Hydraulic oil

[LD1]

Do hydraulic functions all work fine? Or are any of them jumpy from time to time. A small pinhole on a suction like would cause tiny air bubbles in the oil and would make it cloudy

any way to syphon a little of the oil out into a clear jar to see what it looks like? If air you will see the tiny bubbles, if water you should see the separation at the bottom of the container. For me Pulling drain plug usually just makes a bigger mess..

Air inleakage a definite possibility. From filters? Stuck gasket from old filter on housing? Wrong spec filter? Loose center pipe on filter housing? Leak from from suction line connections? Cracked rubber on suction lines?(this happen on my low hour Kubota B26) Sometimes air inleakage leaks will not drip when parked.

Not sure where your observations are being made on the hydraulic fluid. Does your tractor have a sight glass for hydraulic fluid or is this all coming off dip stick observations. Unlikely on a new tractor to get any water into hydraulic lines, other than a very minor condensation contribution.

I am thinking your just seeing air foaming of the hydraulic fluid occuring in the hydrostatic case which makes it appear milky. And then after shutoff, the air bubbles leave the hydraulic fluid, resulting in a clear fluid. I see this occuring all the time in automatic transmissions on cars and trucks, where high speed usage foams the fluid with air. Just make sure your hydraulic fluid levels are all at proper levels.

Take a sample of the oil after runing it to get the oil mixed up well. It will show whether it as air entrainment or water contamination. Does not matter the sample comes from the transmission, or a loader hydraulic line. Until then, it's just speculation.

If that is a sight glass you may have overfilled the transmission.
