摘要： Netting in the form of an extruded plastic mesh is provided for wrapping round bales of crop material. The netting includes longitudinal strands and tranverse strands fused together at intersecting joints to define rectangularly shaped openings in the netting. The minimum elasticity of the netting is about 15% before tensile failure in a longitudinal direction in order to prevent the netting from shrinking in a transverse direction. The netting thus maintains its original width dimension when pulled lengthwise.

摘要： A blower for conveying material includes a housing and a spout. The housing has a front wall, a rear wall and an arcuate side wall extending between the front and rear walls. A plurality of arms with paddles mounted thereon are rotatable within the housing to discharge material through the spout. Springs are provided to urge a portion of the housing side wall into a normal position while permitting this side wall portion to be flexed outwardly if a foreign object such as a rock impacts against the inside of the housing side wall with enough force to overcome the springs. Permanent deformation to the housing is thus prevented by the springs.

摘要： A mobile harvester unit provided with a row crop attachment having a plurality of laterally spaced generally fore-and-aft dividers defining one or more elongated passageways for accommodating rows of crop material. Crop severing means are disposed along each passageway for cutting crop being guided rearwardly during operation. Feeder assemblies, disposed in longitudinal alignment with the dividers, comprise gathering fingers extending from at least three rigid bars adjacent the passageways. The bars, mounted at equal intervals on rigid rotatable elements, are rotatably driven to impart intermittent rearward motion of the fingers in the passageway to urge crop toward the harvesting unit.

摘要： A disc cutterbar for use on a harvesting implement, such as a disc mower-conditioner, is driven by an endless timing belt entrained around toothed sprockets corresponding to each disc cutter within the transmission casing. The positive engagement between the toothed timing belt and the corresponding toothed sprocket provides a means for timing the rotation of adjacent disc cutters to minimize the possibility of interference between rotating knives. The toothed timing belt, however, is capable of movement relative to the toothed sprocket should the corresponding disc cutter become restricted in its rotation, such as by impact with a substantial object. To provide overlapping paths of travel of knives on adjacent disc cutters, yet prevent interference therebetween, alternating disc cutters are obliquely mounted on the transmission casing so that the path of travel of the knife thereon is within a plane space vertically within the overlap area relative to the path of rotation of the knives on the adjacent disc cutters. A spring-loaded guide urges the timing belt into engagement with the toothed sprocket under conditions where the timing belt is attempting to move away from the toothed sprocket.

摘要： A method used to wrap roll bales of crop material with plastic film. The method involves holding the end of a supply roll of plastic film between stationary feed rolls as a bale is formed, and then delivering the end of the plastic film to the outer surface of a completed roll bale by driving the feed rolls. The method also involves wrapping the roll bale with a suitable number of layers of the plastic film by driving the feed rolls while rotating the roll bale, and then severing the plastic film at a location between the roll bale and the feed rolls by stopping the feed rolls and moving a cutoff bar into contact with the plastic film while continuing to rotate the roll bale.
