Abstract
Abstract A three-row forage harvester has a header provided with a stalk gatherer above the dividers thereof which includes a primary gathering unit having a stalk receiving throat and a secondary stalk engaging unit releasably connected to the primary unit within the throat. The yoke of the secondary unit may be height adjusted not only by virtue of the use of extensible yoke supporting arms but by virtue of the invertibility of the entire secondary unit itself.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
65 words
In a stalk gatherer for row crop harvesters: a gathering unit having a forwardly opening, stalk engaging yoke; and a support for said yoke including: a pair of relatively superimposed arms attached to the yoke and extending rearwardly therefrom, and structure at the rearmost ends of the arms for connecting the same with the harvester, the arms diverging as said rearmost ends thereof are approached.
Claim 2
Dependent Claim
65 words
In a stalk gatherer for row crop harvesters: a gathering unit having a forwardly opening, stalk engaging yoke; and a support for said yoke including: a pair of relatively superimposed arms attached to the yoke and extending rearwardly therefrom, and structure at the rearmost ends of the arms for connecting the same with the harvester, the arms diverging as said rearmost ends thereof are approached.
Claim 3
Dependent Claim
28 words
In a stalk gatherer as claimed in claim 1 wherein said arms are of differing lengths and said unit is invertible for varying the height of said yoke.
Claim 4
Dependent Claim
21 words
In a stalk gatherer as claimed in claim 1 wherein said arms are extensible for varying the height of said yoke.
Claim 5
Dependent Claim
18 words
In a stalk gatherer as claimed in claim 1 wherein said arms are in a common vertical plane.
Claim 6
Dependent Claim
42 words
In a stalk gatherer as claimed in claim 1 wherein said yoke is generally U-shaped, presenting a bight and a pair of fingers, one of the arms including a fork extending rearwardly from the bight to which the other arm is attached.
Claim 7
Dependent Claim
86 words
In a stalk gatherer for row crop harvesters: a primary gathering unit having a pair of horizontally spaced horns, presenting a forwardly opening, stalk receiving throat; and a secondary gathering unit having a forwardly opening, stalk engaging yoke within said throat; said secondary unit being provided with a support for the yoke including: a pair of arms within a common vertical plane, attached to the yoke and extending rearwardly therefrom, and structure at the rearmost ends of the arms connecting the same with said primary unit.
Claim 8
Dependent Claim
86 words
In a stalk gatherer for row crop harvesters: a primary gathering unit having a pair of horizontally spaced horns, presenting a forwardly opening, stalk receiving throat; and a secondary gathering unit having a forwardly opening, stalk engaging yoke within said throat; said secondary unit being provided with a support for the yoke including: a pair of arms within a common vertical plane, attached to the yoke and extending rearwardly therefrom, and structure at the rearmost ends of the arms connecting the same with said primary unit.
Claim 9
Dependent Claim
39 words
In a stalk gatherer as claimed in claim 6 wherein said primary unit has a pair of generally U-shaped sections provided with rear, vertically spaced intermediate portions, said structure connecting each arm with a corresponding one of said portions.
Claim 10
Dependent Claim
18 words
In a stalk gatherer as claimed in claim 7 wherein said arms converge as the yoke is approached.
Claim 11
Dependent Claim
43 words
In a stalk gatherer as claimed in claim 8 wherein said structure pivotally connects the arms with said portions, wherein one of the arms is pivotally coupled with the yoke and wherein said arms are extensible for varying the height of the yoke.
Claim 12
Dependent Claim
35 words
In a stalk gatherer as claimed in claim 9 wherein said structure releasably connects the arms with said portions and wherein said secondary unit is invertible for further variance of the height of said yoke.
