摘要： A method and apparatus for controlling positioning of an agricultural implement relative to the ground is disclosed. The method involves receiving first and second position signals representing respective first and second positions of the agricultural implement relative to the ground and providing input to a controller for controlling the positioning of the agricultural implement. The method involves receiving an intermediate position signal representing an intermediate position of the agricultural implement and being associated with an intermediate location between locations respective first and second positions. When the intermediate position signal represents a position that is closer to the ground than a threshold intermediate distance due to a ground inconsistency, the method involves modifying the first and second position signals based on the intermediate position signal to represent positions that are closer to the ground to cause the controller to lift the agricultural implement to clear the ground inconsistency.

摘要： A method, apparatus and system for controlling positioning of an agricultural implement is disclosed. The agricultural implement is mounted on a propulsion unit having a positioning system. A position signal is received from a position sensor representing a position of the agricultural implement relative to the ground, and while a difference between the position and a desired position is greater than a threshold difference, a controller produces and transmits an output signal having a control state that alternates successively between an active time during which the output signal causes the positioning system to move the agricultural implement towards the desired position, and an inactive time during which the output signal causes the positioning system to discontinue movement. The respective times are based on a positioning response time and are operable to permit the agricultural implement to settle in a non-transient position during the inactive time while receiving the position signal.

摘要： An apparatus, which may be a tillage apparatus, may have a flexible frame. The frame may be made from open members. The frame may support ground engagers and may be supported on wheel assemblies. The ground engagers may be connected to a spring trip mechanism. The ground engagers may be mounted to open members of the frame with a clamping style mechanism. The clamp mechanism may include wedge devices. The frame may be lowered and raised relative to wheels of the wheel assemblies with a lift mechanism. One row of ground engagers may be raised or lowered relative to the frame independent of another row of ground engagers. An anti-skid or skew control system may be employed in association with the independent height adjustment of one row of ground engagers. A system may be provided to maintain and control the height of a tow hitch forming part of the apparatus.

摘要： A method for conditioning at least one control signal transmitted by a controller is disclosed. The method involves intercepting the control signal and producing at least one output signal for receipt by the positioning system instead of the control signal in response to the control signal. The output signal represents a plurality of active times during which the positioning system is instructed to move the agricultural implement towards the at least one desired position and a plurality of inactive times during which the positioning system is instructed not to move, each active time being followed by a respective one of the plurality of inactive times. Each of the plurality of inactive times is sufficiently long to permit the agricultural implement to settle into a fixed position due to a positioning response time of the positioning system. Other methods, apparatuses, systems, and computer-readable media are also disclosed.

摘要： An apparatus, which may be a tillage apparatus may have a flexible frame. The frame may be made from transverse and longitudinal open members. The frame may support ground engagers and may be supported on wheel assemblies. The ground engagers may be connected to a spring trip mechanism. The ground engagers may be mounted to open members of the frame with a clamping style mechanism. The clamp mechanism may include wedge devices. The frame may be lowered and raised relative to wheels of the wheel assemblies with a lift mechanism. One row of ground engagers may be raised or lowered relative to the frame independent of another row of ground engagers.

摘要： A crop harvesting header including a pickup reel mounted for rotation about a reel axis includes a plurality of reel bats peripherally disposed and having outwardly extending fingers rotatable about a bat axis. A cam track surrounding the reel axis includes a cam surface and a guide surface. A linkage associated with each reel bat has first and second cam followers that engage the cam surface at first and second contact points displacing the linkage while traversing the cam track, the linkage being coupled to cause rotation of the reel bat about the bat axis for changing an angle of attack of the fingers. A guide follower engages the guide surface at a third contact point between the first and second contact points and is offset to cause the first and second cam followers and the guide follower to maintain contact with the guide surface while traversing the cam track.
