New Holland Workmaster 40
In a nutshell:

New Holland Workmaster 40. Tractor has 52 hours on it. I bought it with only a few hours (brand new never sold) and the dealership installed a New Holland loader from another new tractor onto this one at time of purchase. I've had it six months now. Since new, it has made this noise with the first start-up of each day. Doesn't matter what the weather is like. Doesn't matter time of day. The first start-up produces this noise. The noise lasts 10 seconds or less, then goes away and doesn't return until the next day. Hydraulic filters have both been changed. Fluid is still clear to honey colored and at the proper level. I see no leaks anywhere. Pressure at the loader cylinders tested at 2,400ish PSI. Everything seems normal, but this noise is pretty loud each morning. Should I be concerned?

same tractor, different branding stickers, same problem. Still awaiting resolution.

Doesn't sound normal to me. None of my tractors have ever made a sound like that

It sounds like fluid ( most likely hydraulic) momentarily leaking past a seal. Since the sound dissipates so quickly, I wouldn’t worry about it.

I would guess that it is an o-ring that was either twisted upon installation or perhaps slightly cut and it allows leakage until pressure builds up on both sides.

That’s quite the battle cry... 😂
Hopefully it’s a simple fix the dealership can remedy quickly!
