Subsoiler for Yanking Rocks?

[Suburban Plowboy]

This bolt has a shaft about 0.470" in diameter. Don't know the thread major diameter.

I don't think it matters. It's so close to 7/16", I'm not worried about it.

I see I said 7/8" in my earlier post. Brain flatulence at work. I meant 7/16".

Sure looks like you're having fun pulling rocks. 7/16" is a pretty small shear bolt. I would use whatever shear bolt fits the tightest. Sometimes, a very slightly looser fit will shear easier than the correct size.

It could very well be metric and the maker of the unit will have that info. Dealers tend to guess while the maker knows for sure. Shear bolts are worth getting the right ones.

I have a big 'ol single bottom Pittsburg moldboard plow. I can strip everything off and just have a VERY heavy shank remaining. If its down there the Pittsburg will find it. I use the moldboard shank if I want to go 12" to 14" deep. Otherwise I can use the shanks on either my Bush Hog ROBB or Land Pride LPGS - if I want to scarify shallow.

Experience has shown me - no need to scarify - there are plenty of rocks, right on the surface. I don't need to be dredging more up.

12mm = .472" so I would say it is a 12mm and the thread pitch could be 1, 1.25, 1.5, 1.75mm

7/16 = .437"

I completely forgot that a manual came with this thing. The bolt is M12 x 85mm.

Sub-soilers will pull up rocks. And roots. And buried wires and pipes.

I was using a subsoiler to trench for an invisible fence. Things were going swimmingly. After laying wire and working my way around, I looked back and saw that I had somehow pulled about about 75 yards of the wire I had just laid.

Find out the grade and get a few more with nuts and washers. I write what they are for on the side of the bolt with a Sharpie marker since shear bolts are hard to find when you need them.

One of the best lines I ever heard on the TBN was calling a single shank ripper by its proper name:

Utility Line Locator, Non-Discriminating

That's exactly what it is and better be 100% sure where everything is underground. Old timers liked to run electric to outbuildings by going just a few inches underground.

^^^Yeah, no kidding!

That doesnt narrow things down much. Backhoes fit that bill just as well. Box blades to a lesser degree.
