摘要： A mowing mechanism having a spindle rotatively driven by a power source, a blade having a radially inner portion coupled for rotation with the spindle and a radially outer portion for cutting vegetation, a housing within which the blade rotates, and a disc operatively carried within the housing for rotation with the blade and having a radially outer portion spaced above the blade. The disc includes an inner portion extending radially inwardly from the outer portion to a position proximate the blade, the inner and outer portions of the disc serving to confine air and clippings near the outer portion of the blade. The rotating disc prevents accumulation of the grass clippings beneath the disc and housing, and enhances airflow within the housing due to viscous drag or friction between the disc and the air within the housing. Deflectors carried by the disc are designed to further enhance airflows and generally deflect clippings back toward the blade for mulching.

摘要： An improved knob for attachment to a lever or the like having a knob body with a cavity formed therein, an extension operatively attached to the body and being biased toward the cavity. Operatively attached to the extension is a projection for engaging a mating portion on the lever and a tapered portion for enabling the knob to be easily removed from the lever. The preferred knob has the extension connected to the knob body so that the extension does not project very far below the cavity entrance. The knob of the present invention is preferably manufactured by injection molding in a single step operation. Once cured, the knob is removed from the mold in condition for assembly on an appropriate lever or the like. To effectuate assembly, an assembler simply places the knob on the lever or the like until the projection engages a mating portion thereof.

摘要： A mechanism including a plurality of baffles positioned within a mower housing between the mower blades and a rear discharge outlet, including a first wall adjacent the edge of a respective blade and which acts to define the chamber within which the blade rotates, a second wall extending rearwardly from the first wall and defining chutes which extend between the chambers and the rear discharge outlet, and third surfaces which act to enclose the space between the first and second walls to thereby prevent air and clippings from accumulating there. The chutes generally converge at the rear outlet. Ramps are positionable within the chutes for changing the mower to a mulching mode, and include a fourth wall or surface positioned in the entrance to the chute for partially blocking air and clippings from entering the chute. A fifth surface extends rearwardly from the edge of the fourth surface to the discharge outlet. A deflector is positionable within the housing and acts to channel clippings downwardly into the blade for re-cutting at a first portion, reduce the effective volume within the chamber at a second portion, and increase the vacuuming effect at a third portion. A first blade includes a plurality of upstanding nubs which are received in respective openings formed in the second blade, and act to couple the second blade for rotation with the first blade.
摘要翻译：一种机构，包括多个挡板，其位于割草机壳体内的割草机叶片和后排出口之间，包括与相应叶片的边缘相邻的第一壁，并且用于限定叶片旋转的室;第二壁延伸从第一壁向后并且限定在室和后排出口之间延伸的滑槽，以及用于封闭第一和第二壁之间的空间的第三表面，从而防止空气和夹子在那里积聚。滑槽通常会聚在后出口处。坡道可在滑槽内定位，用于将割草机更换为覆盖模式，并且包括位于滑槽入口中的第四壁或表面，用于部分阻挡空气和夹子进入滑槽。第五表面从第四表面的边缘向后延伸到排出口。偏转器可定位在壳体内并且用于将夹子向下引导到叶片中以在第一部分处重新切割，在第二部分减小腔室内的有效体积，并且在第三部分增加抽真空效果。第一刀片包括多个直立的凸块，其被接收在形成在第二刀片中的相应开口中，并且用于将第二刀片与第一刀片联接。

摘要： A mower having a belt tensioner that includes a belt engaging primary pulley swingably supported by a primary arm. A rod coupled to the arm carries a spring that acts to push the pulley into engagement with the belt. The rod acts to pull the pulley away from the belt to release the tension in the belt for removal of the belt. A handle attached to the rod is turned by the operator to positively swing the pulley away from the belt. The handle may also be gripped by the operator's hand to lift that portion of the deck during operation to avoid gouging irregular ground conditions or striking obstructions.

摘要： A mechanism for mounting a wheel to a mower deck having a mounting arm carrying a bolt. First bushings fitted within the wheel rotate about a sleeve fixed to the bolt. Second bushings adjacent the first bushings transfer axial forces from the wheel to the mounting arm. The second bushing is recessed within the first bushings in one embodiment, and within the wheel in another embodiment. Seals are formed between the second bushing and the first bushing in one embodiment, and between the second bushing and the wheel in the other embodiment in order to keep dirt and debris from coming between the contacting surfaces during operation.
