摘要： In a crop conditioner having a frame and first and second rolls each rotatable about an axis of rotation, a mounting assembly for the first roll includes a sub-assembly at each end of the first roll which permit the first roll to be pivoted relative to the second roll. Each sub-assembly has a mounting plate rotatably supporting one end of the first roll and supported on the frame for pivotal movement about a pivot axis which is generally parallel to and displaced from the axis of rotation of the first roll such that the axis of rotation of the first roll is movable relative to the axis of rotation of the second roll between a first position, a second position and a third position. The second and third positions of the first roll are progressively farther away from the axis of rotation of the second roll than the first position. A biasing force is exerted on the mounting plate and the first roll which acts in a direction generally toward the second roll, the biasing force has a magnitude which is less when the first roll is located between the second and third positions than when the first roll is located between the first and second positions.

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 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 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： As crop materials are severed from the field, they pass through two successive pairs of counter-rotating conditioning rolls before being returned to the ground. The front rolls are preferably ribbed, metal rolls wherein the ribs of one roll are intermeshed with those of the other roll so as to crimp the stems of the crop materials as they pass between the rolls. The hard metal ribs also aggressively feed the materials rearwardly into the second set of rolls, which are preferably compressive surface rolls made of rubber or the like and provided with wide, intermeshed bars about their periphery. The tension mechanism for the rolls includes single-acting hydraulic cylinders that squeeze the rolls together to the extent permitted by adjustable stop structure used to set gaps between the rolls. An accumulator is hydraulically connected to the hydraulic cylinders for cushioning the tension mechanism.

The tension mechanism for the rolls includes single-acting hydraulic cylinders that squeeze the rolls together to the extent permitted by adjustable stop structure used to set gaps between the rolls. In typical operations, the gap between the rear rolls is set to be considerably smaller than the gap between the front rolls. Great flexibility in the degree of conditioning experienced by the crop materials is achieved by the nature of the rolls and the ease with which roll pressure and spacing can be adjusted.

摘要： A hold down for retention of reciprocable sickles of cutter assemblies is characterized by its inflexibility and provision of adjustability in relation to the cutter bar such as to preclude undue movement of the sickle sections away from their normal scissors-like cutting positions in cooperation with the sickle guards on the cutter bar. A strong, massive hold down body permits minimum running clearance of the sickle beneath wear pads on forwardly extending fingers integral with the body. After adjustment of a extensible bolt and nut assembly between the hold down and the cutter bar and clamping of the hold down to the cutter bar, essentially trouble-free use can be expected without undue clogging or failure to easily cut even the toughest of grasses, weeds, and crops generally.
