I give up. I guess I'll have to download Sketchup and fritter away a day learning how to use it or buy a scanner ... grrrr.

Hope you don't mind, Baby Grand, but I think I know what you're getting at.

Please excuse the crudeness, I'm still learning!

I claim the right to resurrect this thread since I started it in the first place.

I've used this ripper a lot since I built it, but it's never been as sturdy as I'd like. I spent some time in the garage tonight and made the design changes pictured below. I took it out for a test run tonight, and I dropped the three shanks as far as I ever have and didn't get any bending. I think that dropping the lift arm attachment pins lower helped as much as the added steel did. Hopefully I have a final product now.

P.S. This is the first real project I've made since I got my horizontal band saw working. It was very nice to cut the mitered angles on that piece of steel that is reinforcing the front of the ripper.

Congratulations - that looks plenty beefy. Can't wait to see pictures of ripped soil!

Thats a 4 inche square stock, then how wide are the shanks? 3 inches? I'm also curious about why some subsoilers have shear bolts, and others do not. Thanks.

Why some have shear bolts...

3 inches sounds about right for those shanks.

I've used it quite a bit this spring. I've used the new improved ripper in conditions that stopped the tractor, and I didn't bend the implement. That tells me I've finally arrived at a design that's good enough for my needs.
