A very significant improvement was making
a bearing protector on the rollers.
This eliminated wrapping.

I modified a Buffalo Rolling Stalk Chopper to roll down my cover crops. The machine has two rows of rollers, four in front and four in back, with eight 23-inch blades per roller. The turning rollers crimp the cover and push it down. It can be run at 8-10 miles per hour, so it's fast and economical. I added parallel linkage so each roller floats independently. The versatile machine has been used on over 1,000 acres in 8 years.
