摘要： A rotatable brush is located adjacent to and in contact with a ground engaging roller of a cutting unit of a mower to clean debris from the roller surface. The brush includes a brush shaft having at least one flight of brush bristles releasably secured to the brush shaft by a pair of fasteners. This permits easy replacement of the flight of brush bristles without having to replace the brush shaft. One end of the brush shaft is driven by a belt drive system with the driven end of the brush shaft passing through an elongated slot in a pivotally adjustable tensioning plate. The plate can be pivoted to adjust the tension in the drive belt without moving the driven end of the brush shaft, thus not affecting or changing the position of the brush relative to the roller. Drive can be imparted to the belt drive system using a hardened cap screw that is threaded into one end of the shaft of a rotatable reel on a reel cutting unit. The head of the cap screw mates in a non-circular socket on one end of a drive shaft to transfer power to the drive shaft and, thus, to the belt drive system.
摘要翻译：可旋转的刷子位于与割草机的切割单元的地面接合辊相邻并与之接触的位置，以清洁来自辊表面的碎屑。刷子包括刷轴，其具有通过一对紧固件可释放地固定到刷轴的刷毛的至少一个飞行。这样可以方便地更换刷毛的飞行，而无需更换刷轴。刷轴的一端由带驱动系统驱动，其中刷轴的从动端穿过可枢转地调节的张紧板中的细长槽。该板可以枢转以调节传动带中的张力而不移动刷轴的从动端，从而不影响或改变刷相对于辊的位置。可以使用硬化的盖螺钉将带驱动系统传递到带驱动系统，该螺钉拧入卷轴切割单元上的可旋转卷轴的轴的一端。盖螺钉的头部配合在驱动轴的一端的非圆形插座中，以将动力传递到驱动轴，从而传递到皮带驱动系统。

摘要： A plurality of annular collars are provided formed from collar halves. The collar halves are at least partially separable from one another to allow the collar halves to be slipped into and around a groove in a grooved roller for a reel-type cutting unit. The collar halves can then be abutted and secured together to substantially fill in the roller groove. When collars are placed into the last two or three grooves on each end of a grooved roller, a non-shouldered grooved roller is thereby converted into a shouldered grooved roller without having to remove and replace one set of rollers with another.
摘要翻译：由半部形成的多个环形套环。轴环半部彼此至少部分可分离，以允许轴环半部滑入带槽式切割单元的带槽滚轮中的槽内和周围。然后可以将半环接合并固定在一起以基本上填充在滚子槽中。当将套环放置在带槽辊的每一端上的最后两个或三个凹槽中时，非肩形沟槽辊由此转换成肩形沟槽辊，而不必将另一组辊移除并替换。

摘要： A reel gang mower has a row of front reel cutting units and a row of rear reel cutting units that cut an unbroken swath of grass in each pass. Each cutting unit is connected for propulsion to the mower frame by a four-bar linkage having front and rear pivot links that converge towards a focal point that establishes a virtual pull point through which propulsive force acts on the cutting unit. The rear pivot links can attach to the mower frame at a selected one of different attachment points to thereby longitudinally shift the pull point fore-and-aft relative to the center of gravity of the cutting unit, thus changing the fore-and-aft weight distribution. The rear cutting units in the gang can be configured to have a tail heavy weight distribution relative to the front cutting units to help eliminate marking in the overlap areas between the cutting units.

摘要： An articulating vehicle (10) includes a front axle (21) operatively connected to a front frame (40) and a rear axle (21) is operatively connected to the rear frame (30). A torsional joint (50) has an inner shaft member (51) operatively connected one of the frames and an outer hollow member (52) operatively connected to the other of the frames. An elastomeric material (53) is positioned between the inner member (51) and outer member (52). The elastic material (53) connects the inner and outer members, whereby the frames may rotate relative to each other along the longitudinal axis as the elastomeric member (53) is compressed and resiliently resists rotation between the frames (30 and 40). A torsional energy absorption suspension is provided for one of the wheels. The suspension includes a torsional joint (50), a single A-frame member (94). A lever arm (95) may also be utilized to vary the preload on the torsional joint (50).
摘要翻译：铰接车辆（10）包括可操作地连接到前框架（40）的前轴（21），并且后轴（21）可操作地连接到后框架（30）。扭转接头（50）具有可操作地连接其中一个框架的内轴构件（51）和可操作地连接到另一个框架的外部中空构件（52）。弹性体材料（53）位于内部构件（51）和外部构件（52）之间。弹性材料（53）连接内部构件和外部构件，由此当弹性构件（53）被压缩并弹性地抵抗框架（30和40）之间的旋转时，框架可以沿着纵向轴线相对于彼此旋转。为一个车轮提供扭转能量吸收悬架。悬架包括扭转接头（50），单个A框架构件（94）。杠杆臂（95）也可用于改变扭转接头（50）上的预载荷。
