Abstract
An example agricultural header may include a reel section coupled to a wing of an agricultural header. The reel section may include one or more bat tube supports at one or more locations along a length of the reel section, one or more bat tubes coupled the bat tube supports, and one or more linkages. A linkage is operably coupled to one of the bat tubes. A shape of the bat tube at one or more locations therealong is altered by actuation of the linkage in response to movement of the reel section.
Claims17
An agricultural header comprising
- a frame comprising:
- a center section;
- a wing pivotably mounted to the center section, the wing pivotable in response to changing topography of a surface as the agricultural header is moved across the surface;
- a reel rotatably mounted to the frame, the reel comprising:
- a first reel section coupled to the wing such that the first reel section pivots in response to pivoting of the wing, the first reel section comprising:
- a central shaft defining a first axis, the first reel section rotatable about the first axis;
- a first bat tube support extending from the central shaft;
- and
- a bat tube coupled to a distal end of the first bat tube support;
- an inboard mount offset from and adjacent to an end of central shaft;
- and
- a linkage that is actuatable in response to pivoting of the first reel section and configured to alter a position of the bat tube relative to the central shaft at at least one location along a length of the bat tube, the linkage including a first link coupled to the inboard mount.

An agricultural header comprising:
- a frame comprising:
- a center section;
- a wing pivotably mounted to the center section, the wing pivotable in response to changing topography of a surface as the agricultural header is moved across the surface;
- a reel rotatably mounted to the frame, the reel comprising:
- a first reel section coupled to the wing such that the first reel section pivots in response to pivoting of the wing, the first reel section comprising:
- a central shaft defining a first axis, the first reel section rotatable about the first axis;
- a first bat tube support extending from the central shaft;
- and
- a bat tube coupled to a distal end of the first bat tube support;
- a linkage that is actuatable in response to pivoting of the first reel section and configured to alter a position of the bat tube relative to the central shaft at at least one location along a length of the bat tube,
- wherein at least a portion the first bat tube support is configured to be displaced relative to the central shaft in response to actuation of the linkage, and
- wherein the central shaft comprises a flange, wherein the first bat tube support is slideably coupled to the flange, and wherein displacement of the first bat tube support relative to the central shaft in response to actuation of the linkage comprises a sliding of the first bat tube support relative to the flange to displace the first bat tube support relative to the central shaft.

A method of altering a position of a bat tube of a reel of an agricultural implement relative to a central shaft of the reel, the method comprising:
- pivoting a first header portion of an agricultural header relative to a second header portion, the agricultural header comprising:
- the first header portion;
- the second header portion pivotably connected relative to the first header portion;
- a reel comprising a first reel section connected to the second header portion such that pivoting of the second header portion relative to the first header portion causes pivoting of the first reel section, the first reel section comprising:
- a central shaft defining a first axis, the first reel section rotatable about the first axis;
- a bat tube support arm extending from the central shaft;
- and
- a bat tube coupled to a distal end of the bat tube support;
- and
- a linkage comprising a link that extends along at least a portion of a length of the central shaft and is coupled to the bat tube;
- displacing the link of the linkage in response to pivoting of the first header portion;
- and
- displacing the bat tube relative to the central shaft in response to displacement of the link.
