My hoe has the dropsies.

Hey now don't waste those...

Every one is a little different, but this doesn't sound abnormal to me. Was it always like this or has it gotten detectably worse in the 10-15 hours you've used it?

Only time my BH75 droops is when I repeatedly use the rear remote valve for a loader attachment. The droop is minor but I either have to pin the boom or reach back every 30 minutes or so. Left up when parked it will not move for days.

The outriggers will droop over over a period of days.

Does the Woods BH droop?

Does the Woods BH droop?

Sure does. Maybe not as bad as these guys' BH75's by the sound of it, but then maybe more so than yours. I honestly can't say I ever timed it though. It varies with a couple of factors like, which bucket I have on it, did I leave it parked in the hot sun, etc. It will always droop a couple of inches in a half-hour or so, then it plateaus for a while (think as if there were some "play" to be taken up). I'm going to guess after it hits that plateau it droops less than an inch an hour. This is only the boom, the stabilizers aren't as "droopy". The BH80-X boom is more massive than the BH75, plus I got that thumb on there, good bit of weight to hold up.
Bottom line, as long as it doesn't droop while I'm using it or start losing its craning ability, I'm not going to worry about it too much.

Just about every thing that uses hydraulics, will leak down over time with a load . Hydraulic tables to backhoes, etc. It may be the cylinders, or the valves. Manufacture quality control is just one factor, and then you have parts and tolerances. Some better than others. It is always safer to lower all hydraulic equipment when finished . I have even seen bush hogs left in the up position with kids playing around them.

Does the Woods BH droop?

My BH9000 does, but nothing like some of these guys are talking about. The droop rate also slows as if goes down - the boom will drop far enough that I can't stick in the transport pin inside of a couple of hours, and I might see an inch of boom piston shaft overnight, but would take at least a week or two for my bucket to droop all the way to the ground. My BH9000 is fairly old and well-beaten too.

I understand that minor drop is normal, something like Jay4200 is speaking of, but to drop enough to have to reach back and give it a boost every 30 minutes is too much I think. It didn't drop any at first for several weeks.

Spoke to dealer today and will be taking it back Monday. He acted like he was going to fix the thing and make it right. So stay tuned if you are interested in the outcome. I'll post the results as soon as I know something.

yes, I'd be interested if they do fix it, and if what they did actually helped. Although I'm out of warranty now, although i did have it to them at 10 hours for the problem. I cann't say its gotten much worse though since then. If i forget pin, i'm reaching back every 15-20min though with about 4" drop.
I'll probly live with it if not warranty but would be good to know exactly what they might find.

Just out of curiosity, where is that 4" measured? Is that bucket height from the ground, or exposed boom piston shaft?

ground to bottom of bucket. cylinder is in boom, so i never get to see the piston.

Good question, we might not all have the same point of reference. In my earlier posts I was referring to highest point of the boom with respect to ground, tractor, whatever else. In other words, the tip-top of the dipper knuckle. Why there? When I'm on the tractor it's something I can easily see...when I raise the boom I can gauge how much the top of it dropped. Because of the boom angle, the top also moves further than the bucket when tucked in.
Someone else might be thinking the amount of boom rod exposed... not to sound like Capt. Obvious here, but that translates to at least twice the amount of boom or bucket droop.

Well, got my answer today. The dealership checked all the leak rates and then contacted their tech support from the factory. The factory said that they allow 2 inches every 5 minutes bleed down. The dealer agreed that seemed like quite a bit, but if that is what they call normal they can't do anything to fix it. I don't like it, but I'll have to live with it I guess.

Here is the first strike against my machine. Hopefully there will not be many more.

Bummer... I'm surprised to hear they allow that much. Hopefully it doesn't get any worse... or maybe we should hope it gets ALOT worse so it will get fixed!

I took delivery of a GL3240 w/ BH90 back-hoe on Aug 16th. I now have 46 hrs on it. About half of those hours were back-hoe work. The delivery guy pointed out that the BH90's stabilizers had bled down a bit during the roughly 1 1/2 hour trip. The stabilizers had spread out a few inches. The tractor had been loaded with the hoe bucket on the deck of the trailer so I don't know whether that would have bled down too.

The BH90 always 'relaxes' a little while I do FEL work or when left fully tucked up at night. Nearly every cylinder bleeds down a little (bucket, dipper, boom and both stabilizers). During FEL work I occasionally (every 30 min or so) check the BH. It nearly always needs some tucking (a inch or two per cylinder). Over night relaxation is less predictable. Some mornings the BH bucket is on the ground. But most mornings it has relaxed about the same amount as during FEL work. IOW it seems that the BH90 has a preferred 'relaxed position' that it assumes within 30 minutes or so. Then (usually) only relaxes further over a much longer period 8-12 hours. I'm not sure what to make of this. It appears that the _whole_ BH loses pressure not just one or more of the cylinders. Of course I've looked for leaks and found none. All of the fittings stay dry.

BTW one of the nicest things about the reclining seat is being able to lean it all the way back and easily reach the BH controls I always set/lift the stabilizers from the drivers seat so they are out of the way when entering/exiting the operators console.

OTOH the LA 724 loader is rock solid. I've left it in the air over night several times and would need a measuring tape to tell if it moved at all

Man this question shows up a lot here.

All a dealer is going to do is check for external leaks. Spool leakage is unavoidable and nobody is going to spend the coinage for a new spool (which will probably do the same thing anyway).

Set it on the ground at night, pin it when operating.

That is all.
