Hydraulics question

[OlFerguson]

I checked my hydraulic dip stick on my tractor and noted the milky hydraulic oil in it so I plan on flushing it all out and changing my filters and replacing the oil. How does water and contaminants get in there ?? Any ways to prevent it ? Thanks

You defiantly have water in there, not good!

Is your machine left outside? If so - various ways moisture can get in there.

If not left outside......then it must be condensation and this too would be a problem, but much harder to get into the works, unless the dipstick was left out, or the suction line had a small crack in it.

Need to drain, and then maybe fill and DRAIN again, not good on the pocketbook for sure! Change filter both times too!

Yeah, it’s stored outside . I need to build a barn for it .... oil is not cheap .

Usually condensation.It also indicates low usage. If you use you tractor for any length of time, the transmission oil will warm up and water will evaporate Damaged boots at the bottom of the shift lever(s) can let water in also.
