I have rented a few extra acres this year and I need to cultivate my soybeans faster, preferably in 2nd or 3rd gear. I decided to try to build a set of rotary shields for my HM-221 cultivator. I was thinking about using a set of rotary hoe wheels as the shields and bending a piece or round stock into the shape of the axle. I am under the assumption that a set of rotary shields is extremely hard to find. Has anyone built a set of these before? I know spraying is a more efficient alternative to cultivating, but I have a lot of time and not too much money. Any advice would be greatly appreciated.

I forgot to attach the picture in the manual. Here it is.

I have fenders in Louisiana 318-542-0896 .

I forgot to mention that I do have the metal fender style shield that came with the cultivator. I'm thinking that the rotary shields will allow me to move faster while cultivating without throwing large clumps of soil onto the plants while their still young.

If you can find them, get the "tunnel type" shields....adjusted right height they let a little dirt in beside the plant, but stop the clods. I liked them on my HM 438 cultivator "back in those days". I tried the rolling shields too, but felt the tunnel type let me go faster and did a better job. Getting any type of shield adjusted right is critical to how good a job they'll do for you.....and the cultivator teeth shovels next to the rows...I always used half sweep shovels next to the row for beans or corn.....turned a little away when the plants are small and turned toward the row a little when the plants get bigger. I never did use herbicide sprays unless it got so wet I couldn't cultivate. (once in 5 years). Then I had to have the spray job done by a custom operator with a "glider" type sprayer do it for me. Hope this helps you.....nothing looks better than a well cultivated row crop....corn, beans, or whatever.
