摘要： An improved brush cutter having an upper feed control member with stop, forward, neutral, and reverse positions also has a lower feed stop member with selectable sensitivity. Another aspect of the invention is to predict the feed roller shutoff point according to the rate of engine deceleration. According to another aspect, when the feed rollers stop feeding material into the cutters, to overcome drag on the cutters, a controller stops the feed rollers and then reverses them for a short time, and then reverses the rollers again if the problem is still present. To prevent jamming, a pressure switch senses when oil in a hydraulic motor system for rotating the feed rollers is too high and the controller momentarily reverses the feed rollers and then causes them to go forward, a cycle which can occur several times until the feed rollers are no longer stalled. By another aspect of the invention, the controller senses characteristics of the brush cutter and chooses an operating system based on the characteristics sensed. The controller can also sense if the brush chipper has not been used for a predetermined period of time and automatically reduce the idle speed of the engine until the brush chipper is used again, and then automatically return the engine to a normal idle speed before the feed rollers will pull brush into the brush chipper.

摘要翻译： 具有具有停止，前进，中立和反向位置的上部进给控制构件的改进的刷子切割器还具有可选择灵敏度的下部进给停止构件。 本发明的另一方面是根据发动机减速率来预测进料辊切断点。 根据另一方面，当进给辊停止向刀具供料时，为了克服刀具上的阻力，控制器停止进给辊，然后将其反转很短时间，然后如果问题仍然存在则再次反转辊 。 为了防止卡住，压力开关感应用于旋转进给辊的液压马达系统中的油太高，并且控制器暂时反转进给辊，然后使其向前运动，这可能发生几次，直到进给辊 不再停滞。 根据本发明的另一方面，控制器感测刷切割器的特性，并且基于所感测的特性来选择操作系统。 控制器还可以感测到刷屑器是否在预定时间段内没有被使用，并且自动降低发动机的怠速直到再次使用刷屑器，然后在进给之前自动将发动机返回到正常怠速 滚筒将刷子刷入刷子。
