摘要： A harvesting machine including a frame, a rotor assembly rotatably coupled to the frame configured to move crop material, and a plurality of knives movably attached to the harvesting machine. The rotor assembly includes a plurality of spaced apart rotating blades, wherein one or more of the plurality of knives extends into the spaces between the blades. Each of the plurality of knives includes a knife body and a cutting edge having a plurality of teeth, wherein each of the teeth includes a scallop or valley. Each one of the plurality of valleys extends from the knife body to the leading edge of one of the plurality of teeth, wherein adjacent valleys are located on opposite sides of the knife body. The valleys are lined with a wear resistant material to increase the longevity of the cutting edge and cutting ability.

摘要： A bale holder is actuated to hold a bale in a lift gate of a baler. Lift gate actuators are then actuated to lift the gate, while it is holding the bale. A gate position sensor senses the position of the lift gate, and a force detector detects a force that is used in order to support the gate in the detected position. Bale weight generation logic then generates a bale weight based on the sensed lift gate position and the detected force. A control signal is generated based on the bale weight.

摘要： A drive system for an agricultural work machine having a primary drive system configured to drive a performance system for performing a crop preparation or handling operation including a fluid motor, a fluid pump and a tensioner system. The fluid motor is configured to produce a drive force and to be driven by a flow of fluid moving through the motor. The fluid pump is operatively connected to the fluid motor and is configured to drive the fluid motor. The tensioner system is operatively connected to the fluid motor and to the fluid pump, wherein the direction of fluid flow through the fluid motor adjusts the application of at least one force applied to a belt in the drive system. The fluid motor is configured to adjust the force applied to the belt by regulating a belt tension in proportion to a torque provided by the fluid motor.

摘要： A hydraulic system for operating a rear gate of a baler implement includes a hydraulic cylinder having a housing that defines an interior, and a piston that is moveably disposed within the interior of the housing. The housing includes a first fluid port and a second fluid port, each disposed in fluid communication with a first fluid volume of the hydraulic cylinder. A flow rate control valve is moveable between a first position for directing fluid to or from the first fluid port at a first flow rate, and a second position for directing fluid to or from the second fluid port at a second flow rate. The second flow rate is different than the first flow rate.

摘要： A system, method, and apparatus includes management of a net wrap cycle of a cylindrical bale in a baling chamber of a round baler. The baler includes a crop supply assembly that passes crop material into the baling chamber and a net wrap unit. An electronic controller determines a net wrapping condition of the bale in the baling chamber in response to operation of the crop supply assembly, initiates a net wrap start event to dispense a first portion of a net wrap material from the net wrap unit in response to the net wrapping condition being less than a full bale condition, and disengages a component from the crop supply assembly to stop operation of the crop supply assembly when the bale has satisfied the full bale condition. The net wrapping condition includes a diameter growth rate measurement being greater than a net wrap initiation threshold.
