Filed:

Jul 12, 2010
Appl. No.:

13/383653
Inventors:

Mark Cooper - Pella IA, US
Derrick Deschamp - Indianapolis IN, US
Jeff Flahive - Pella IA, US
Dan Hawks - Pella IA, US
Glenn Meinders - Pella IA, US
Michael Vander Hart - Pella IA, US
Assignee:

Vermeer Manufacturing Company - Pella IA
International Classification:

E02F 3/14
US Classification:

37465
Abstract:

An excavation component is disclosed herein. The excavation component includes a cutter structure carrier and a cutter structure carried by the cutter structure carrier. The excavation component also includes a fastener for securing the cutter structure to the cutter structure carrier. The cutter structure carrier and the cutter structure have an interlocking geometry for transferring shear between the cutter structure carrier and the cutter structure so as to reduce an amount of shear applied to the fastener during excavation operations.
