摘要： A self-cleaning mounting system for a ground roller assembly to be used on a mower such as a flail mower including a stationary sleeve bearing positioned on mounting shafts extending from either end of the ground roller. The stationary sleeve bearing is positioned in a housing which is vertically positionably with respect to the mower housing. The housing includes a stationary helical flight and a seal guard which fits within the ground roller. The stationary sleeve bearing is protected on either end from dirt and debris getting between the inside surface of the stationary sleeve bearing and the outside surface of the mounting shafts on either end of the ground roller.

摘要： A height adjuster mechanism for mounting on a frame of a grass and/or ground treatment machine to vary the height of the frame relative to a ground-engaging roller assembly and thereby adjust the height setting of a grass and/or ground treatment module mounted on the frame. The mechanism includes an open-topped housing provided on a rotary adjuster and having an upper surface which defines a height adjustment reference datum level. An insert is movable up and down within the open-topped housing in which the upper surface of the insert can be adjusted to be substantially flush or coplanar with the upper surface of the open-topped housing so as to set a datum level of the treatment module. Means are provided for determining the extent of angular adjustment of the rotary adjuster so as to set any required height adjustment of the treatment module

摘要： A control system for a cutting reel unit includes a height-of-cut adjusting system and a reel-to-bedknife clearance adjusting system. The height-of-cut adjusting system includes a first frame; a second frame; a cutting reel supported by the second frame; a bedknife arranged adjacent to the cutting reel and supported by the second frame; at least one support element arranged to translate along the ground and arranged to support the first frame; and at least one first actuator connected between the first frame and the second frame and arranged to adjust the relative elevation of the second frame with respect to the first frame. The reel-to-bedknife clearance adjusting system includes at least one second actuator operatively connected between the reel and the second frame and a sound detector. DC electric rotary motors assemblies may be used to set the reel-to-bedknife gap and height-of-cut for the reel cutting unit. The DC electric rotary motors may be precisely controlled using position feedback sensors such as gear tooth sensors, and techniques known as pulse width modulation and/or “nudging.”

摘要： A user interface and control system for adjusting the reel of a cutting reel unit includes a frame supported by at least one support element that is supported on, and is movable along, the ground. The system also includes a cutting reel, a bedknife, first and second actuators, a controller, and an operator input station, all carried on the frame. The reel and bedknife define a cutting line therebetween. The first actuator is adjustable to set a clearance between the reel and the bedknife. The second actuator is operatively connected between the frame and the bedknife to adjust the elevation of the cutting line to set a height-of-cut of the cutting reel. The controller is signal-connected to the first and second actuators, to adjust the actuators. The operator input station is signal-connected to the controller, the operator input station including a keypad portion and a display portion, wherein the clearance and the height-of-cut are indicated on the display portion and the clearance and the height-of-cut can be selectively changed via the controller by operator input to the keypad portion.

摘要： A riser attachment for mower height adjustment includes a bracket attachable to a mower and a roller removably attachable to the brackets. Each bracket includes a cavity therein which receives an arm extending from a support structure which rotatably supports each end of the roller such as through an axle passing through a collar in an interface to which the arm is connected. The roller or other bearing surface extends below a mower support plane in which primary ground support structures of the mower are located. The roller or other bearing surface of the riser attachment thus elevates a cutting reel of the mower slightly to provide a second cutting height for the mower. This second cutting height can be adjusted through height adjusters which control a distance that the arms extend into the cavities of the brackets. Levers are rotatable to secure or release the arms within the cavities.

摘要： The present invention provides an improved height adjustment apparatus for controlling the operational height of lawnmowers and other turf maintenance equipment without the use of tools or removal and replacement of mechanical hardware. In one embodiment, the height adjustment apparatus includes a frame bracket that is attached to the frame with no relative movement therebetween, and a threaded rod threaded through the frame bracket. A nut is to the upper end of the rod. A swivel head is rotationally attached to the lower end of the rod, with the swivel head being attached to a ground contacting support. The apparatus further includes a socket configured to slidably receive the nut and the frame bracket. A biasing means is provided for slidably biasing the socket into a non-rotational aspect relative to the frame bracket. The height adjustment operation is initiated by slidably disengaging the socket from the frame bracket allowing the socket, nut and threaded rod to be rotated in the selected direction. The rotation of the threaded rod causes the rod to engage the threads of the frame bracket, resulting in the rod being screwed further in or out relative to the fixed position of the frame bracket. The movement of the rotating rod causes the distance between the frame bracket, and thus the frame itself, and the swivel head to change, thus changing the height of the operational unit relative to the ground contacting support and either increasing or decreasing the grass cut.

摘要翻译： 本发明提供一种改进的高度调节装置，用于在不使用工具或移除和更换机械硬件的情况下控制割草机和其他草坪维护设备的操作高度。 在一个实施例中，高度调节装置包括框架支架，该框架支架在其间没有相对运动地附接到框架，并且螺纹杆穿过框架支架。 螺母位于杆的上端。 旋转头旋转地附接到杆的下端，旋转头附接到地面接触支撑。 该装置还包括被配置为可滑动地容纳螺母和框架支架的插座。 偏置装置被设置用于相对于框架支架可滑动地将插座偏置成非旋转方面。 高度调节操作是通过将插座与框架支架滑动脱离开始的，允许插座，螺母和螺杆沿所选方向旋转。 螺杆的旋转导致杆接合框架支架的螺纹，导致杆相对于框架支架的固定位置进一步拧入或旋出。 旋转杆的运动导致框架支架之间的距离，因此框架本身与旋转头之间的距离发生变化，从而改变操作单元相对于地面接触支撑件的高度，并且增加或减少草切。

摘要： An improved snap-on height adjustment spacer clip is provided for height adjustment of wheeled frames including at least one ground-engageable wheel assembly. The snap-on clip includes a pair of mutually opposed, resiliently spreadable arms integrally connected at one end and disconnected at the opposite end. The clip arms are sized for embracing the spindle portion of the wheel assembly when installed, and are sized to permit the arms to yieldably flex toward and away from one another as the spindle passes transversely between the arms during installation and removal of the clip. The clip preferably includes a pair of mutually opposed, resiliently compressible hand knobs for use in clip installation and removal.
