摘要： A triplex trim mower (100) including a vehicle (102) having two front drive wheels (104) and one rear steerable wheel (106). Mounted generally forward of the front wheels (104) are two reel-type cutting units (108a) laterally offset about the longitudinal axis (110) of the vehicle (102). Mounted between the front and rear wheels and substantially centered between the forward cutting units (108a) is a rear reel-type cutting unit (108b). A lateral support frame (137) is incorporated into the main frame of traction vehicle (102). The cutting units (108) are supported by a lateral carrier frame (144) which is slidably engaged to lateral support frame (137) such that carrier frame (144) can move laterally relative to support frame (137). A hydraulic cylinder (158) permits carrier frame (144) to be laterally displaced under operator command. Second and third hydraulic cylinders (131) permit cutting units (108) to be moved between a transport position and an operating position. A single joystick (118) permits the operator to control all aspects of cutting unit position including transport or operating position and lateral offset position.

摘要： One aspect of the invention relates to a cutting unit joint (22) which can be located between a lift arm (18) and a cutting unit (20). Cutting unit joint (22) includes a four-bar linkage preferably including pairs of pivoting links (46 and 48) which create a "virtual pull point" at any desired location. With regard to one embodiment, a cutting unit (20), the virtual pull point is even located below ground, when the cutting unit (20) is generally level. This configuration reduces or eliminates cutting unit "bobbing." In another embodiment, in connection with a cutting unit (20'), the virtual pull point is located roughly at the centerline of the reel, to maintain a good "seal" between the cutting unit (20') and a lift arm supported grass basket (52'). Another aspect of the present invention relates to a self-contained damper (76) connected to lift arm (18), the damper (76) resisting upward movement at a velocity or frequency consistent with cutting unit "bobbing."

摘要翻译： 本发明的一个方面涉及一种可以位于提升臂（18）和切割单元（20）之间的切割单元接头（22）。 切割单元接头（22）包括优选地包括成对的枢转连杆（46和48）的四杆连杆，其在任何所需位置处产生“虚拟拉点”。 关于一个实施例，当切割单元（20）大致水平时，切割单元（20），虚拟拉点甚至位于地下。 这种配置减少或消除了切割单元“摆动”。 在另一个实施例中，与切割单元（20'）相连，虚拟拉点大致位于卷轴的中心线处，以便在切割单元（20'）和提升臂支撑的草（20'）之间保持良好的“密封” 篮子（52'）。 本发明的另一方面涉及连接到提升臂（18）的独立式阻尼器（76），所述阻尼器（76）以与切割单元“摆动”一致的速度或频率阻止向上运动。

摘要： A core processor comprises a frame that supports a housing. The housing carries a rotary pulverizer inside a semi-cylindrical drum and a rotary pick up brush in a pick up head below the drum. The drum is open at the rear to form a rear discharge opening. The pick up head includes a full width rear roller behind the brush to support the housing for rolling movement over the ground in a work mode of the processor. In the work mode, the brush picks up aeration cores from the ground, delivers them to the rotary pulverizer which comminutes or pulverizes the aeration cores, and the particle debris so created exits through the rear discharge opening beneath a hood or shroud. A powered roller is located at a junction between the orbits of the brush and the pulverizer to help keep the junction free of a build up of core material. In a transport mode of the core processor, a pair of transport wheels are lowered into engagement with the ground until the pick up head is lifted out of engagement with the ground.

摘要翻译： 核心处理器包括支撑壳体的框架。 外壳在旋转式粉碎机内装有旋转式粉碎机，位于滚筒下方的拾取头中的半圆柱形滚筒和旋转拾取刷内。 鼓在后部打开以形成后排出口。 拾取头包括刷子后面的全宽度后辊，以支撑壳体，以在处理器的工作模式下在地面上滚动运动。 在工作模式下，刷子从地面拾取曝气芯，将其传送到旋转粉碎机，粉碎机粉碎或粉碎曝气芯，并且所产生的颗粒碎屑通过罩或罩下方的后排出口离开。 动力辊位于刷子和粉碎机的轨道之间的连接处，以帮助保持接合点不会堆积芯材料。 在核心处理器的传送模式中，一对传送轮被降下成与地面接合，直到拾取头被提升离开与地面接合。

摘要： A debris sweeper has a powered rotary brush for sweeping debris, such as aerator cores, from a turf surface into a debris collecting hopper. The brush and hopper are carried on a wheeled tow frame. The hopper is pivotally supported on a pivotal lift frame that moves the hopper between a lower, debris collecting position and an upper, debris dumping position. The lift frame pivots on the tow frame behind an axis of a pair of wheels while the hopper pivots on the lift frame in front of the wheel axis. This ensures that positive weight is kept on the tongue of the tow frame at all times.

摘要翻译： 垃圾清扫机具有动力旋转刷，用于从草皮表面扫掠碎屑（例如曝气芯）到碎屑收集料斗中。 刷子和料斗被装在轮式拖车框架上。 料斗枢转地支撑在枢转提升架上，该框架使料斗在较低的碎屑收集位置和上部碎屑倾倒位置之间移动。 提升架在一对轮子的轴线后面的拖链框架上枢转，同时料斗在车轮轴线前方的提升架上枢转。 这确保了始终在丝网框架的舌头上保持正重。
