hose.

If you look at any excavator, bulldozer, or anything else that has to articulate they all have 'soft lines' at some point in their plumbing to accommodate movement of the boom, etc. IMO, the manufacturers don't use hard lines because they are necessarily stronger. They are probably easier to manufacture and cheaper than a similar soft line rated at the same psi. As long as precautions are taken against chafing/rubbing against other assemblies, I wouldn't loose any sleep over it.
Thank you for sharing your solution to this problem
