Patent number: 7942210Abstract: In lieu of rigid bars, a tillage reel utilizes a number of elongated flexible elements such as lengths of link chain that are spaced circumferentially around the reel and extend axially thereof. The flexible elements bow outwardly by centrifugal force as the reel rolls along the ground during tillage operations to impact and fracture clods encountered at the lower front extremity of the reel. When the reel is used in connection with strip till operations, the flexible elements bow upwardly and inwardly along the lower periphery of the reel as they engage and conform to the transverse cross-section of the strip till berm, thereby avoiding destruction of the berm notwithstanding the clod-pulverizing action provided by the flexible elements.Type: GrantFiled: September 30, 2010Date of Patent: May 17, 2011Assignee: Krause CorporationInventor: Thomas W.
