摘要： A lawn mower having a cutter housing made of a synthetic resin. The cutter housing has side guard parts provided on left and right peripheries of a scroll part. Each side guard part has a hollow reinforcing part. The hollow reinforcing part is made up of a side wall of the scroll part, an approximately horizontal guard wall formed on the side wall, and a connecting rib connecting together the guard wall and the side wall. The reinforcing part makes the cutter housing resistant to impacts from the sides and to bending with respect to its length direction.

摘要： An improved mounting arrangement for a knife to a disc for use on a rotary disc cutter that eliminates the need for a threaded connector and the associated nut is disclosed. It also provides a positive retention method on the top side of the disc. In addition, it provides a method of removing the knife from the disc without the use of wrenches, simply requiring a tool for prying, such as a screw driver. A further feature is a low profile retainer that does not need to be protected by a wear protector.

摘要： An inexpensive and readily available pruning blade for pruning crop growth, such as grape vines following harvest, has a disc-like base plate. The base plate has ordinary small diameter radial Skil-saw blades mounted around the periphery. The saw blades are fixed rotationally on the base plate by a clamp and have a portion of the saw teeth extending beyond the base plate periphery so that rotation of the base plate induces cutting action by the saw teeth at the periphery of the base plate. When the extending saw teeth become dull, the clamp is loosened, the saw blade is rotated through an arc sufficient to expose sharp teeth at the base plate periphery, and the clamp is tightened.

摘要： A zero turning radius power lawn mower for operation by a standing occupant includes first and second independently driven and controlled rear drive wheels mounted on separate drive axles. A riding platform for supporting the standing occupant or operator is located between the first and second rear drive wheels. The rear drive wheels are independently driveable in both the forward and reverse directions at variable speeds so as to allow for substantially zero radius turning of the mower about a central turning point. The riding platform is positioned near this turning point or axis so that the standing occupant remains substantially unaffected by centrifugal force created during approximate zero radius turning of the mower thereby allowing the mower to take such turns at higher speeds. The low center of gravity created by the position of the riding platform for the standing operator also results in the mower having improved traction and being less likely to pop nullwheeliesnull upon acceleration.

摘要翻译： 用于由站立乘员操作的零转弯半径功率割草机包括安装在单独驱动轴上的第一和第二独立驱动和受控的后驱动轮。 用于支撑站立乘客或操作者的骑乘平台位于第一和第二后驱动轮之间。 后驱动轮可以以可变速度在前后方向上独立地驱动，从而允许割草机围绕中心转折点基本上为零半径的转动。 骑乘平台位于该转折点或轴线附近，使得站立乘员基本上不受由割草机近似零半径转动期间产生的离心力的影响，从而允许割草机以更高速度进行这种转弯。 由立式操作者的骑乘平台的位置产生的低重心也导致割草机具有改进的牵引力，并且在加速时不太可能弹出“轮椅”。

摘要： A deep groove ground-contacting roller for a reel type mower assembly having a plurality of interfitting intermediate roller segments and matching end segments mounted on a transverse bearing mounted axle rod in tight abutment. Stop rings engage the end segments and the axle rod to fix the roller segments on the rod to form a roller body. Each roller segment includes a cylindrical hub and a disc element extending radially therefrom with converging planar annular side surfaces intersecting to form a rounded ground-contacting ridge. The disc elements and the hub sections combine to form a deep groove with angled side surfaces and a right circular cylindrical bottom.

摘要： A mulching mower deck within which first and second mower blades rotate for cutting grass, having first and second blade chambers positioned adjacent each other and within which respective blades rotate during operation. The first and second blade chambers are generally completely enclosed for generally confining grass clippings within the blade chambers for preventing the clippings from exiting through side or top walls of the mower deck. The first and second blades travel in respective paths which overlap. The first blade is positioned to the right of the second blade with respect to forward operation of the mower deck and travels in a clockwise direction, and the second blade is positioned to the left of the first blade and travels in a counterclockwise direction. An opening is formed between the first and second blade chambers at a location where the blade paths overlap. Edges of the opening are positioned relatively close to the first and second blades near where the blade paths overlap. A flow divider defines the opening and is positioned generally above the location where the blade paths overlap, and extends downwardly from the top wall of the mower deck to a position in relatively close vertical proximity to the rotating blades where the blade paths overlap. The flow divider includes a portion directly in front of where the blade paths overlap, which acts to divide and direct air and clippings to respective blade chambers.
摘要翻译： 一种覆盖的割草机甲板，其中第一和第二割草机叶片旋转以切割草，其中第一和第二叶片室彼此相邻定位，并且各个叶片在操作期间旋转。 第一和第二叶片室通常被完全封闭，以将草屑大致限制在叶片室内，以防止剪切通过割草机甲板的侧壁或顶壁离开。 第一和第二叶片在相互重叠的相应路径中行进。 第一叶片相对于割草机甲板的向前操作定位在第二叶片的右侧并沿顺时针方向行进，并且第二叶片位于第一叶片的左侧并沿逆时针方向运动。 在叶片路径重叠的位置处，在第一和第二叶片室之间形成开口。 开口的边缘被定位成相对靠近叶片路径重叠的第一和第二叶片。 分流器限定开口并且大致位于叶片路径重叠的位置的上方，并且从割草机顶板的顶壁向下延伸到与叶片路径重叠的旋转叶片相对接近垂直的位置。 分流器包括直接在叶片路径重叠的前方的部分，其用于将空气和夹子分配并引导到相应的叶片室。

摘要： A circular brush cutting blade with peripheral cutting teeth. Segments are bent or deflected out of the blade body at an angle to the plane of the blade less than normal. The segments are configured to provide an inclined leading edge for each segment that cuts a laterally extended path with movement of the blade laterally or axially. The segments produced by folding the segments around a base line or juncture with the blade body whereby the opening through the blade created thereby is radially outward of the juncture.
