CROP HARVESTER PLATFORM HAVING A REVERSIBLE DRIVE FOR THE REEL, CUTTERBAR, CENTER-FEED AUGERS AND CONDITIONER ROLLS

摘要

A self propelled windrower is provided with a platform including a reel whichsweeps crop to be cut over a sickle cutterbar and into the nip of a pair ofcounter-rotating center-feed augers that, in turn, deliver the crop to the nipof a pair ofcounter-rotating conditioner rolls; and these driven components may bereversed to disgorgeslugs of crop. The reversible drive includes a hydraulic pump carried by thetractionunit and coupled to a motor carried by the platform. The hydraulic motor ontheplatform is coupled to power a main gear box which distributes power to thedrivencomponents of the platform. Operation of the pump is electro-hydraulicallycontrolledwith a single switch being operable to effect forward operation of theplatform drivetrain, and with a second switch being designed to be moved and held in placeto effectand maintain the drive train in reverse. Both switches cannot be operated atthe sametime, however the machine can be reversed with the platform lowered, fullyraised, oranywhere in between.
