  • Patent number: 6158201
    Abstract: 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 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.

  • Patent number: 4765235
    Abstract: During the process of binding a bale of crop material with binding twine in a crop baler, malfunction of the knotter is checked once upon completion of the binding sequence for one bale, and then a second time after the twine has been prepared by the knotter for formation of the next bale. The monitoring system is particularly appropriate for a double knotting mechanism in which each knotter operates through two complete operating cycles during each actuation thereof, a first cycle to complete a knot associated with the just finished bale, and a second cycle to complete a knot in two separate strands of twine to prepare the same for the next successive bale.

  • Patent number: 4168659
    Abstract: Hydraulic "squeeze cylinders" control the size of the discharge orifice on an extrusion baler and are operated by a control circuit that relieves pressure in the cylinders in response to the buildup of a certain predetermined pressure level in the circuit. Pressurized fluid for the squeeze cylinders is supplied by a single-acting pump cylinder that is connected between the reciprocal plunger head and its push rod in such a way as to deliver a slug of pressurized fluid into the circuit on each compression stroke of the plunger, the pump drawing in a fresh slug from a reservoir during each retraction stroke of the plunger.

  • Patent number: 4148254
    Abstract: Pressurized fluid for the squeeze cylinders of an "extrusion" baler is supplied by a single-acting pump cylinder that is connected between the plunger head and its push rod in such a way as to deliver a slug of pressurized fluid into the circuit on each compression stroke of the plunger, the pump drawing in a fresh slug from a reservoir during each retraction stroke of the plunger. The push rod is connected to the plunger in a cranked relationship so that the radial distance between the end of the push rod and the fulcrum point of the crank comprises one lever arm, such lever arm being many times smaller than the lever arm between the fulcrum point and the point of connection of the crank of the pump cylinder.
