I have a M7040HD1 that has had lots of noise from the engine and hydraulics from the day I purchased it. The dealer has been good to work with but they don't have more ideas. They have isolated the hyd lines replaced the oil with super UDT (this made a huge difference in general noises ) . They replaced the oil cooler with a new style that dose not have a bypass valve around it . But once you here a noise it is hard to forget it. It is mainly at a idle and sounds like 2 blocks of wood hitting together very fast for 10 seconds this will happen every couple of minuets.

The factory has sent me a letter saying it is normal and the noise is coming from the relief valve on the oil cooler that has been removed. Has anybody else had noise complaints I have been watching this forum for almost a year now and haven't seen anybody else with this problem

Here is the letter they sent me

I clicked on the link and was directed to another tractorbynet page that said it was an invalid link. I get the thumping noise in my MX5100 HST when I lug the system in high range, but that is the only time that it happens.

The last time I talked to him, he was getting a different tractor; John Deere 6000 I think.

Thanks for the reply. Do you know if they solved the problem ?

I am in the same boat as I paid good money for this tractor. My last tractor cost me several thousand to repair the hydraulics when the pump failed. that is why i bought this tractor and it is concerning me now that it will fail to .

do you know where the rep was from that looked at his tractor? the rep that looked at mine was from Decatur IL.

can anybody with a m7040HD look at your hydraulic cooler in front of the engine and see if it has the bypass valve around the cooler or if all the flow goes through the cooler

I sure don't remember, I have deleted the correspondence. The last I heard from him, he was looking at a 6000 Series John Deere and he hasn't posted here in quite a while.

Does anyone know if this problem was solved on the current tractor or if there was a cut-off date when the problem was solved? A friend of mine is considering a new M7040DT and I would hate for him to have a problem, especially since I helped steer him to Kubota.

Check with canoetrpr, GWDixon, Builder and Native Son, they all have M7040's spanning from several years old to brand new.

I believe that they have had this for some time seems like the rep mentioned a tractor that was 2 yrs old with this problem

I don't have a manufacturing date on mine but it was still in the crate when I bought it in February 2011

How do they expect us to be able to sell a tractor that makes this kind of noise?
I know I would not of bought it!
