Abstract
An agricultural harvesting machine includes a binding mechanism to secure binding material around a crop package and a delivery device to wrap binding material around a portion of the crop package and provide binding material to the binding mechanism. The delivery device includes a needle connected to a needle frame. The needle frame includes a yoke extending between a first arm and a second arm.
Claims20
An agricultural harvesting machine comprising:
- a binding mechanism configured to secure binding material around crop material formed into a crop package;
- and
- a delivery device configured to wrap binding material around a portion of the crop package and provide binding material to the binding mechanism,
- wherein the delivery device includes:
- a needle connected to a needle frame;
- wherein the needle frame includes a yoke extending along a central longitudinal axis, and a yoke arm extending from the yoke for connecting the yoke to a lift link;
- wherein the yoke includes a central section, an upper bar extending from the central section, and a lower bar extending from the central section;
- and
- wherein the central section has an asymmetrical cross-sectional shape through a reference plane defined by a first axis and a second axis both disposed orthogonal to the central longitudinal axis of the yoke.
