Appl. No.:

7/203778

Inventors:

E. Cordell Lundahl - Providence UT
Laurel H. Jensen - Hyrum UT

Assignee:

Lundahl Research, Inc. - Logan UT

International Classification:

A01D 7528

US Classification:

56 102

Abstract:

A threshing unit including a header having a stripping unit for stripping the grain from the stalks as the unit moves in the field. The threshing unit has height control to accurately position the stripping units at the heights of the heads of grain on the stalk. The grain head is positioned by air flow (for stripping) and the grains is carried into a cleaning unit and then into a combination re-thresher cleaner unit by air flow and centrifugal force. The cleaning is done by air flow and the transport of the grain to an attached or mobile container is accomplished by air flow.

Assignee:

Lundahl Research, Inc. - Logan UT

International Classification:

A01D 3444

US Classification:

56156

Abstract:

Impact cutter teeth that cut and lift the crop to improve both cutting and transport of the crop are novel features of this invention. The novel construction of this tooth results in actions which reduce undesired recut characteristics present in impact cutters with prior art teeth.

International Classification:

A01D 3453

US Classification:

56 144

Abstract:

An auger cutter, windrower and conditioner for standing and downed crops such as hay, or forage harvester crops such as corn, sorghum and cereals including a cutter auger with cutting teeth attached to an auger flight and a conveyor auger to move the cut crop to a central area or to either side of the cutter to be discharged as a windrow or as a mass of material, or to be fed to a second crop processing device such as a forage harvester. An improved relationship of the cutting augers and the conveyor augers and height control mechanism to improve the cutting and transport of the crop.
