TODAY’S PATENT – AUTOMATICALLY RAISED AND LOWERED WINDROW ROLLER

The Automatically raised and lowered windrow roller was invented by Nathan R. Drzal on 28th September 2017 bearing patent number US20170273230A1.

The present invention relates to an agricultural vehicle includes a chassis; a header carried by the chassis and including a cutter mechanism, the header being adjustable in a vertical direction; a swath roller carried by the chassis behind the header; a roller actuator connected to the swath roller and configured to adjust the swath roller in the vertical direction; and a controller coupled to the roller actuator. The controller is configured for: detecting when the header raises in the vertical direction; recording a header raising point where the header raises; determining when the swath roller reaches the header raising point; and signaling the roller actuator to raise the swath roller when the swath roller reaches the header raising point.

Self-propelled windrowers are utilized by farmers to cut crop material as the windrower advances across a field and arrange the cut crop material into windrows, which are deposited onto the field behind the windrower to dry. Typical windrowers have a header at the front which will cut the crop material and are driven by a pair of primary wheels linked to a power source, such as an internal combustion engine, and a pair of caster wheels at the rear of the windrower.
