Abstract
A windrower (1) useful for collecting stalk material from a field (43) and depositing the material In a windrow (61). The collection of dust and debris in the windrow is minimized by the use of a screen (24) located above the auger (29) which transports the cut stalk material to a discharge chute (14). The screen (24) permits lighter airborne particles to escape from the region surrounding the auger (29) before they are entrained and deposited into the windrow. A screen (47) is also placed beneath the auger (29) to permit small, dense particles to fall from the region surrounding the auger and be deposited on the ground (43). A flexible barrier (48) is placed between the auger and the cutting assembly (32) so that material falling through the screen is not reintroduced to the cutting blades (39, 42). A second barrier (64) is positioned behind the auger so as to form a volume (66) within which material is confined so that it will not become airborne. The windrower wheels (3-10) are adjustably spaced and arranged in pairs so that the number of individual wheels riding on a peak contour (56) within the field (43) is maximized.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
