摘要： A rotary mower (10) including a front deck assembly (18) and a pair of wing decks (20). Each wing deck (20) is supported by a lift arm assembly including a main lift arm (26) and a lift arm extension (32). A pivot joint (30) exists between lift arms (26) and (32) so that when deck (20) is raised from its cutting position to its transport position it is also caused to rotate so that mower (10) maintains a relatively low profile even when decks (20) are in their transport position. Mower (10) also preferably includes a pair of breakaway assemblies (48) which allow wing decks (20) to "break away" in the event they strike an immovable object. Finally, a preferred mower (10) includes resilient bushing assemblies (38) between the wing deck lift arm assemblies and the wing deck housings (24) to minimize vibration and noise and provide some floating of the decks (20).
摘要翻译：一种旋转割草机（10），包括前甲板组件（18）和一对翼板（20）。每个翼甲板（20）由包括主提升臂（26）和升降臂延伸部（32）的提升臂组件支撑。枢轴接头（30）存在于提升臂（26）和（32）之间，使得当甲板（20）从其切割位置升高到其运送位置时，其也被转动，使得割草机（10）保持相对较低即使在甲板（20）处于运输位置时也是如此。割草机（10）还优选地包括一对分离组件（48），其允许翼甲板（20）在它们撞击不可移动的物体的情况下“脱离”。最后，优选的割草机（10）包括在（24）之间的弹性衬套组件（38），以最小化振动和噪音并提供甲板（20）的一些浮动。

摘要： A walk aerator comprises a frame supported by a plurality of ground engaging wheels, the frame carrying a coring head having a plurality of side-by-side tine assemblies. The wheels define a wheelbase which is substantially equal to or less than the width of a coring swath and the wheels are located in advance of the coring head to keep the wheels from passing over the holes or soil cores left in any preceding coring swathes formed by the aerator. The vertical position of the coring head is adjustable up and down as the ground contour changes to keep hole depth substantially constant. The tine assemblies are reciprocated by a single crankshaft driven by a single pulley, the crankshaft being assembled from multiple crank arms that are splined and bolted together. Sealed bearings connect drive arms that drive the tine assemblies to the crankshaft. The crankshaft can be disassembled to allow the sealed drive arm bearings to be replaced. Integral core deflectors are used on the drive arms. A connecting link extending across each drive arm is used to connect each drive arm to the coring head to decrease the coring head depth.
摘要翻译：步行充气机包括由多个地面接合轮支撑的框架，该框架承载具有多个并排齿组件的取心头。车轮限定了基本上等于或小于取芯条的宽度的轴距，并且车轮位于取心头之前，以保持车轮不会通过留在任何先前取芯片中的孔或土芯，曝气机。取心头的垂直位置随着地面轮廓的变化而上下可调，以保持孔深度基本恒定。齿组件由单个由单个滑轮驱动的单个曲轴往复运动，曲轴由多个曲柄臂组装而成，该曲柄臂花键并且螺栓连接在一起。密封轴承将将齿轮组件驱动到曲轴的驱动臂连接。可以拆卸曲轴，以便更换密封的驱动臂轴承。驱动臂上使用了一体的磁芯偏转器。使用延伸穿过每个驱动臂的连接链路将每个驱动臂连接到取芯头以减小取芯头深度。

摘要： A riding mower (2) includes a cutting unit (6) suspended from a traction unit (4). Cutting unit (6) is suspended from a forwardly extending frame (8) by four suspension units (40-43). Each suspension unit includes an upwardly opening saddle member (44) in which a pin (51) carried on cutting unit (6) is received. At least some of the pins (51) are longitudinally constrained in the saddle members (44) to longitudinally couple cutting unit (6) to frame (8). This allows cutting unit (6) to move upwardly relative to frame (8) at each of the suspension units to allow the cutting unit (6) to tilt or float relative to frame (8).

摘要： A foot pedal is mounted on a control lever operatively connected to a hydrostatic transmission mechanism for a vehicle, for controlling forward and rearward movement of the vehicle. A damping member, operatively associated with the control lever, frictionally engages the pedal to restrain movement of the pedal and control lever, which movement may be caused by heavy vibration of the vehicle during travel over uneven terrain.

摘要： A tine holder for holding a plurality of aerator tines has a plurality of substantially vertical, tapered bores. A tapered collar is adapted to be received in each bore with the collar being split so that the collar contracts as the collar is slid into the bore. The upper end of an aerator tine is inserted into each collar before the collar is inserted into the bore such that the contraction of the collar as the collar is thereafter slid into the bore will suffice to tightly grip and hold each tine in the tine holder. A tool is provided for providing enough leverage on the collar to slide the collar over final portions of its movement as the collar slides into the bore during tine installation or to slide the collar over beginning portions of its movement as the collar slides out of the bore during tine removal.

摘要： A heating coil assembly for use in an air blower device has an annular support element, a first end cap, a core having a heating coil spirally wound thereon, a sleeve surrounding the coil and core, and a second end cap. All components have a centrally disposed non-circular bore therein for receiving a heavy gauge non-circular wire retainer, swaged at one end, which extends through the entire assembly and is retained by a press washer at an opposite end. The interior of the sleeve is spaced from the coil forming an axial channel for air flow over the coil. Axial openings in the end caps form air inlets and outlets for the channel. The coil has several leads, at least one of which extends through an axial opening in one of the end caps. The heating coil assembly has a small number of components, which are easily assembled and simultaneously axially and radially positioned and retained relative to each other by the wire retainer.
