What's the COO of the Ripper?

Looks like the ones on my Woods. I suspect, due to the roughness of my castings and overall low fit and finish that they are Chinese. If thats the case, it could be a case of chinese mystery metal.

Here are two more photos of the shank. The rusty bit is likely from my drooping it while trying to remove the upper broken bit from the box blade.

I'm far more concerned about the peening of the scarifier shank pockets. At the fold on the rearward bottom of the shank pocket, the metal becomes thinner, and is likely work-hardened from the bending process, making it weaker than in other areas of the shank pocket.

This photo shows how the paint is chipping off as the metal bends outward.

This is the worst of them and shows a crack has formed and is working upward.

Here we see the lefthand side

For those who believe that I'm beating the crap out of the tool, here is a video of everything I have done with the exception of an easement cut which is on a different video. From my perspective, I thought this was all easy work and of all the times I got snagged, it was on the blade itself which looks like new.

And for those who are wondering, yes, I did get the Christmas Tree over to the Ranch House.

That looks like some very brittle metal on the ripper if it cracked and popped a little chunk out. Probably a low quality casting, or a casting not intended for this kind of stress.

The design of the shank pockets definitely has a weak spot where it's deforming. All the load will focus on that one spot, and has only the plate thickness to support it. I am guessing EA designed it this way to avoid cutting slots into the square tube. But the pocket needs more reinforcement behind the rear plate.

I have a pretty basic Howse box blade. The rippers slip through slots cut into that front square tube. While that probably reduces the stiffness of the square tube a little bit, it provides a bunch more support to the rippers -- there's probably about an inch of plate on edge behind each ripper.

I have only owned two tractors, and both relatively light Kubotas. Both will run out of steam or traction long before they could damage a box blade, especially in snowy/muddy conditions like you show. So I really doubt you're doing anything that could damage the box. I think the ripper was cast poorly, and I think those pockets need more than a plate thickness to support the rippers. Hopefully EA will comment.

Buy once, cry once. Shoulda bought that Gannon.

I think it was a design or manufacturing flaw in the shank personally.

I have used my 7ft box blade like crazy this year, snagging stumps, roots, bricks, boulders, etc. I've never broken a shank.

Today I graded about an acre size parking lot that was paved with asphalt millings. I used the shanks to break up the asphalt, much of it being solid patches. That's pulling in Med gear with 48 HP, up to around 7-8 mph.

I really doubt it was the cold...

How are the shanks held in on your Rhino box blade?

I thought I was buying something comparable to the Gannon/Woods product and far superior to the 84" Howse box blade my Kioti dealer has in stock.

I can't believe how much the stake pockets are deforming. Far as I can tell, my box blade is either a rhino or JD. I got it used, so who knows how many hours it had before I got it, but I've probably put well over 100 hours of use on it this year, probably closer to 150, and it's still in excellent shape. I think there's a metal quality issue going on with that EA box.

Thru the box ... I'll have to see if I have a pic in my phone, it's cold and dark outside right now lol

Sorry, my comment was a bit harsh. I had less deformation of the tubing on my medium duty Bush Hog BB after a couple thousand hours of hard duty and sold it for $600. I bought my Gannon VERY used and I bet it will outlast my tractor. That closeup of the shank is also interesting. It looks to be cheaply made. Kinda surprising coming from EA, but I've never owned anything from them so maybe not.
