Abstract

An agricultural processing system including a chassis with a header coupled to the chassis. The header provides for the ingathering of agricultural product into the processing system. The header including a reel system having a plurality of arms rotationally coupled to the header. The plurality of arms include a first arm and a second arm. There is a cam track coupled to the header. The first link is pivotally coupled to the first arm and a roller is rotatably coupled to the first link, with the roller rollingly following the cam track. A tine bar is pivotally coupled to the second arm. The second link is pivotally coupled to both the first link and to the tine bar.

First claim

What is claimed is:

1 . An agricultural processing system, comprising:
a chassis; a header coupled to said chassis, said header providing for the ingathering of crop material into the processing system, said header including a reel system having:
a plurality of arms rotationally coupled to said header, said plurality of arms including a first arm and a second arm;
a cam track coupled to said header;
a first link pivotally coupled to said first arm;
a roller rotatably coupled to said first link, said roller rollingly following said cam track;
a tine bar pivotally coupled to said second arm; and
a second link pivotally coupled to said first link and to said tine bar.

2 . The agricultural processing system of claim 1 , wherein said second arm follows said first arm relative to a direction of rotation of the reel system.

3 . The agricultural processing system of claim 2 , further comprising a mounting bar connected to said tine bar, said pivotal coupling of said tine bar with said second link being carried out by way of said mounting bar.

4 . The agricultural processing system of claim 1 , wherein a front portion of said cam track does not extend forward of said tine bar in a forward direction of the processing system.

5 . The agricultural processing system of claim 1 , wherein each of said plurality of arms rotates about a central axis.

6 . The agricultural processing system of claim 5 , wherein each of said plurality of arms has a tine bar pivotally coupled thereto, each of said tine bars pivotally coupling to a respective arm equidistant from said central axis.

7 . The agricultural processing system of claim 5 , wherein said cam track defines a plurality of cam distances relative to said central axis.

8 . The agricultural processing system of claim 7 , wherein said cam track includes a front portion and a rear portion, wherein said rear portion defines at least one cam distance which is greater than any cam distances defined by said front portion.

9 . An agricultural processing system, comprising:
a chassis; a header coupled to said chassis, said header providing for the ingathering of crop material into the processing system, said header including a reel system having:
a plurality of arms rotationally coupled to said header and configured to rotate about a central axis;
a cam track coupled to said header, said cam track defining a plurality of cam distances relative to said central axis, said cam track having a front portion and a rear portion, said rear portion defining at least one cam distance greater than any cam distances of said front portion;
a tine bar pivotally coupled to at least one of said plurality of arms; and
a roller coupled to said tine bar, said roller rollingly following said cam track.

10 . The agricultural processing system according to claim 9 , wherein said plurality of arms includes a first arm and a second arm pivotally coupled to said tine bar, said reel system further comprising a first link pivotally coupled to said first arm and a second link pivotally coupled to said first link and to said tine bar.

11 . The agricultural processing system according to claim 9 , wherein each of said plurality of arms has a tine bar pivotally coupled thereto.

12 . The agricultural processing system according to claim 11 , wherein each tine bar carries at least one tine.

13 . The agricultural processing system according to claim 9 , further comprising a cutter bar carried by said chassis, wherein said central axis is located in front of said cutter bar.

14 . The agricultural processing system according to claim 13 , wherein said rear portion of said cam track defines a maximum cam distance to said central axis at a point which is behind said cutter bar.

15 . The agricultural processing system according to claim 9 , wherein said cam track is asymmetrically arranged about said central axis.

16 . The agricultural processing system of claim 9 , wherein said front portion of said cam track does not extend forward of said tine bar in a forward direction of the processing system.
