Patent number: 7681657Abstract: A debris guard is provided for an assembly having a variable length cylinder coupled to a housing. The cylinder has a barrel pivotally coupled to the housing and a rod which extends and retracts with respect to The barrel. The debris guard includes a body of flexible material filling a space between the barrel and the wall of the housing and preventing debris from entering the space. The body compresses as the barrel moves toward the housing wall and expands as the barrel moves away from the housing wall. The body of flexible material is bonded to a surface of the barrel and to the wall of the housing. The flexible material is molded and comprises a closed cell elastomeric material.Type: GrantFiled: December 9, 2004Date of Patent: March 23, 2010Assignee: Deere & CompanyInventors: Kendall Lee Giesmann, Robert Lee Wood, Jr., Dennis Aaron Bowman
