| 20080271427 | Horizontal rotary cutting system and method - The present invention is directed to a horizontal rotary cutting system and a method for using such system to cut plant material, such as crops and tall grasses. The axis of rotary motion of the cutting blade is essentially horizontal, i.e., or parallel to the ground and is essentially perpendicular to the longitudinal axis stalk of the plant material to be cut. The cutting blade has an elongated cutting surface that rotates perpendicularly toward, and passes through and cuts the plant material stalks. A cutting diameter of about two inches or less is used to achieve lower horsepower requirements, lower friction losses, and lower vibration of the system when compared to prior systems. High speeds of rotation of the cutting blade permit and facilitate the use of high ground speeds of the cutting system. | 11-06-2008 |
