Cuts Some, Crimps Some. It's basically made to chop up corn stalks in the fall and does it on the scale between a disc and a flail mower, Groff says. I have adapted this with parallel linkage to roll down the cover crop so I can kink it up and cut some of it. For 1998, Groff made collars to place around the bearings of the rollers.
Parallel linkage is necessary for providing flexibility to deal with stones in some fields.
Then I would have to spray my normal Roundup herbicide rate where even half of the cover crop was killed pretty good. It really doesn't work the cover crop into the soil, but it lays it over and cuts some and kinks the rest. Mechanical Kill . Groff likes the rolling stalk chopper because he doesn't need to use contact herbicides to kill the cover crop. A flail mower he originally used allowed him to get away from contact herbicides, too, but it was slow and took a lot of power, the no-tiller says.
