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 crop baling machine of the type for producing round bales and in which a cylindrical bale forming compartment receives crop material from a pickup device, the bale-forming compartment being defined by an endless apron which extends around inner and outer sets of guide rollers. The endless apron also extends respectively around drive sprockets and takeup guide sprockets which are spaced apart to provide an inlet to the bale forming compartment, the takeup guide sprockets being mounted for limited movement against springs to maintain the apron taut but also permit limited expansion of the inner portion of the apron which extends around the inner set of guide rollers when the bale forming compartment is filled to a desired degree, and the movement of the takeup guide sprockets causing additional mechanism to disconnect the pickup device from the power source which drives it and thereby automatically prevent structural damage to the machine.

摘要： A leaf loading machine has a rotary beater and a rotary broom extending transversely of a mobile frame. The broom is disposed rearwardly of and in tandem relation to the beater. The beater and the broom have lower sides thereof disposed adjacent the ground and they are operable to counterrotate relative to one another so as to deliver material from the ground upwardly therebetween. A shroud mounted on the frame fully covers an upper side of the beater and partially covers an upper side of the broom. The shroud is open at its front and rear ends, and includes a top wall and a pair of side walls. A housing is also mounted on the frame overlying and enclosing the broom and an auger disposed rearwardly of the broom. The housing is closed at its rear end but is open at its front end where it communicates with the rear end of the shroud to guide material delivered between the beater and the broom to the auger. The housing includes a top wall, a pair of side walls, and a rear wall.

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 leaf loading machine has a rotary beater and a rotary broom on a mobile frame, both of which extend transversely of the frame. The broom is disposed rearwardly of and in tandem relation to the beater. Both the beater and the broom are disposed adjacent to the ground and are operable to counterrotate relative to one another so as to deliver leaves from the ground upwardly therebetween. The broom rotates substantially faster than the beater.
