    Backhoe hydraulics question please...

    We bought a used JD 2320 with a 46 hoe... great running tractor... when we come out in the morning, the stabilizers are halfway down and the backhoe "arm" drops to the ground... do you think there is a bleed problem or slow leak somewhere? This just started over the last few days, we have had the tractor for few weeks now.

    The tractor was built in 2008 and has 90 hours on it... thank you in advance... Andrew

    I believe some amount of leakdown is normal. In another thread, someone commented that they don't use as expensive cylinders on these tractors as they do on the commercial heavy equipment, thus more prone to leakdown.

    My 48 backhoe has holes and a pin for transporting, or not using the backhoe. That keeps the boom up. I always use the pin, so I don't know how much the boom would drop overnight. My stabilizers drop less than 1/8 of the way down in 2 days of non-use. (That's about the longest I've gone without using the tractor.) I just pick them up again. Other posters have even put bungees on them to hold them up. I guess it doesn't take too much force to hold them. My bucket drops down a bit, too.

    My unit is a 2001 and has about 480 hours now. Maybe someone else can give you a better idea what's a "normal" or "acceptable" amount of leakdown.

    Sounds normal, unfortunately. There should be a locking pin on the "arm" (actually called the boom) a short chain between the stabs will keep then from falling and causing damage to anything in their path.

    Agree with all this is normal, different machine leak down at different speeds.

    One thing to consider: If you leave a machine parked with the boom up, loader up, or stabilizer up and someone moves a control lever, that part will move. Every kids I've ever seen (ages 5 to 50) seems to be built such that when they see a lever, they pull it. So I park my backhoe with the boom down, bucket resting on a piece of wood, and park it with the loader bucket down, resting on two pieces of 2x4s. This gets the safety thing, avoiding squished kiddies, and avoids your parking the machine somewhere and then later finding something came to rest where it shouldn't (like the stabilizers resting on the fender of your garden tractor).

    My stabilizers take a week to move 6", so I don't put them down but I do park where they could come down. They also don't drop with a "bang" like the other stuff. That said, if I'm giving a tour of the shop I put them down. And in the future if they leak more I'll put them down on a piece of wood.

    I guess I've described the lazy mans version of Kenny's boom transport pin and chains... I also have everything indoors so having the cylinder exposed is not a concern. For outdoor parking, I'd have everything in and chained up.

    Thank you very much all... appreciate the advice.

    We do have a pin for the boom... will use it for now on during rest. We did use it for transportation.

    Ours has done this since day one and leaks down much faster than my old JD650 and the 650 had the #7 hoe. Wish the 2320 had the #7 hoe.

    guess it's something we all have to live with. I am glad you guys affirmed that it's "Normal"... nothing worse than something major happening in the field when work needs to be done...

    If it weren't for this forum, I would have brought it to the JD mechanic and spent a lot of money for nuthin'.

    That's one of the great things about these forums. We can learn from each other, and find out if others have had similar issues and experiences. It's certainly worthwhile to get someone else's opinion before taking your tractor to the dealer and paying big bucks for service.
