摘要： A mower includes a traction frame that supports at least one cutting unit and a grass catcher associated with each cutting unit. The cutting unit and grass catcher are both operatively coupled to the traction frame such that they both jointly are able to steer or yaw together during turns of the traction frame. This permits the gap between the cutting unit and a grass basket which is part of the grass catcher to remain constant whether the traction frame is travelling straight or is turning. This ensures that the grass clippings will be properly retained in the grass basket without dribbling out of the grass basket. In addition, a system is provided for keeping the grass catcher level as it is lifted up out of engagement with the ground into a raised, transport position, also to better retain the grass clippings within the grass basket.
摘要翻译： 割草机包括支撑至少一个切割单元和与每个切割单元相关联的割草器的牵引框架。 切割单元和割草器都可操作地联接到牵引框架，使得它们在牵引框架的转动期间共同地能够转向或偏转在一起。 这允许切割单元和作为捕捉器一部分的草篮之间的间隙保持恒定，无论牵引架是直线行驶还是正在转动。 这样可以确保将草屑适当地保留在草篮中，而不会从草篮中运出。 另外，还提供了一种系统，用于保持草地捕获器的水平，因为它与地面的接合提升到升高的运输位置，同时也更好地将草屑保持在草篮内。

摘要： A high pressure liquid containment joint in an apparatus for injecting high pressure liquid into turf. A preferred high pressure liquid containment joint includes an O-ring (72). The high pressure liquid containment joint also includes a cylindrical plug (70). The plug (70) includes a first end and a second end, external threads (71) located between the first and second ends, a shoulder (73) for accepting the O-ring (72) wherein the shoulder (73) is located between the external threads (71) and the second end. The plug (70) also includes a hexhead (75) connected with the first end for accepting rotational force. The high pressure liquid containment joint also includes a high pressure liquid containment vessel for containing high pressure liquid wherein the vessel includes a threaded bore (74) wherein the bore (74) includes internal threads (172) for engaging the external threads (71) and two, smooth machined frusto-conical surfaces (174, 175) for contacting the O-ring. The O-ring (72) and the frusto-conical surfaces (174, 175) form a liquid impermeable barrier when the external threads (71) engage the internal threads (172) and the plug (70) and the O-ring (72) are rotated relative to the threaded bore (74) and wherein the barrier lies between the high pressure liquid and the external and internal threads (71, 172) whereby stresses on the internal threads (172) in the containment vessel are reduced resulting in a reduced chance of structural failure of the containment vessel.

摘要： A reel mower has a double A arm suspension that lowers a reel cutting unit into a cutting position in a tail down orientation and that levels the reel cutting unit out as it lifts the reel cutting unit into a transport position. The reel cutting unit yaws during turns about a substantially vertical axis having a negative caster angle. The suspension has clamps that can be flipped open or closed to quickly attach or detach the reel cutting unit. A drive motor can be quickly attached or detached to the reel cutting unit using a pivotal wire form. An active counterbalance system automatically offsets the increasing weight of a grass basket on the reel cutting unit to maintain quality of cut. The grass basket maintains a constant spacing relative to the reel cutting unit when the reel cutting unit pitches to improve clipping collection.

摘要： A bag support for a riding lawn mower grass collector includes a rectangular framework (2) attached to a mower (10) with grass directing hood (4). A grass bag (6) has a resilient frame (8) extending substantially around bag opening (40). A much larger leaf bag (80) has a resilient frame (82) extending substantially around bag opening (40'). Frames (8, 82) include three continuous coplanar sides and a fourth side with a central open space (44, 86) bounded by a pair of handles (12, 12') extending perpendicularly outward from frame (8, 82). The sections of the fourth side adjacent open space (44, 82) are at an acute angle to the plane of the three coplanar sides. Frames (8, 82) are configured to match separate portions of framework (2). Framework (2) includes transverse brackets (14) and (16) at locations to correspond with alternate sizes of bag (6) or (80). Handle retaining brackets (18) are attached to rear of framework (2) to receive handles (12, 12'). Brackets (18), resilient frame (8, 82), brackets (14) or (16) and angled segments (45, 87) of the fourth side of frames (8, 82) cooperate to provide a sealing engagement between framework (2) and matching frames (8, 82). Framework (2) can thus support a plurality of small bags (6) or a single larger bag (80) by utilizing brackets (14) or (16), respectively.
