Abstract
A mowing finger arrangement and mowing bar for finger bar mowers of a harvester, as well as a method for manufacturing mowing fingers has an upper and lower element connected together to form at least one mowing finger. The mowing finger arrangement serves to guide a mowing sickle and forms counter cutting edges for the sickle blades arranged on the mowing sickle. An abutment on the upper element delimits upward movement of the mowing sickle when a downward force is exerted on the face end of the sickle blades.
Claims14
A mowing finger arrangement comprising:
- an upper element and a lower element, the upper element having an elongated finger portion with an outer surface and an inner surface facing the lower element, the upper and lower elements are connected to form at least one mowing finger, a blade gap to guide a mowing sickle is formed between the lower element and the upper element;
- and
- a projection is formed by an impression in the outer surface of the upper element elongated finger portion so that pushed away material from the finger portion outer surface impression escapes inward to the inner surface to form the projection that extends from the inner surface of the upper element elongated finger portion towards the lower element, the projection includes an abutment for contacting a rear portion of the mowing sickle, when viewed in a working direction.
A method for producing a mowing finger comprising the steps of:
- embossing an upper element with the upper element having an elongated finger portion with an outer surface and an inner surface facing a lower element;
- forming an impression on the outer surface;
- forming a projection under the impression by deforming the upper element elongated finger portion outer surface so that pushed away material from the finger portion outer surface impression escapes inward to the inner surface to form the projection that extends from the inner surface in a direction towards the lower element;
- forming an abutment for contacting a rear portion of a mowing sickle, when viewed in a working direction;
- and
- connecting the upper element to the lower element.

- and
- a projection is formed by an impression in the outer surface of the upper element elongated finger portion that extends from the upper surface between side edges of the upper element elongated finger portion, and so that pushed away material from the finger portion outer surface impression escapes inward to the inner surface to form the projection that extends from the inner surface of the upper element elongated finger portion, between the side edges of the upper element elongated finger portion, towards the lower element, the projection includes an abutment for contacting a rear portion of the mowing sickle, when viewed in a working direction.
