Depending on the size of the blades (I’m guessing they are about 2” or so wide across the face.), it’s a #6 Spring Tooth Cultivator.

That one looks to be part of a set that was mounted to a crossbar that then attached to the drawbar (or possibly a belly rack) of the tractor. (I’d have to see the other side of the apex to be sure.)

You may wish to slap it on eBay as: “Old tractor implement - cultivator” before you destroy it. You might surprise yourself with what some of that stuff goes for to collectors looking for just the right implement.
I have a ’47 Farmall Cub that I purchased a few implements for. None were found cheap.

Just a thought.
