    hydraulic deck bleed down?

    so i have a new x590 and over night the deck is of course in the raised position, but the next time i get it out it has dropped to the cutting level. so is this normal for the x500 series to do this with the hydraulics or is this an issue?

    This is normal. I have owned several different garden tractors since 1984 that had hydraulic lift decks. All the decks would settle in a short period of time.

    Other folks have posted this happens to them as well. I don't know what the difference is but I have an old 332 and it does not bleed down. It seem to me this bleed down would be real annoying. I have areas that I cut higher and if i raised the deck only to have it drop by itself before completing that area it would be annoying to me to have to keep raising it and hope i was consistent with the cutting height.

    When i park it I raise it up all the way while pulling onto the concrete pad that is slightly higher than the stone apron and it remains all the way up until the next time i pull it out which could be a week later.

    It doesn't bleed down when engine is running and there is pressure in the hydraulics. It only bleeds down if the engine is shut off.

    If this is the case then it's normal. If your deck drops while the engine is running you have a problem.

    yeah, only when stored/engine off. never issue when on/cutting. i'll mark this down as completely normal. just thought it was strange that it "leaks" down w/out any actual external leaks. perhaps the reservoir creates this as a pressure loss/gain area for it to escape to.

    Ok.. On the newer units the deck lift is a single acting cylinder. It and the valve that controls it,was never meant to hold the deck up. That's the job of the height control knob.
    On the older machines, it was a dual acting cylinder. Power up.. Power down. They will, for the most part, hold position. Do not confuse the two. And in some cases, even a new machine will not hold the deck up even with the engine running if traveling over rough terrain.
