Abstract
A telescoping coulter system for an agricultural machine, operable on ground and having a frame and a moveable structure, includes a coulter arm, having a proximal end with a pivot point, and a distal end bearing a rotatable coulter disk. An extension mechanism connects the frame to the coulter arm, and is configured to translate the coulter arm between a raised transport position not in mechanical conflict with the moveable structure, and a lowered operational position in which the coulter disk can contact the ground and is proximate to the moveable structure.

A telescoping coulter system for an agricultural machine operable on ground, having a frame and a moveable structure, comprising:
- a coulter arm, having a proximal end with a pivot point, and a distal end bearing a rotatable coulter disk, the coulter disk having a raised transport position away from the moveable structure and above the ground, and a lowered operational position in contact with the ground and proximate to the moveable structure;
- and
- an extension mechanism, connecting the frame to the coulter arm, including a translating linkage configured to simultaneously translate and rotate the coulter arm to move the coulter disk between the raised transport position and the lowered operational position.
A potato harvester having a telescoping coulter system, comprising:
- an intake, having a nose wing, the intake being moveable between a lowered operating position adjacent ground, and a raised transport position above the ground;
- a coulter disk, moveable about a virtual pivot point from a lowered operating position, in which the coulter disk is proximate to the nose wing, and a raised transport position in which the coulter disk does not mechanically interfere with the intake or nose wing;
- an extension mechanism;
- and
- a coulter arm, having a proximal end pivotally connected to the extension mechanism, and a distal end, the coulter disk being rotatably attached to the distal end, the extension mechanism configured to simultaneously translate and rotate the coulter arm to move the coulter disk about the virtual pivot point.
A method of making a telescoping coulter system for an agricultural device having a moveable structure, comprising:
- rotatably attaching a coulter disk to a distal end of a coulter arm;
- and
- attaching the coulter arm to an extension mechanism configured to simultaneously translate and rotate the coulter arm between a raised position not in mechanical conflict with the moveable structure, and a lowered operational position in which the coulter disk can contact ground and is proximate to the moveable structure.
