    Water or Air Frothing in Hydraulic Oil

    First photo right after shut down. Second photo 10 minutes later. Should I drain and replace? Is this water or air? Thanks.

    Try the sizzle test. Take a small sample (a teaspoon or so) and dump it into a hot frying pan. If it jumps around and bubbles and steams, then you have water. If it just spreads around and doesnít do much, then no water.

    Would you take it from the drain or suction it out from the top? I drained about 1/2 gallon out the other day and did not see any water in it. Thanks.

    Doesnít matter if you do it right after using it. I suspect you donít have an issue at all. Youíre probably just seeing the normal aeration that happens during normal operation. But you asked, and I canít be sure. The test will tell you if you have water or not.

    Not saying you may or may not have any water but, it certainly looks like any other sight gauge Ive seen when a machine is in use.

    Granted I have a 2720 with red dye in the fluid but I have a similar sight glass and my fluid always appears crystal clear (with dye) even immediately after shutting the tractor off. I never see any discoloration or cloudiness.

    Sizzle tested alongside new oil from jug as a control. One or two very slight almost imperceptible pops from my tranny oil and none from control jug oil. Shook up jug oil and it also traps tiny air bubbles which contribute to opaque or milky appearance and settles out in the same time frame so I suspect the problem is a slight amount of moisture along with product naturally trapping microscopic air bubbles. Moisture might just be from natural condensation.

    I guess Iíll shell out the price of a fluid and filter change so I can sleep at night. I really donít like not having a dip stick on this model as that window does not seem to be very accurate. Level has been changing up and down since last fluid change about 60 hrs ago.

    Tip: last time I used a magnetic pick up tool on an extension wand to run in the suction screen housing by the drain plug to pick up metal shavings that the magnets in the screen had missed. Also used it to help clean out the inside of the suction screen. Just had very small filings.

    If you read this and have a 2320 does your sight glass go empty when you crank up and refill within a few minutes of shutting down and does the fluid appear creamy and opaque as soon as it refills the sight glass only to clear up in under ten minutes.

    Just curious, but to you regulary use the tractor for short periods of time and shut it down before getting the tranny up to full operating temperature so as to burn off any condensation?
