NH TD5.65 2 wheel drive - do I have a problem?

[cyffylog]

Hi All familiar with NH. Whilst mowing this year after about 2hours I became aware of a slight 'clunk' and felt a knock each time I used the brakes at a corner, never noticed it before, but that's not to say it wasn't there!. I probably felt the knock first and listened hard to try and identify the source.

On finishing the job I experimented a bit and :-
1. the clunk whilst still there is not particularly loud and you have to listen intently to hear it over the engine noise.
2. It's only the R brake produces the clunk.
3. If I move the single Auxiliary Control Lever to the release (allow oil to return to the system) position, the clunk is absent.
4. Both brakes seem to be working properly.

Am I worrying over something that was always there, or is this a portent of future trouble and should be investigated by an experienced NH mechanic?

Any advice please.

Loose wheel nuts maybe-hopefully

Sounds like it’s related to hydraulics, the draft lever isn’t right at the top is it?
It doesn’t sound worrying.

Thanks both for your responses. No the wheel nuts are all tight, and the noise occurs when stationary as well as on the move. also, as Chris says, it is definitely related to the hydraulic system because it is affected by moving the Auxiliary Control lever to the down position.
The draft lever is in the down position, as is the position control lever, but neither have any affect on the noise.
As you say, I am probably unnecessarily bothering over something which is normal and may have always been present.
The 2016 tractor, which I bought s/h a couple of years ago, is rarely used, shows only 1035 hrs, 30 of which are mine!
