摘要： Systems and method for linearly displacing an object, such as a cutter or other component, in response to a rotation of a pivotable arm are disclosed. The systems and method encompass one or more actuators, such as hydraulic cylinders, to pivot a pivotable arm pivotable about an axis. A flexible component coupled to an end of the pivotable arm is displaced in response to the rotational motion of the pivotable arm. Movement of the flexible component in response to rotation of the pivotable arm is converted into linear motion via curved surface on which the flexible component rides. The pivotable arm is rotated in response to actuation of one or more actuators, such as one or more hydraulic cylinders, coupled to the pivotable arm.

摘要： A mowing sickle drive system comprises a knife bar supported by a frame and drive apparatus operable to drive the knife bar in a reciprocating linear motion at a variable drive frequency. A spring is coupled to the knife bar for applying a restoring force to the knife bar toward a neutral position when in motion. The spring has a variable modulus of elasticity that is controlled dependent upon the drive frequency.

摘要： In a swather a support arm is attached to the header to carry the heavy hydraulic hoses which are connected to the tractor for supplying the drive fluid to the hydraulic system of the header. The support arm is articulated so as to accommodate the up-and-down and twisting movement of the header relative to the tractor during harvesting action and this supported to prevent collapse when the hoses are disconnected from the tractor manifold. The support arm is attached at the rear to the tractor preferably at the wheel strut by a releasable ball joint coupling. From the coupling at the wheel strut, there is a free portion of the hydraulic hoses which extends to the manifold at the tractor where the ends of the hoses are attached to manually graspable handle portions which can be lifted away and the attached to a bracket on the support arm.

摘要： A sickle cutting system is mounted on a header for forward travel over ground having a standing crop thereon and includes a cutter bar with a plurality of knife guards and two opposed sickle bars driven in opposite phase with a drive system for driving the sickle bar through repeated cycles of reciprocating movement from start-up of the system through to a shut-down. The drive system includes a control device responsive to the sensor signals from both of the first and second drive systems for advancing or retarding one of the first and second drive systems so that a number of sensor signals obtained from the first drive system is continually maintained so as to be substantially equal to a number of sensor signals obtained from the second drive system to maintain the sickle bars in opposite phase.

摘要： A cruise control system for use in connection with a control arm linked to a swash plate that is moveable to provide the swash plate with a plurality of non-discrete angular orientations to affect fluid displacement of a hydraulic pump and a return to neutral mechanism for moving the control arm from a driving position to a position in which the swash plate does not affect fluid displacement of the hydraulic pump. The cruise control system includes a cruise control arm having a portion occupying a plane in common with a portion of the control arm. The cruise control arm is moveable to place the portion of the cruise control arm into contact with the portion of the control arm to prevent the control arm from moving from one of a plurality of non-discrete forward driving positions to the neutral position under the influence of the return to neutral mechanism.

摘要： A boom mower attachment that moves a cutting mechanism in a first movement, a second movement, and a third movement by only using two motions of a single control and method of use thereof is provided. The boom mower may include a frame, a boom assembly carried by the frame, a cutting mechanism operably engaged with the boom assembly, and at least one translation assembly operably engaged with the boom assembly and the cutting mechanism that moves the cutting mechanism in one or more of the first movement, the second movement, and the third movement. An implement control system including a control, at least one function switching mechanism, and an implement is also provided. Activation of the control is operative to move the implement in a first mode, a second mode, and a third mode by only using two motions of the control.
