摘要： The present invention provides a lawn mower blade spindle assembly which can be easily serviced in the field, which includes a blade height adjustment feature which allows a blade to be replaced or be adjusted without removing the blade spindle bearings. An improved stress loading arrangement is further provided which reduces spindle stress and lessens the opportunity for spindle assembly failure upon catastrophic blade impact with an immovable object such as with a rock.

摘要： A mower blade suitable for bagging, side discharge and mulching is provided. A laterally upswept outboard cutting portion cuts the grass and sucks the clippings upwardly. The clippings are forced by the combined effects of the upswept outboard cutting portion and an upswept inboard cutting portion into an intermediate cutting portion where they are further comminuted and are then sucked back into both the outboard cutting portion and the inboard cutting portion. These double circulation paths result in excellent comminution and superior hiding of the clippings.

摘要： Disclosed herein is a marine propulsion device which comprises an engine having an exhaust port for discharging exhaust gas, and which also comprises a lower unit having an exhaust tube in communication with the exhaust port. The lower unit includes a cavitation plate submerged in water during idle engine operation, and an exhaust outlet in communication with the exhaust tube. The exhaust outlet affords discharge of the exhaust gas below the cavitation plate. The lower unit includes an outer wall including an outlet, which outer wall outlet is located above the cavitation plate and submerged in water during idle engine operation. The lower unit also incudes a passage in communication with the exhaust tube and the outer wall outlet. The passage affords, during reverse engine operation, discharge of a portion of the exhaust gas from the exhaust tube out the outer wall outlet.

摘要： A flail head for a vegetation cutter having face-to-face cup shaped central body portions separated by a predetermined distance Symmetrically spaced pivot posts extend between the face-to-face central body portions. A fail blade is pivotably attached to each pivot post. In one embodiment of the flail head, the face-to-face body portions are identical and the pivot posts are formed by mating semi-cylindrical posts formed integrally with each of the central body portions. The flail blades and body portions are made from different plastic materials to prevent the fusion or welding of the flail blades to the posts.

摘要： A line trimmer head assembly having a central hub and a body including an annular disc extending circumferentially radially outward from the central hub to removably receive the length of a uniform cross-section line. The disc member is provided with a pair of openings on the disc periphery through which a fixed line length is threaded. The interior portion of the disc is provided with at least two retainer clips having a hook shaped member with an incline ramp surface for cooperating with the portion of the line extending between the two openings. The line is held in place by tension which causes the line to travel down the ramp surface.

摘要： In a filament type trimmer a filament is wound on a storage spool in a rotating housing and exits through an opening in a rim portion of the housing. When the extending portion of the filament is rotating freely, it extends approximately radially from the housing. However, when it hits a relatively stationary object, it is deflected rearwardly so as to extend approximately tangentially from the housing. To avoid high stresses in the exiting portion of the filament, the exit opening is inclined rearwardly so that when the filament is deflected rearwardly by striking an object, it extends in a tangential line off of the spool, thereby avoiding bending stresses at the exit opening.

摘要翻译： 在丝线型修剪器中，灯丝缠绕在旋转壳体中的存储卷轴上并且通过壳体的边缘部分中的开口离开。 当长丝的延伸部分自由旋转时，其大致径向地从壳体延伸。 然而，当它撞到相对静止的物体时，它向后偏转，从而从壳体大致切向延伸。 为了避免灯丝退出部分的高应力，出口开口向后倾斜，使得当灯丝通过撞击物体向后偏转时，它以切线离开卷轴延伸，从而避免出口处的弯曲应力 。
