re: #9 Quoth the raven, Covfefe.

This guy gets it.

An aside, I actually saw one in use (hence the reason it came to mind…) I didn’t think it warranted the size of tractor it was hitched to, until I watched the operator drop it in all the way to the frame. Then it registered.

Our ‘big’ tractor wasn’t all that big, so our subsoiler only had 5 ‘teeth’. You could plant ‘em and stand the tractor on its hind feet!
