摘要： A mobile lawn mower is designed multi-part in that the four-wheel carriage housing is provided with a center opening for lockable accommodation of a self-acting so-called grass trimmer, such design permitting operation of the lawn mower as such or the use of the grass trimmer by itself.

摘要： Lawn clippings are pelletized and distributed back onto the lawn directly, for example, as part of a mowing operation. For this purpose the lawn clippings are supplied into the top of a chamber wherein compression rollers press the clippings through a stationary apertured plate for extruding the clippings in the form of compressed strands. A rotating distribution disk is arranged below the plate for breaking up the strands into pellets and for throwing or distributing the pellets over the lawn as it is being mowed. The pressure applied to the grass clippings is adjusted to be sufficient for the extrusion, but insufficient for squeezing the natural juices out of the grass clippings. To avoid clogging and positive extrusion at all times during the operation, the compression rollers are preferably driven positively by a double drive system for rotation about a vertical and horizontal axis.

摘要： The four-wheel lawn tractor has a rear mounted detachable grass catcher bag to collect the grass clippings conveyed by a discharge conduit emerging and extending upwardly from the worm type mower housing. The discharge conduit is left open at the bottom side whereby its length, slope and turn and also the blower capacity are designed according to flow codes that will permit grass clippings to be conveyed uninterruptedly and turbulence-free through to the outlet end of the discharge conduit. The outlet end of the discharge conduit is disposed below a swivel shaft of a catcher hood covering the top of a catcher bag in its horizontal swivel position. If the catcher bag is removed, the catcher hood may be swung in a vertical hanging position transverse to the outlet end of the discharge conduit permitting a mulching operation of the lawn tractor in which the clippings drop down on the lawn surface.
摘要翻译：四轮草坪拖拉机具有后装安装的可拆卸的草地捕捉袋，用于收集由排出管道输送并从蜗杆式割草机壳体向上延伸的草屑。排放管道在底部保持打开，其长度，坡度和转动以及鼓风机容量根据流程编程设计，这将允许草屑不间断地输送并且无湍流通过排放管道的出口端。排放导管的出口端设置在捕获器罩的旋转轴的下面，覆盖捕获器袋的水平旋转位置的顶部。如果抓地袋被移除，捕获器罩可以垂直于排放管道出口端的垂直悬挂位置摆动，允许草坪拖拉机的覆盖操作，其中剪切物在草坪表面上下降。

摘要： A clearing blade, as an attachment for a garden tractor or the like, is constructed as a double-walled construction thereby forming a box-like spreading funnel (5) between the wall members so that simultaneously with or after clearing snow, salt or other granular material may be spread by the same implement used for the clearing. Due to the rigid box-structure of the blade a sufficient strength is obtained even by materials of lesser strength than expensive, fracture resistant steels. Hence, such materials of lesser strength, e.g., synthetic materials, may be used for manufacturing the present blade by an injection molding or die-casting method.
摘要翻译：作为花园拖拉机等的附件的清理叶片被构造为双壁结构，从而在壁构件之间形成盒状扩散漏斗（5），从而在清除雪，盐或其它物体后同时或之后粒状材料可能被用于清除的相同工具传播。由于刀片的刚性箱体结构，即使是具有比昂贵的抗断裂钢的强度低的材料也能获得足够的强度。因此，这种具有较小强度的材料，例如合成材料，可用于通过注塑或压铸方法制造本发明的刀片。
