Mandako Land Roller was developed in Canada for use in raising peas and edible beans, said distributor Stewart Peterson of West Fargo, N.D. Crop harvests were hindered by small rocks in the field and the big roller was developed to push the rocks into the soil. The latest issue for farmers is ridding fields of corn plant residue in preparation to planting soybeans. The huge rollers are used to flatten the soil surface.
