Abstract
A swing-tongue harvester (10) has a hydraulically controlled pulling tongue (30) that can be operated from the tractor seat to change the lateral position of the machine relative to the towing tractor (36), notwithstanding thepresence of a mechanical drive line (90) which extends along the tongue (30) and branches down to a gearbox (116) carried by the header (50) for driving the operating components of the header (50). Telescoping steering linkage (138) between the swing tongue (30) and the gearbox (116) causes the gearbox (116) to swing responsively with the tongue (30) when the tongue is swung to any of its angular positions, thus keeping the input shaft (114) of thegearbox (116) oriented properly toward the driveline (90) along the tongue (30). The connection points for the steering linkage (38) between the tongue (30) and the gearbox (116) are such that a telescoping section (106) of the drive line (90) bridging the tongue (30) and the input shaft (114) of the gearbox (116) has equal angles maintained at its universal joints (104,110) at opposite ends of the telescoping section (106) to reduce unequal loading at those locations. Specifically configured impeller plates (186) associated with the left and right, endmost rotary cutting units (172) on the cutter bed of the header (50) assist in proper delivery of the cut materials rearwardly into the discharge opening (65) of the header (50).
