Patent number: 8042290Abstract: A system and process for controlling and actuating an excavation implement during excavation between an above-ground position and an operator specified below-ground position and for maintaining the specified below-ground position once achieved. The actuation of the excavation implement is regulated by use of an operator modifiable relationship between an engine operating speed and an actuator speed. The actuation of the excavation implement is further regulated by use of an operator modifiable relationship between an attachment drive speed and the actuator speed. A computer network controls the actuation of the excavation implement in response to inputs from the operator and feedback from the engine speed, the attachment drive speed, and an actuator position sensor as the excavation implement progresses through the earth.Type: GrantFiled: July 26, 2010Date of Patent: October 25, 2011Assignee: Vermeer Manufacturing CompanyInventor: Ty Hartwick

Publication number: 20090158624Abstract: The present disclosure provides a trencher control system that is reliable and easy to service. The trencher control system according to the present disclosure includes an improved wiring layout that, in part, results in a trencher that is more reliable and also easier to repair. In one embodiment of the present disclosure, control nodes of the control system are located near the trencher components that they control. The layout of the control nodes significantly reduces the overall wiring, and particularly reduces the amount of wiring extending to and from the cab. A method of controlling a trencher remotely is also provided.Type: ApplicationFiled: December 16, 2008Publication date: June 25, 2009Applicant: Vermeer Manufacturing CompanyInventor: TY HARTWICK
