Abstract

A header for an agricultural harvester including an infeed conveyor having a fore end and an aft end, a center knife drive disposed adjacent to and forwardly of the infeed conveyor, and a knife drive cover covering the center knife drive. The knife drive cover includes a main body substantially covering an entire width of the center knife drive, and a seed saver extending rearwardly from an aft end of the main body. The seed saver is substantially planar, includes a width substantially the same as a width of the infeed conveyor, and defines a plane substantially parallel to a longitudinal axis of the infeed conveyor. The seed saver is integrated with the knife drive cover. As such, the seed saver is secured to the header without need for metal brackets and other associated mounting hardware.

Claims (27)

1 . A header for an agricultural harvester comprising:

an infeed conveyor having a fore end and an aft end;

a center knife drive disposed adjacent to and forwardly of the infeed conveyor; and a knife drive cover covering the center knife drive, the knife drive cover comprising:

a main body substantially covering an entire width of the center knife drive, and

a seed saver extending rearwardly from an aft end of the main body, wherein the seed saver is substantially planar, includes a width substantially coextensive with a width of the infeed conveyor, and defines a plane substantially parallel to the infeed conveyor;

wherein the seed saver comprises a slot that receives a fastener attaching the seed saver to the main body; and

wherein the slot has a longitudinal axis extending substantially transverse to a longitudinal axis of the seed saver.

2 . The header of claim 1 , wherein the seed saver is positioned above and forwardly of a belt of the infeed conveyor.

3 . The header of claim 2 , wherein the seed saver is positioned below the main body.

4 . The header of claim 2 , wherein the seed saver is spaced from the infeed conveyor belt about 3-30 mm.

5 . The header of claim 1 , wherein the infeed conveyor includes lugs and the seed saver is spaced from the lugs about 3-30 mm.

6 . The header of claim 1 , wherein the infeed conveyor includes lugs and the seed saver is spaced from the lugs about 6-15 mm.

7 . The header of claim 1 , wherein the infeed conveyor includes lugs and the seed saver is spaced from the lugs about 10 mm.

8 . The header of claim 1 , wherein the seed saver is integrally formed with the main body.

9 . The header of claim 1 , wherein the seed saver is attached to the main body by fasteners.

10 . The header of claim 9 , wherein the seed saver is positioned below the main body.

11 . The header of claim 1 , wherein the seed saver is adjustable in position relative to the main body.

12 . The header of claim 1 , wherein the seed saver comprises a metal, a composite or a polymer.

13 . The header of claim 1 , wherein the seed saver comprises an elastomeric material.

14 . The header of claim 1 , wherein the seed saver comprises fabric reinforced rubber, SBR rubber or neoprene rubber with fabric insert.

15 . An agricultural harvester comprising a header that comprises:

an infeed conveyor having a fore end and an aft end;

a center knife drive disposed adjacent to and forwardly of the infeed conveyor; and a knife drive cover covering the center knife drive, the knife drive cover comprising:

a main body substantially covering an entire width of the center knife drive, and

a seed saver extending rearwardly from an aft end of the main body, wherein the seed saver is substantially planar, includes a width substantially coextensive with a width of the infeed conveyor, and defines a plane substantially parallel to the infeed conveyor;

wherein the seed saver comprises a slot that receives a fastener attaching the seed saver to the main body; and

wherein the slot has a longitudinal axis extending substantially transverse to a longitudinal axis of the seed saver.
