    3pt newbie question

    Is it normal for the 3pt arms to leak down overnight? I don't have a rear implement on it, its just sitting in the garage. I noticed it a couple days ago.

    Not sure if this a issue or something that is normal.

    Thanks

    No, it isn't normal. They should stay set exactly where you leave them.

    Good thing i got the extended warranty. What is generally the cause of this, bad seals in the rockshaft valve leaking off...or...?

    Over time, and depending on the load both the three point hitch and the loader may leak down. It's considered acceptable within certain parameters. JD has published leakdown rates for the loaders that are considered 'in spec', but I haven't seen such for the three point.

    It might be worth a call to the dealer just to have it checked out.

    When my 1026R started doing that I took it to Deere dealer. They found a small amount of rust on an internal valve and a large score on the internal lift cylinder for the 3 point. I have a thread on it someplace.

    If I put mine away with the oil very warm from mowing it will leak down.. If I just run the tractor for a few minutes, mine stays up all the way with my hitch on it.

    I figured the viscosity of the hyguard thins out enough when it is hot that it leaks down faster and must leak down all the way before the oil cools, but cold it doesnt leak down hardly at all. Any opinons on if I should take it to get checked out? I was blaming the low vis hyguard lol.

    Mine did not leak down no matter how much I used it. Then it got the crud in it and had to be replaced. My tractor can sit for a week between mowing and I know my hitch doesn't move when I start it up. Seems like it should at least be checked out. If you call your dealer they can tell you how much leak down is acceptable with JD.

    I would say the 3pt and the loader should not. However, the loader on most of the JD small tractor models will because IMO JD is using cheap parts.

    According to the TM, the rockshaft is allowed to leak down 2" in ten minutes with the engine off and warm oil.

    That test is actually testing the function of the drop-rate valve though, no?

    I mean, the whole idea there is to make sure the drop-rate valve actually opens and allows the arms to drop. That's why they have you fully open the valve in the test.

    If the valve is closed then there shouldn't be any (or only very little) drop.
