Backhoe BX22 Backhoe question

Rick Jay · Apr 14, 2003

Well, the warning wasn't so much as in regards to the weight that can be lifted. Rather, they made specific reference to the fact that the backhoe is hydraulically operated, and that a loss of pressue due to a ruptured line would cause the load to drop immediately without warning.

Of course...we still do it, but it's a good reminder not to have anything valuable under it at anytime. Ever.

It is quite interesting to look at a load chart (lifting) for a back hoe or excavator compaired to a crane.

I'd rather scoop with the backhoe to backfill or use the FEL 

My Woods hoe doesn't say not to do it, but I usually don't. It is usually much easier to use the FEL.

.....( Well, the warning wasn't so much as in regards to the weight that can be lifted. Rather, they made specific reference to the fact that the backhoe is hydraulically operated, and that a loss of pressue due to a ruptured line would cause the load to drop immediately without warning.

I'm not quite sure how a line could be ruptured. Unless you are trying to move a huge pile....if that's what this is still on. On my case backhoe, we use the side to side motion all the time to even/flatten things out. I could see how it's not recommended on such a small backhoe like the BX2200 though.

Blake,

( I'm not quite sure how a line could be ruptured. )

You've got more experience on heavy equipment at your age than I'll have in my whole life, so take that into consideration as I anwer this. I was referring to using the BH as a crane for lifting. Any hydraulic hose or fitting could fail at any time. There have been posts by other TBN members attesting to this. As you age, you begin to see that "stuff happens"...for real...and when you least expect it or want it to. Often called "Murphy's Rule", and most of us here can state that Mr. Murphy tends to show up and gawd-awfullest times. /forums/images/graemlins/crazy.gif

I just want others to remember to use caution around this equipment in general, and hydraulic equipment specifically.

As far as using the BH to swing dirt back into the hole, I've seen it done all the time if the loader can't get in position to do it. I just don't see why it could be a problem, unless for the 3 pt. mount backhoes it puts too much lateral stress or twisting on the 3 pt. hitch mounting. /forums/images/graemlins/confused.gif

Thanks,

~Rick

You know, one thing that is different between "real" heavy equipment and the stuff we use is that the commercial stuff is maintained to a whole different level. When you are using something that weighs 40,000, 60,000lbs or more you get real serious about making sure it doesn't break, especially since you are working in a public place or for a customer. On decent sized jobsites, there is a maintenance truck out there every single day.

So my thinking is that, for example, on my tractor I'm sure it wouldn't hurt to change the hydraulic hoses. They aren't falling apart, but they sure don't look new any more. But for me, I'd just as soon not mess with it until I have to (and hope I don't get nailed in the face with a high pressure stream /forums/images/graemlins/tongue.gif). I'd guess the big boys replace 'em every year (or even more often) whether they need it or not.

Besides, they have health plans and such. We are just doing it on the side, so it makes sense to assume that equipment will fail. /forums/images/graemlins/ooo.gif

 I just don't see why it could be a problem, unless for the 3 pt. mount backhoes it puts too much lateral stress or twisting on the 3 pt. hitch mounting. 

Yet another reason I favor the sub-frame models for these little tractors...

Oh okay, that makes more sense. I thought you may have been refering to that....My boss had his backhoe do that one time I believe, he was loading his truck up with the hoe and the stupid hose broke and lost it's power INSTANTLY. He had to bring our backhoe (the one I use) to lift the hoe off of his door that he THAT ONE TIME left open for a few minutes. I've always had that fear of having the loader arm do that when I'm loading customers but nothing has happened yet. /forums/images/graemlins/wink.gif I seem to know Mr. Murphy pretty well. He has a thing for me I think /forums/images/graemlins/blush.gif Always around when I DON'T need him!! Although luckily he's stayed away from me while working on the backhoes.

As for what Chris said: we don't change our hoses until they need to be (like what you said). Some look really bad, but my boss said that sometimes the worst hoses do best. He's had perfectly new ones bust on him. Go figure! LOL.

Yeah, that is not supposed to have 2 zeros at the end. I get mixed up. Besides the B20-21, L35, and L48, kubota gets confusing with all their numbering for their machines.
