The following is a mail I sent to Bro-Tek company. I had ordered a custom mount Ripper from them.......
**************************
Happy to say that the ripper came rolling in via postal service about noon.
Just like Christmas, trying to get the package open. Had the unit Switched out and mounted in about 20 minutes.
The unit was very well made and even sported a good coat of paint.
Dug right into things on a strange stump that ran along the ground for a couple feet then up. Need to get into a position to get the other 2 sides. Seems to claw out the smaller roots quite well.
Think it would do a much better job if it was a larger backhoe, as mine doesn't have the grunt power that I thought it did.
Worked on a double stump roots for about an hour. I had scratched out what soil that I could earlier and left the roots more readily available. Try and be darned, I couldn't make much headway with them, Came in and had a coffee - have got to rethink this situation. Might need to take out a generator and a Sawzall with very aggressive teeth and cut through the roots to remove a section.
Overall, the Ripper unit is very well built, and I like the angle Iron feature to help give it a firm back to aid in ripping.
The unit fit like it was store bought, so the dim's that I sent you are correct for you to make that size in the future.
Cool beans! I'm sure you will like it and, hopefully, will be as impressed with it as I am.
