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： 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 metho 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.
摘要翻译：本公开的一个实施例提供了一种材料还原机，其包括被配置和布置成基于响应于控制单元与发动机接合和分离材料减少工具的离合器。控制单元构造成在发动机减速期间通过保持与发动机接合的离合器来减速材料减少工具。本公开的另一个实施例还提供了一种使材料还原机的材料减少工具减速的方法。该方法包括在发动机进入发动机减速模式之后保持材料减少工具和发动机之间的接合的步骤，以及在发动机转速下降到预定水平之前将材料减少装置与发动机分离。

摘要： The present disclosure provides a device and method that enable the efficient reduction of stumps. In one embodiment the stump removal methods and devices according to the present disclosure allow the operator to have a clear view of the work area during operation, and the ability to move the reduction device through a wide range of motion during operation. In one embodiment, the material reduction tool pivots relative to the chassis in the vertical plane about multiple pivot points. In some embodiments the device includes a retractable auxiliary control panel located at the end of the device opposite the material reduction tool. The control panel enables the operator to direct the movement of the device from the end of the device and thereby enable the device to maneuver through narrow spaces.
摘要翻译：本公开提供了一种能够有效地减少树桩的装置和方法。在一个实施例中，根据本公开的残桩移除方法和装置允许操作者在操作期间具有工作区域的清晰视图，以及在操作期间通过宽范围的运动来移动减速装置的能力。在一个实施例中，材料减少工具围绕多个枢轴点在垂直平面中相对于底盘枢转。在一些实施例中，该装置包括位于与材料还原工具相对的装置的端部处的可伸缩辅助控制面板。控制面板使操作员可以从设备的端部引导设备的移动，从而使设备能够通过狭窄的空间进行操纵。
