What's your hoe doing?

[aighead]

Welp, back to the drawing board!

I'm not intentionally being obtuse but what if the hole was on the inside of the blocks? Meaning a single row or two, where the outside was only 2 or 3 feet deep but the inside was 10. Like I set the blocks 2 high, then dig down past them on the inside. I imagine there may be collapse or sinking issues, but would that be the case if the exposed dirt was pressed back by the water (and pond liner held in by a fair amount of gravel)?

I'm not clear what you propose. One might dig a pond in native soil. If the sides are steep they'll migrate toward center. If not as steep, the weight of soil keeps it in place. In engineering they refer to angle of repose. If you see a pile of processed material placed there by a tall conveyor all sides of the conical heap are a straight line in a specific angle. This angle changes by a number of factors. In very wet slippery material this angle becomes a very slight grade. Wet concrete for example, nearly levels itself. Dry crushed rock might form a stable very steep cone.
Typical pond soil is going to be wet, pretty plastic. Gravity wants it to flow down. If it isn't able to flow down (there is soil beneath it) pressure moves it sideways.
To some extent water weight & pressure oppose this, but water isn't as heavy as mud.

Think of wet concrete. Wet concrete weighs about 175 LBS per cubic foot. A form holding wet concrete 1' tall has 175 PSF pressure. A form 8' tall has 1400 PSF forcing the form apart at bottom. Lets think of a cellar foundation full of water. The form inside walls would be opposed from moving by the weight of the water, about 63 LBS per cubic foot. At bottom of that 8' tall wall 500 PSF oppose that 1400 PSF of the wet concrete. Form only needs 900 PSF strength to contain the wet concrete.
Many a concrete crew have had tragic results when they failed to consider pressure rising as height of wall is great.

Whelp the loader lifted one of these with absolutely no trouble. I even drove one up my steep hill for a back stop on a rock screen I plan to set up. I excavated behind the garage a few feet but have had to excavate some large rocks where I plan to set the block. I will have to make sure I compact well when I fill the holes.

That’s kinda the main reason to put some stone in. Get rid of the big rocks, so the wall doesn’t heave.
When I do mine, the concrete place by me has some without the V so it’s like a cap block for the top layer.

Did you try lifting one with the backhoe? I have a tension scale that goes up to 10,000 pounds and hooked my backhoe on the 555D to a big old stump with chains to see what it could do. It managed a max of 4,500 pounds in the upward direction. I *think* it would lift one of your blocks, but not extended out very far.

No wonder you got fired.

There are many functions where you might measure lift. Backhoe boom might lift 5000LBS Use the dipper, you might lift 7500, use the bucket curl at mid position might be 8500.
This might apply to the loader. Case hoes, the bucket curl is more powerful than the boom.
I can lift 9500 with either end of my backhoe/loader, I have to use the most powerful function in combination.

 

[casey518]

The hoe would not lift the blocks with the chain connected to the bucket. If I tried to lift with the dipper it would overcome the boom even close in. I moved the chain to the thumb bracket and was able to lift with a slow drift down but only very close it with the boom almost vertical. Do you think its normal? Are my boom seals kaput, or aux releif valve set too low? Main releif valve pressures are to spec.

What machine is that?!

Mine was a simple test of *maximum* upward force, using any and all functions. I've never heard of a backhoe that could pick up that much weight using the backhoe for crane/lift.

This sounds normal to me other than the drift. Did that happen even with hands off the levers? I just looked up the current Case 590 Super N and it's only rated to lift ~4,100 pounds even with the "Power Lift" or "Power Boost" function which increases power a bit beyond normal. They're known for being pretty strong lifters.

Yea if the boom was near vertical the dipper would lift the blocks to a point a few feet off the ground and if i continued would begin to pull the boom out (overcoming the boom cylinder).

May be time for a seal job then. Mine's also due on both the boom and the dipper. I'd do a leakage test.

Sold your New Holland?

Yep.

Bye Bye old friend. Be good to your new owner.

Sure you're crying a little on the inside but remember, every feller needs a spare.

I have friends wouldn't own anything but Ford New Holland. They've had several 4500, three 555 A, B, C.
They now have a 655A well loved since birth, now offered for sale.
They had a number of articulated wheel loaders, now a compact track loader.
Large excavators Ford & New Holland are pretty scarce, they have several Case.
Dozer track loaders are exclusively IH 175, I thought they had one Dresser 175, my son informs me only the decals are Dresser. After he had sold his brother's 5 or six, I asked Ken how many 175s he still had. "only one" he answered. Later that day I viewed 4, three in daily use.
Ford or New Holland 555 are very common, I've never before seen a 575 with or without a letter.

Congratulations NH! On to different projects! Hopefully, you stick around to converse with the buddies you've made here!

Some of the exposed shelf rock on the top of the ridge( building site) was too much to move ( early on) so it was destined to be incorporated into a planting bed. We started this 2 seasons back 'cause we needed a place to put some perennials we had....in addition to a 'patio' spot to view the western sky ( sunsets!).
This week I got a 'round to-it'.....
