Any idea what this rear plow attachment is used for?

Does any know what this is called and used for? 
The one I have is without the side wing attachment bolted on. Also what are those side wing attachments used for?

Cool what’s the purpose of those side wing pieces that bolt on, do you need them?

Furrower blade, with FURROWER sidewings.

For bigger furrow.

Typically the were mounted on a Troy-Bilt tiller. - it is a Hiller/Furrower attachment.

That looks a lot like the kind that go on a troy built tiller. With the wings off you can control the depth for how deep you want to plant a certain crop. Put the wings on when the plant gets to a desired height to furrow up. I usually put fertilizer in the center of the row and then use the furrow to move the fertilizer on the side of your crop. Good for corn, potatoes,bush beans and many others. You could use it to plow but a little light for hard ground

I have the same set up for my troybilt aka the wheelhorse of tillers

With or without the wings this can also be used to turn potatoes up out of the ground. They are also known as middle busters.
