The clevis is a secondary "breakaway" component. If you're plowing on smooth asphalt or gravel where the chances of catching the edge are minimal, it would be optional. If you often have ice or cracks in a concrete driveway, then probably a good idea.

That cab looks like a perfect fit.

It was a custom build by Rick Prentice. Buried in the forum archives he put up a post showing the build. Photos may be lost.

Got my block made and got the plow fitted to the tractor. However i cant get the linkage that attaches to the plow piece that has the big spring on it into the lowest hole, as the linkage hits the front axle.

The bolster blocks look good! What material did you use?

I used 12L14 steel, I have a few chucks i got from a buddy a few years ago. I would have rather made them out of stainless but they will work. I'm sure it will last a very long time.

If I decided to front mount my plow (probably not) I had thought I’d make a pair from Delrin. I’ve made a lot of things out of that stuff. Yours will last forever.

Yea Derlin is pretty tough stuff, I would think it would do the job pretty well.

I finally got the boomerang done, I had some plate laying around. It was a little pitted and was a little undersized from the drawing Don posted so I had to make the blocks thicker to compensate. Assetically I wished it looked better but I made it for free and it will do the job. Works like a charm, there was one discrepancy on the drawing that I found. The hole for the pin that was on the rocker arm was bigger than the print stated, mine was 3/4" so i had to make the hole 3/4". I don't know if all Cubs are like that or if it was just mine.
