ETA Subsoiler

[Sysop]

That main ripper shank should be 3/4"x6", not 1/2" thick.
The shank is A36 steel.

Not the shank at the bottom. That is the part that hit under the ground causing the twisting forces against the main shaft, and it is now offset about 3" from where it should be; but the ripper shank or the mount did not bend. What I am calling the main shaft is the honkin big chunk of plate steel that makes up the main body of the implement. The ripper shank mounts to the bottom of it and the 3-point stuff to the top of it. It has angles ground onto the leading edge of it. It twisted and bent to the left leaving the ripper shank at the bottom offset about 3" from where it should be and not facing forward.

There you go simplifying the problem. Don't you know that 3/4" steel costs serious money? And somebody would surely put enough tractor on a 3/4" plate to bend that just as easily.
No, we need to use our brains not our wallets to solve the problem.

The bar has been raised. We now need to see video of it in action working a soil that needs it, not some fluffy garden. A pretty picture (And that does look very nice) just doesn't tell the whole story.

Is my 4035HST too much tractor for such an implement? It is 40HP, it weighs 4367#, plus the loader (1285#), plus the loaded tires (estimated 400# each). So it is roughly 6482 pounds. While I'm sure that creates an enormous amount of tractive forces, isn't this implement built for such a machine?

I'm willing to use my brains, but I may need some education if I need something bigger. Short of building my own that could rip the back of my tractor off, I've not seen one available any bigger or better than ETA's.

I saw your thread on it, very nice. Want me to test it out? You're not that far away...

Here you go.
travel mode, the bar raised.

Here is the parking stand.

How large is that flatbar you used for the main shaft on yours?

Well I don't want to kick you while your down or at least distracted by your own problems. But apparently 40 HP is enough to bend the ETA subsoiler if the tractor is as well set up as yours.
Can they be made to take the punishment that hard ground gives them? Of course as that is the only place they are needed.
Check this out. About 40 HP per shank.

Thanks for the description. I would love to see a picture when you get a chance.
