I know they broke down with one machine for an hour and a half when we were cutting beside them. My mother noticed it, not myself, cause she was running a combine committing how we were out cutting them big time with our ole junk, and probably a fraction of the invested dollar in iron. I did notice they were working on the their headers the next morning. I even stopped and commented that I did not know the bumble bees yellow drapers were Mc Don's now, not HoneyBee's.
