摘要： A mower conditioner includes a rotary style cutter bed and a pair of laterally extending crop conditioning rolls spaced rearwardly from the cutter bed. Crop flow is improved in the machine by a laterally extending conveying roller located between the cutter bed and the nip defined by the conditioning rolls. In particular, the conveying outer roller serves to lift cut crop up from the cutter bed and convey the crop rearwardly to the nip. This ensures that the cut crop moves in a steady stream from the cutter bed to the conditioning rolls, and thereby reduces the risk of cut crop being thrown forwardly by the cutters. A downwardly open area is preferably defined between the conveying roller and the cutter bed to provide a space through which dirt and debris can drop out of the machine. The conveying roller preferably has a rotational axis that is lower than the rotational axis of the lower conditioning roll and generally vertically aligned with the substantially planar cutting zone defined by the cutter bed.

摘要： A harvester which uses a rotary style cutter bed has a series of rotary cutters extending across the path of travel of the machine and rotatable about individual upright axes. Part of the cutter bed is a flat gear case containing a train of intermeshed spur gears that serve to distribute power between the cutters above the gear train. Each end of the gear case has a hollow, gearless extension welded thereto which supports at least one additional outboard cutter that receives its driving power exteriorally of the gear case. One embodiment uses a mechanical drive to bring power to the upright shaft of the cutter having the first spur gear so that the cutters with gears receive all their power from the driven cutter. The outboard cutters not having gears are driven by exterior, over-the-top drive mechanism coupled with the shafts of the first and last geared cutters, such drive mechanism alternatively taking the form of timing belts with timing sheaves, chains and sprockets, gear box and universal joint couplings or a spur gear train. As an alternative to a mechanical drive, the cutter bar may utilize a pair of hydraulic motors coupled with the shafts of the first and last cutters having gears. All of the gears in the gear case remain positively enmeshed with one another in the gear train, so that the two hydraulic motors share the total load of driving the cutter bed and such loading is balanced between the two hydraulic motors, prolonging the useful life of the gears and other drive components. The added on, outboard cutters are driven over the top using timing belts, timing sheaves, universal couplings or a spur gear train.

摘要： A crop harvester of the rotary cutter bed type has a series of rotary cutters extending across the path of travel of the machine and rotatable about individual upright axes. The cutter bed extends in opposite directions beyond the ends of a central discharge opening to the conditioner rolls. Cutters located outboard of the opening direct cut crop materials along the front of the cutter bed until the opposite extremities of the discharge openings are reached, whereupon pairs of cooperating, oppositely rotating cutters in front of the opening function to propel the crop material rearwardly with the main flow of cut materials. Alternative forms of conveying means are provided in association with the outboard cutters for moving the cut crop centrally without the use of augers or other additional gathering mechanism behind the row of cutters.

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

摘要： Standing crops severed by sickle mechanism at the leading edge of the machine are swept upwardly and rearwardly along a platform by a rotating reel to a lower, center-gathering auger and an upper, spaced distributing auger that converge the materials centrally and distribute them evenly across a discharge opening ahead of rearwardly positioned conditioning rolls. As severed materials pass through the machine, the flow is gently and progressively converged vertically due to the distances between the reel and the underlying platform, the two augers, and the conditioning rolls becoming progressively smaller. The lower auger serves as the primary central-gatherer, while the upper auger performs primarily as a distributor to spread materials which have been gathered by the lower auger over a substantial width of the discharge opening to the conditioning rolls, hence providing a generally uniformly thick and dense flow to the conditioner rolls instead of one which is congested and bunchy at opposite ends of the rolls.
