摘要： One embodiment of the present disclosure provides a material reduction machine including a clutch configured and arranged to engage and disengage a material reduction tool with an engine based in response to a control unit. The control unit is configured to decelerate the material reduction tool by maintaining the clutch engaged with the engine during an engine speed reduction period. Another embodiment of the present disclosure also provides a method of decelerating a material reduction tool of a material reduction machine. The method includes the steps of maintaining engagement between the material reduction tool and an engine after the engine enters an engine speed reduction mode, and disengaging the material reduction device from the engine before the engine rpm drops below a predetermined level.

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。

摘要： A stump cutter controller and operator presence system includes one or more capacitive sensors in each of the three control levers that control movement of the cutter wheel. A sensor circuit measures changes in the capacitance of the sensors. The controller automatically disengages a drive clutch and applies a brake to the cutter wheel when the controller senses that an operator has left the operating station—which is assumed when the operator has not touched any one of the three control levers of the operator station for a predetermined time. The controller logic is set to allow the clutch to remain engaged during a delay period, of predetermined duration, to permit the operator to move a hand off of one control lever to another control lever. Also, a grace period, of varying duration based on the speed of the cutter wheel, may be provided during which the clutch is reengaged if an operator returns to the controls.
摘要翻译：残杆切割器控制器和操作员存在系统包括控制切割轮的运动的三个控制杆中的每一个中的一个或多个电容式传感器。传感器电路测量传感器电容的变化。当控制器感测到操作者离开操作台时，控制器自动断开驱动离合器并向制动轮施加制动，当操作者没有接触到操作员站的三个控制杆中的任何一个时，假定预定时间控制器逻辑被设置为允许离合器在预定持续时间的延迟时段内保持接合，以允许操作者将手从一个控制杆移动到另一个控制杆。此外，可以提供基于切割轮的速度的不同持续时间的宽限期，其中如果操作者返回到控制器，离合器被重新接合。
