Abstract
A baler has a housing normally displaceable in a travel direction along the ground and forming a rotary baling chamber, guides forming relative to the direction a passage having a forwardly opening front end and a rear end opening rearward into the chamber, a pickup device forward of the passage for picking a strand of crop up off the ground and feeding it up and back to the front end of the passage, and a conveyor having relative to a conveyor axis at least two angularly spaced sets of radially projecting and axially spaced arms engageable radially downward into the passage and movable backward in the passage to advance the strand of crop backward in the passage and into the baling chamber where it is wound up into a large cylindrical bale. The arms of each set are axially aligned with one another and angularly offset from the arms of the other set. A rotatable cutter below the passage has a shaft carrying two sets of generally identical and generally semicircular blades engageable up into the passage at the conveyor with the blades of one of the sets being axially interleaved with but offset by about 180.degree. to those of the other set. The cutter and conveyor are synchronously…
