摘要： A carriage assembly includes a primary frame, a first idler wheel mounted to the primary frame, and a secondary frame pivotably mounted to the primary frame. The carriage assembly further includes an idler wheel assembly coupled to the secondary frame and movable with respect to the secondary frame along a longitudinal axis of the idler wheel assembly. The idler wheel assembly includes at least one second idler wheel and at least one third idler wheel mounted to the idler wheel assembly such that the second idler wheel is located between the first idler wheel and the third idler wheel. The first idler wheel is configured to pivot with the primary frame relative to the secondary frame, and the second idler wheel and the third idler wheel are configured to move with the idler wheel assembly relative to the secondary frame along the longitudinal axis of the idler wheel assembly.

摘要： A powered stump grinder at the center front of a walk-behind machine is disclosed. The grinder machine has a front cutter head assembly pivotally connected to the walk-behind machine by a central pivot assembly connected to the center front part of the frame or body of the machine. The central pivot assembly includes a vertical pivot axle/axis, for lateral movement of the connected front cutter head assembly. Generally horizontal hydraulic cylinders, extending between a frame or body of the stump grinder and left and right lateral portions of the pivot assembly, pivot horizontally and extend and retract to control lateral movement of the connected front cutter head assembly by pivoting the pivot assembly, which in turn pivots the connected cutter arm, and hence, the cutter head assembly.

摘要： Disclosed devices, systems, and methods allow an operator to maintain the speed of a vehicle's propulsion devices at selected speeds, and allow the operator to make adjustments to the selected speeds during or prior to operation of the vehicle. Disclosed embodiments can comprise adjustable limiters that are coupled to the control portion of the vehicle adjacent to or on the speed control levers. This allows the operator to hold the levers against a new limiting surface to keep the vehicle moving at a speed that is less than full speed with minimal aberration and less effort needed by the operator. The device can be adjustable to a range of positions corresponding to different speeds. The devices can also be selectively pivoted or moved out of the way of the speed control levers at any time to allow the levers to have their full range of motion.

摘要： Disclosed systems couple two rotational shafts in axial alignment with each other such that torque can be transferred between the shafts without undesired loading occurring. A shaft coupling system can include an annular mounting housing positioned around a juncture of two rotational shafts with bearings positioned between the shafts and the housing so that the housing prevents radial motion of the shafts while allowing the shafts to rotate about their common axis. One shaft can be coupled to an engine and the other shaft can be coupled to a shaft-driven device such as a hydraulic pump. One shaft can be smaller in diameter and piloted into a recess in the end of the other shaft. In some embodiments, the two shafts have about the same diameter and are linked via a torque coupler within an annular mounting housing that allows rotation but limits radial motion of the shafts.

摘要： A carriage assembly for a continuous track drive system can include a plurality of road wheels, a pivotable idler wheel, a drive wheel, a continuous track extending around the plurality of road wheels, the pivotable idler wheel, and the drive wheel, and a tensioning system coupled to the idler wheel. The tensioning system can include an actuator and a biasing member. The tensioning system can be configured such that when the continuous track is driven in a first direction the actuator is inactive and the biasing member maintains tension in the continuous track, and when the continuous track is driven in a second direction the actuator is active and applies force to the pivotable idler wheel to maintain tension in the continuous track.

摘要： Disclosed herein are devices, systems, and methods that allow an operator to maintain the speed of a vehicle's propulsion devices at selected speeds that are less than full speed, and allow the operator to make adjustments to the selected speeds during or prior to operation of the vehicle. Disclosed embodiments can comprise adjustable limiters that are coupled to the control portion of the vehicle adjacent to or on the speed control levers. These devices can be set to a selected position to provide a stop that limits the levers to a modified maximum position that is different from the normal maximum, full-speed position. This allows the operator to hold the levers against a new limiting surface to keep the vehicle moving at a speed that is less than full speed with minimal aberration and less effort needed by the operator. The device can be adjustable to a range of positions corresponding to different speeds, and each lever can have its own limiting device to set an independent modified-maximum speed for each propulsion device of the vehicle. The devices can also be selectively pivoted or moved out of the way of the speed control levers at any time to allow the levers to have their full range of motion.
摘要翻译： 这里公开的是允许操作者以小于全速的选定速度保持车辆推进装置的速度的装置，系统和方法，并且允许操作者在操作期间或之前对所选择的速度进行调整 车辆。 公开的实施例可以包括可调节的限制器，该限制器联接到车辆的控制部分，其与速度控制杆相邻或在速度控制杆上。 这些设备可以设置在选定的位置，以提供一个停止，将停车限制在与正常最大全速位置不同的修改的最大位置。 这允许操作者将杠杆保持在新的限制表面上，以保持车辆以小于全速的速度移动，同时具有最小的像差和较少的操作者需要的努力。 该装置可以调整到对应于不同速度的一定范围的位置，并且每个杠杆可以具有其自己的限制装置，以为车辆的每个推进装置设定独立的修改最大速度。 该装置还可以随时选择性地枢转或移出速度控制杆的方式，以允许杠杆具有其全部运动范围。
