摘要： A string trimmer provides a cutting head having a passage therethrough receiving a cutting element of fixed length. The cutting element includes a monofilament line and a resilient sleeve surrounds one end of the monofilament line. A rigid eyelet in one end of the resilient sleeve provides an external upset or abutment which cooperates with a shoulder or restriction in the passage to retain the cutting element in the passage during cutting. A groove in the periphery of the cutting head intersects the passage and provides a recess for wholly receiving the cutting element if the user positions the cutting head against an immovable obstacle.

摘要： There is disclosed a technique for modifying a conventional rotary lawn mower to provide the capability of cleaning a paved area such as a sidewalk or driveway. Basically, the only modification to the lawn mower is the provision of a depending skirt extending downwardly from a peripheral wall of the lawn mower frame. Three embodiments are illustrated. The first embodiment comprises a skirt mounted on the lawn mower frame for adjusting movement between an upper or grass cutting position and a lower or sweeping position in which the lower edge of the skirt is spaced only slightly above the bottoms of the lawn mower wheels. The second embodiment comprises a skirt fixed to the lawn mower frame. Adjustment of the skirt to a lower sweeping position is accomplished by the provision of conventional adjustable wheels which effectively lower the lawn mower frame relative to the ground. The third embodiment comprises a skirt which is attached to the lawn mower only when it is desired to perform a sweeping function.

摘要： There is disclosed a technique for modifying a conventional rotary lawn mower to provide the capability of cleaning a paved area such as a sidewalk or driveway. Basically, the only modification to the lawn mower is the provision of a depending skirt extending downwardly from a peripherial wall of the lawn mower frame. Three embodiments are illustrated. The first embodiment comprises a skirt mounted on the lawn mower frame for adjusting movement between an upper or grass cutting position and a lower or sweeping position in which the lower edge of the skirt is spaced only slightly above the bottoms of the lawn mower wheels. The second embodiment comprises a skirt fixed to the lawn mower frame. Adjustment of the skirt to a lower sweeping position is accomplished by the provision of conventional adjustable wheels which effectively lower the lawn mower frame relative to the ground. The third embodiment comprises a skirt which is attached to the lawn mower only when it is desired to perform a sweeping function.

摘要翻译： 公开了一种用于修改常规旋转割草机以提供清洁诸如人行道或车道的铺设区域的能力的技术。 基本上，割草机的唯一修改是提供从割草机框架的外围壁向下延伸的悬垂裙。 示出了三个实施例。 第一实施例包括安装在割草机框架上的裙部，用于调节上切割或切草位置与下部或扫掠位置之间的运动，其中裙部的下边缘仅间隔开在割草机轮的底部。 第二实施例包括固定到割草机框架的裙部。 通过提供有效地降低割草机框架相对于地面的常规可调节轮来实现裙部到较低扫掠位置的调节。 第三实施例包括仅当需要执行扫掠功能时才连接到割草机的裙部。
