Abstract

A method for creating a narrow row head unit which may include a back plate secured to a left gearbox and a right gearbox, and which gearboxes may be positioned adjacent one another. Each gearbox may provide rotational power to a pair of stalk rolls and a drive sprocket for a gathering chain. A right mounting tab may be secured to the back plate and the right gearbox, and a left mounting tab may be secured to the back plate and left gearbox. A right plate and leg may extend outward from the back plate adjacent the right mounting tab and a left plate and leg may extend outward from the back plate adjacent the left mounting tab. A narrow row head unit positioned left-of-center on a header may have the gathering chain positioned substantially over the right plate, and right-of-center substantially over the left plate.

Claims (10)

1. A method of reducing the distance between a first and a second narrow row head unit, said method comprising:

a. positioning said first narrow row head unit adjacent said second narrow row head unit;

b. outfitting said first narrow row head unit with an ear guide, wherein said ear guide is formed with an ear guide channel on an interior portion thereof, wherein said ear guide channel faces a first gathering chain on said first narrow row head unit, and wherein said ear guide channel is sized and shaped to allow a portion of a paddle engaged with said first gathering chain to travel along a length of said ear guide channel; and,

c. allowing a paddle engaged with a second gathering chain on said second narrow row head unit to cooperate with an external surface of said ear guide to urge an ear of corn toward a harvester, wherein said first and second gathering chains rotate in the same direction.

2. The method according to claim 1 wherein said ear guide is further defined as being engaged with a top surface of a frame of said first narrow row head unit.

3. The method according to claim 2 wherein said frame is further defined as a left and right leg and a left and right plate, and wherein said ear guide is further defined as being engaged with said left plate.

4. The method according to claim 2 wherein said frame is further defined as a left and right leg and a left and right plate, and wherein said ear guide is further defined as being engaged with said right plate.

5. The method according to claim 3 wherein said first gathering chain is further defined as being positioned primarily above said right plate.

6. The method according to claim 4 wherein said first gathering chain is further defined as being positioned primarily above said left plate.

7. The method according to claim 3 wherein said ear guide channel is further defined as being configured to allow said distal portion of said paddle engaged with said first gathering chain to be positioned in and travel along a length of said ear guide channel when said paddle is moving in a direction from a rearward portion of said narrow row head unit to a forward portion thereof.
