Associated running gear and piler improvements in a two row harvester and piler

Claim 1

A whole stalk, sugar cane harvester for simultaneously cutting adjacent, parallel rows of cane separated by a furrow and selectively piling the cane laterally to said rows either outwardly or inwardly behind the harvester, comprising: (a) a harvester chassis having a pair of front wheels adapted to travel outside said adjacent cane rows and a rear wheel centered between the two front wheels and adapted to travel in the furrow between said rows; (b) means for steering and propelling the harvester along the cane rows; (c) cane gathering and cutting means mounted on the chassis at the front of the machine for gathering and cutting cane simultaneously in said adjacent cane rows and forming the front portion of a cane travel path; (d) a pair of piler arms with outer and inner ends, pivotally mounted at their ends on opposite sides of the chassis behind the gathering and cutting means, forward of the rear wheel and inside the front wheels; (e) a pair of cane travel paths on opposite sides of the rear wheel formed between the cutting and gathering means and the outer ends of the piling arms, the cane travel paths including means for transporting cane along said travel paths; (f) piler arm moving means for selectively moving the outer ends of the piler arms between outboard and inboard positions; (g) the piler arms being shaped and located so that the travel paths are free of sharp angles when the piler arms are in both the inboard and outboard positions; (h) the piler arms being sized and located so that the outer ends of both piler arms project outside the front wheels in the outward position, one piler arm being sufficiently longer than the other one so that the cut cane from both piler arms can be simultaneously piled over said furrow when the piler arms are in the inboard position; and (i) means for simultaneously piling the cut cane from both rows outwardly lateral to the row from which the can is cut when the piler arms are in the outboard position and inwardly lateral to said rows and over said furrow when the piler arms are in the inboard position.
