摘要： A hydraulically powered implement is designed for use in connection with a tractor that has a hydraulic pump that supplies pressurized hydraulic fluid to the implement. The implement includes a variable displacement hydraulic motor, an operative element driven by the hydraulic motor, a speed sensor configured to measure the rotational speed of the operative element and output a speed signal representative of the measured speed, a shift module that adjusts the displacement of the hydraulic motor in response to a shift command signal, and a controller. The controller sends the shift command signal to the shift module in response to speed signal output by the speed sensor.

摘要： One stump cutter cutting wheel disclosed herein includes a wheel structure having left and right sides and being rotatable about a central axis extending between the left and right sides. The left and right sides define receptacles having depths measured in an orientation extending along the axis. Cutter assemblies are mounted to the wheel structure and include cutters mounted to cutter holders. The cutter holders include base portions that fit within the receptacles, and the base portions each define at least one fastener opening. The base portions further define base thicknesses measured in the orientation extending along the axis. The receptacle depths are at least 0.25 times as large as the base thicknesses such that no more than 75 percent of the base thicknesses extend laterally outside the receptacles. Fasteners secure the cutter holders to the wheel structure and extend through the fastener openings defined by the base portions.

摘要： A stump grinder is configured to mount to a portable machine that operably supports the stump grinder during a stump grinding procedure. The stump grinder includes a cutting wheel that is rotatably driven during the stump grinding procedure. The cutting wheel has a cutting surface to grind the stump by moving the rotating cutting wheel across the stump. A wheel stabilizing assembly is disposed between the portable machine and the drive system for supporting the drive system and cutting wheel. The cutting wheel is held in a generally vertical orientation and movement of the cutting wheel is biased relative to the portable machine. Accordingly, forces applied against the cutting surface of the cutting wheel during the grinding procedure are limited by the biased movement.
摘要翻译：树桩研磨机配置成安装到便携式机器，其可操作地支撑残端研磨过程中的残端研磨机。残端研磨机包括在残渣磨削过程中可旋转地驱动的切割轮。切割轮具有切割面，通过将旋转的切割轮移动通过树桩来研磨树桩。轮子稳定组件设置在便携式机器和驱动系统之间，用于支撑驱动系统和切割轮。切割轮保持在大致垂直的方向，并且切割轮的运动相对于便携式机器偏置。因此，在研磨过程中施加在切割轮的切割表面上的力受到偏置运动的限制。
