Abstract
Abstract A high ground clearance tractor during one pass through rows of a standing crop, such as corn, opens a small furrow for a second crop, such as beans, plants the second crop, sprays suitable chemicals on the new crop, and trims the tops of the existing or standing crop. A large energy savings is realized compared to using separate machines for the required operations. The machine is particularly useful in regions having a long growing season. Two rows of a second crop can be planted between each adjacent pair of rows of the existing crop.
