JD 4610 honking/squeaking noise at startup

[rkncirclec]

When I start my JD 4610, I have a honking noise coming from the left side of the tractor next to the hydraulic filter.

Operationally, everything seems fine. No leaks. I did not run over a chicken or duck. But it feels like a pump is going.

Any help appreciated. I'd rather fix it myself than pay the man.

Thanks

Maybe change the hydraulic filter.

I replace the hydraulic filter, cleaned out the suction filter, replace the tranny filter, all new hyro fluid.

Can you make a video?

My 4310 does the same sound. It is in the hydraulics. I believe the sound is the pressure building against the valves as it pressurized.

Any adverse effects so far?

thanks

Mine has been like that for at least 500 hrs. Everything works fine.
