Attachment for digging asparagus crown furrow?

[browndd1]

Hi,
I am new to the forum and was wondering what would be the best attachment for my Ford 3000 tractor to dig a furrow for asparagus crowns?

Thanks

You can arrange the tines on the Japanese tillers to leave a furrow.

I used a potato (middle buster) plow. Worked fine. The soil that's thrown out can be raked back over to cover the new growth.
