    • An apparatus and method for calibrating a PTO for driving a cutter of a header of an agricultural windrower, wherein a programmable control module in connection with at least signal operated device in operative control of a variable displacement pump operable for controlling operation of the PTO, is programmed as part of an automatic calibration routine for directing signals to the device having values which will increase over time from a first value toward a second value. At the same time, the control module determines when a first movement of the cutter occurs. If the first movement occurs before the second signal value is reached, information representative of an electrical signal corresponding to the first movement is stored. The routine is then repeated using a higher range of electrical signal values to calibrate where the cutter reaches max speed. In either instance, if the speed condition is not reached with the outputting of the signals within the range, the calibration fails.
    • 一种用于校准用于驱动农业采风机的集管的切割器的PTO的装置和方法,其中与操作控制可操作控制PTO操作的可变排量泵的至少信号操作装置相关的可编程控制模块是 被编程为自动校准程序的一部分,用于将信号引导到具有随时间从第一值向第二值增加的值的设备。 同时,控制模块确定切割器的第一次移动何时发生。 如果第一移动发生在达到第二信号值之前,则存储表示与第一移动相对应的电信号的信息。 然后使用更高范围的电信号值重复该程序,以校准刀具达到最大速度的位置。 在任一情况下,如果在范围内输出信号未达到速度条件,则校准失败。
