New Patent Awarded for Unverferth Seed Runner Tender’s Self-Filling Design


Unverferth Manufacturing Co., Inc. announces the issuance of a new U.S. Patent, #8,221,047, for its Seed Runner tender’s unique self-filling design. The dual-compartment Unverferth Seed Runner seed tender not only delivers and unloads bulk or bagged seed to a planter or drill, its innovative design allows the conveyor to rotate 180° for filling itself. The conveyor can also be positioned parallel to the tender for transferring seed from one container to another.

“We’re gratified the U.S. Patent and Trademark Office has recognized this unique Unverferth Manufacturing Co., Inc., contribution to materials-handling technology,” says Steve Unverferth, president. “This is another demonstration of the dedicated commitment of all Unverferth coworkers to the development and manufacture of innovative, quality equipment and in satisfying customer needs. The Seed Runner has resonated with farmers since its introduction in 2007. They previously used forklifts to raise the 50-unit (2,500 lbs.) nylon seed bags 15 or more feet to unload into their seed tenders.  The Seed Runner’s self-filling design eliminates this potential danger in their farming operation while speeding up delivery of seed to their planters.” 

U.S. Patent #8,221,047 adds to Unverferth Manufacturing’s portfolio relating to innovative seed tenders and self-filling technology.  Unverferth Manufacturing was previously awarded U.S. Patent #7,690,499 for its innovative self-sealing edges on the intake for the gentlest seed handling and minimal seed damage and owns U.S. Patent #5,888,044 for an innovative loading/unloading conveyor system. The eye-catching color combination earlier this year was awarded a trademark by the U.S. Patent and Trademark office.  Additional U.S. and foreign patent applications for the self-filling technology are currently pending.
