17 Hours 4075r, It started making an odd sound. I needed to move 2000lb pallets of pellets and could not pick them up.

I went out to use the grader yesterday to repair parts of the driveway when it suddenly started making a very odd noise. From the cab, it sounds like you are dragging metal under the tractor.
I pulled the panels off and checked everything, including fluids and the belt. I crawled underneath and could not find the source of the noise.

Secondly, I put on the pallet forks today; the tractor hardly applied any lifting force.

I uploaded a video. If anyone would like to guess the extra noise you hear, the first 30 seconds of driving are just before you hear the sound around, which is at 31s. Increasing RPM while sitting does not create the sound. It does not matter which gear or if it is going forward or reverse.

My hearing is bad so not sure on sound but did you try lowering the 3 point a little and double check that all the rear remotes are in neutral or center position?

Why would rear remotes need to be in the center position to use the loader? My loader works no matter what position my rear remotes valves are in.

Loader hose connection(s) crossed ?

I have a 4075R making the exact same noise. The problem is it doesn't do it all the time so it is difficult to find. It is currently at the dealer for this issue. They replaced the front differential. The rock shaft cylinder was scored,

I have a 4075R making the exact same noise only worse. It is currently at the dealer for this issue. They replaced the entire front differential. It also had a scored rock shaft cylinder. After they get it fixed they can drive it and see if the front end was the problem. I will be following this post for sure. I hope it's not the main hydro pump, they already replaced the utility pump when I first got it. Thanks John

Why would rear remotes need to be in the center position to use the loader? My loader works no matter what position my rear remotes valves are in.

On some models of tractors with fixed displacement pump the loader valve supplies oil to the rear remotes and 3 point. All the valves are in series. Depending on the loader valve design the loader may have limited lift capabilities if the rear remotes or 3 point are also requiring pressure

If you have a variable volume pump it does not matter what position rear remotes or 3 point are in since the valves are in parallel.

Just wondering have you contacted your dealer, and if so what was the response. If both of us are having the same issue there may be others also. Maybe John Deere is aware of it.

The remotes are all correct; the RK was easy to do this on, but the JD returned to center.

They looked correct, the loader does pick up a bucket of gravel.

I got to the dealer very late yesterday evening with the tractor. But they waited for me; after driving the tractor, they, like myself, had no idea where the noise was coming from. I also told them about the loader, and they responded that they would check the specs.

This is a concerning situation, as we're now facing a backlog of work due to the 4075R's delayed arrival and issues.

It wouldn't hurt to have your dealer check on the front differential problem. My dealer has already replaced four, counting mine. It is difficult to find this problem because it has to be moving to hear it. The tech came over for the drive shaft sleeve replacement, took it for a drive and I could hear it 400 yards away coming down the road!

Kromc5 if it's not to much trouble I would be very interested in what your dealer finds out. Mine has been at the dealer going on three weeks, still no word on the problem thanks John

I will update the thread on what they find; I hope it's not three weeks. Our driveway is damaged, trees are down, and the storm has blown some gates off the hinges.

The dealer has not responded yet; I was contacted by JD CCMS out of Idaho today, and they are going to contact the dealer.

Thanks for the update and hope you get it fixed. They got mine back together today and we're going to take it for a test run. Must not have went well, they didn't deliver it

I hope that it is fixed. It would be interesting to see what they have done.

Maybe between the two of us we will get it figured out! When my tractor was delivered it already had 12 hours? Upon start up it sounded normal. After a couple minutes it acted like it came under a heavy load, it was twice as loud. I pointed this out to the tech, he just shrugged his shoulders and said I don't know. After my first episode of this terrible noise it no longer did it. Makes me think hydro pump.

I just got back from the dealer. They stated the sounds were due to the rear driveline shield being installed improperly. The bad part is that the hydraulic pump is not functioning correctly, and they may also have to replace the pump manifold behind the fuel tank. However, I will
ask for a copy of the repair work and upload a scan.

I am not sure what a rear drive line shield is, my front drive shaft shield got replaced and it didn't help the noise. Thanks for the update I will be watching. No word from my dealer. I usually have to call them. I don't want to be a pain in the arse.
