ETA Subsoiler

[vtsnowedin]

Dose anybody make a top link that is spring loaded so that a middle buster or even a bottom plow would become at least a partial trip implement? It might work faster then draft control and save a lot of damaged parts on both tractor and tool.

 

[Sysop]

Not sure, but Ted isn't going to like me very much at all if I keep breaking it every time I use it...

 

[vtsnowedin]

Well maybe ETA and I can come up with a new product that would be a big seller. In just the last fifteen minutes I've gone through three possible designs that might work. Hardest problem would be determining how strong a spring would be required to keep the tool working in good soil but then close up when a solid object was hit before anything is stressed to the breaking point. Might employ some strain gauges to figure it out.

 

[Sysop]

I guess put me on the beta-testers program... :thumbsup:

If it can break, my ground and tractor can apparently do it. :laughing:

Wow.. So at 52 seconds in... Is that where you think it got bent?
Pics please... Inquiring minds want to see the carnage.

Yep, there or the subsequent tug 10 seconds later that also hung, or a combination of the two. Whatever it hit under the ground wasn't square (although rocks seldom are) and it twisted the tip about 3" from center, all the bend is in the main 1/2" plate...

I'll grab pics tomorrow when I've got daylight. It frustrated me (to say the least) that it worked really well till I went for the camera. The camera (my phone) almost went flying when I got ready to start the next row and saw things out of whack; but I contained myself, so at least we have video...

I'd look at this as an opportunity to add a new tool to your shop, if you don't already have one: 20 ton H-Frame Industrial Heavy Duty Floor Shop Press

OK I design them . ETA builds them and, You test them. What could go wrong?

It would be a nice addition once my new building is in. I don't think I'd ever get this plate straight enough to use though. Most of the bend occurred just below the 3 point bracket and created a pretty decent crease, which is sorta weird cause that's the most meaty part of the plate. It was enough of a crease to pop the paint loose.

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

The original design, which has been around for a very long time, was designed so that the ripper could be flipped if worn.

BTW, the subsoiler sold at TSC has a 3/4"x4" ripper. I stopped and measured it the other day.

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.

Here is the one I just finished.

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.

 

[Sysop]

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.
