Possibly, but I do not fully understand US English. Please elaborate on what it is, how big a machine will pull it, and the nature of the "brush" ie small, or as in Oz, "bloody great trees". Old McDonald.
i built this rake for our IH TD9 dozer using some thick steel plate to cut the teeth outa and the rest were parts of a forklift mast. took a few nights of welding after all the pieces were cut and tacked together, but it works great
Here is one that I made out of solid rod and well casing for my dozer. Relatively light duty but it shows the principles you are looking for.
That's 7018 from a lincoln tombstone AC 225 stick welder. I realized after this project how important good surface prep is at the ground clamp and at the weld. I also now fab with 6013 for prettier welds and moisture tolerance.
Note the hinge allows the rake to flip up as you backblade. Also the hinge style allows the rake to be picked up without pinning it on.
I modeled the rake after the early D21 like post. Spacing was 10" with 12" of tine length. It worked great until I hooked the outer tines on stumps and then they snapped off. It isn't a stumping rake but a raking rake.
