摘要： A method for calibrating a proportional solenoid valve used in the propulsion system of a windrower, wherein a programmable control module in connection with a valve and a sensor is programmed as part of an automatic calibration routine for directing test control signals to the valve for causing a predetermined displacement of the hydraulic cylinder, the test control signals having values which vary based on the actual displacement of the hydraulic cylinder as compared with a predetermined value of displacement, and operating the hydraulic cylinder using the test control signal that causes the predetermined displacement of the element. The predetermined displacements correspond to the crack points, or the electrical signal levels at which two ports of interest are just beginning to open to one another from a closed position. Of particular interest are the crack points from the supply pressure port to each of the work ports and from the tank port to each of the work ports.

摘要： A method of controlling the operation of a loader to encourage the use of an operator restraint mechanism is disclosed wherein a first signal is generated by a seat sensor to indicate the presence of the operator in the operator seat and a second signal is generated by a sensor in the operator restraint mechanism to indicate use of the mechanism. The hydraulic system will not be enabled unless the second signal is generated immediately subsequent to the generation of the first signal. Unless the first and second signals are generated in the proper sequence, the starting of the engine will also be disabled. The generation of first and second inverse signals, indicating the lack of the presence of the operator in the seat and the disengagement of the operator restraint mechanism, respectively, will disable the loader hydraulic system. A delay is provided to permit the operator to vacate the seat for a short period of time without having to resequence the generation of the first and second signals to enable the loader hydraulic system.

摘要： In one embodiment, an operator control panel includes an enclosure in which a liquid crystal display and a pair of lamps are disposed. A first reflective surface is located inside the enclosure, and a second reflective surface is located outside the enclosure. The lamps are positioned so that light rays from their filaments are projected rearwardly onto the first reflective surface and then forwardly onto the back of the liquid crystal display while other light rays from the lamp filaments are projected forwardly onto the second reflective surface and then downwardly onto the front of the control panel. In another embodiment of the operator control panel, the lamps are disposed outside the enclosure and the second reflective surface is omitted.

摘要： A hydrostatic system and method of operation thereof, wherein at least one of a fluid motor and a pump of the system has a displacement which is variable for controlling a speed of operation of the motor, the pump being driven by an engine, and a controller configured for monitoring the speed of operation of the motor and an operating characteristic of the engine and automatically controlling the displacement responsive thereto, wherein if the operating characteristic is indicative of engine performance above a predetermined threshold, the controller will control the displacement for maintaining the speed of operation of the motor at about a predetermined value, and, if the operating characteristic is indicative of engine performance below the threshold, the controller will hold the displacement at a constant value. As a result, the controller can prevent the system from further decreasing the engine performance. And, if the engine performance increases to that or another threshold, the controller will automatically switch back to controlling the displacement for holding the motor speed at the predetermined value, optionally including to incrementally increase the speed to the predetermined value.

摘要： The device is a multifunctional handle for controlling an agricultural combine. The device consists of palm grip with a finger rest. Attached to the palm grip is a crescent control region. The crescent control region has an upper control area and a lower control area separated by a thumb rest area. The control areas have various controls arranged by usage. The control areas are stepped from the thumb rest area so as to allow the operator to tactilely sense the position of his right thumb relative to the control areas. The palm grip and finger rest are tapered so as to be ergonometrically comfortable for the operator's arm.

摘要： In an automatic draft control system for positioning a hitch, velocity feedback loop techniques are employed to control the rate of movement of the hitch. When the system is operating in an open loop position control mode, a switch mounted on a tractor fender enables an operator to manually control raising/lowering of the hitch for the purpose of attaching an implement. Hitch position is sensed and a microprocessor calculates the first derivative of the hitch position signal to determine actual hitch velocity. The actual velocity is subtracted from a desired velocity value to obtain a velocity error signal. The error signal is subjected to an integral control algorithm and the integrated value is used to energize raise or lower solenoids controlling a valve which raises or lowers the hitch. When the actual hitch velocity is equal to or greater than the desired hitch velocity, the integrated value is saved. When the next raise/lower sequence is initiated the integrator is reset to the saved value. This eliminates delays in starting hitch motion. The desired velocity value may be derived from the setting of a drop rate potentiometer in which case a drop rate value is added to the integrated error signal with the result being used to modify a hitch movement command that energizes the "lower" solenoid, thereby limiting the hitch drop rate when the system is operating in a closed loop position/draft control mode.
摘要翻译： 在用于定位搭接的自动牵伸控制系统中，采用速度反馈回路技术来控制搭接的移动速度。 当系统工作在开环位置控制模式时，安装在拖拉机挡泥板上的开关使得操作者能够手动地控制挂钩的升高/降低以便附接工具。 感测到挂钩位置，微处理器计算挂钩位置信号的一阶导数以确定实际牵引速度。 从所需速度值中减去实际速度，以获得速度误差信号。 误差信号经受积分控制算法，并且积分值用于激励控制升高或降低牵引力的阀的升高或下降螺线管。 当实际牵引速度等于或大于所需牵引速度时，积分值被保存。 当启动下一个升/降序列时，积分器将重置为保存的值。 这消除了启动牵引运动的延迟。 期望的速度值可以从下降速率电位计的设定中导出，在这种情况下，将下降速率值加到积分误差信号上，结果用于修改对“下”螺线管通电的牵引运动指令，从而限制 系统在闭环位置/牵引控制模式下运行时的牵引降速率。

摘要： A loader having an engine operably startable in conjunction with the closing of an associated electrical circuit, hydraulically operated boom and bucket mechanisms controllable from the operator seat, and an interlock mechanism requiring a proper sequencing of seat and seat belt switches to enable operation of the engine and hydraulic system is disclosed wherein the electrical circuit is provided with a service override feature that permits the engine to be started without undergoing the proper sequencing of the seat and seat belt switches. Whenever the contrtoller electrical circuit is placed into the service override mode, the hydraulic system cannot be enabled. The service override switch is interconnected with the normal operation switch so that both switches cannot be closed at the same time.
