I used to design high residue cultivators. They would pop out the weeds, not disturb the residue, loosen the soil, and you could do this at 8-9 mph.

I think Hiniker might be the only one still making that type of cultivator. - http://www.hiniker.com/ag_products%20new/6000_cultivator.html

I will warn you that it takes a real tractor to run that type of cultivator. You are not going to do it with a 3020 JD. It will take something with at least 180 HP to pull a 12 row cultivator.

I remember seeing a piece of literature from Deere that said cultivating increases yields 10-15 bu/acre, even if you don't have a weed problem. Seems like increasing your income $50+/acre would be worth it, but most farmers now would rather go boating in the summer rather than tend their crops.

Here is more information from Iowa State:
