摘要： A rotating disc has perforated seed pockets which pick up individual kernels of seed from an air pressurized cavity of a planter housing. Air flowing through the perforated pockets creates a pressure differential which moves a kernel into each pocket as the pocket moves on a circular path upwardly through the cavity. The pocket then moves into axially confronting relation with a flat sealing surface. The flat sealing surface holds the seed in the pocket as the disc rotates further to bring the pocket to the lower part of the housing where the seed falls by gravity into the soil. Each of the circumferentially spaced pockets has an opening in its bottom which is large enough to permit air flow therethrough but smaller than the seed kernels to be planted. The pockets are clam shell shaped with the more gentle slope on the side of the pocket toward the direction of rotation of the disc during planting. The opposite side of the pocket has a steep slope whereby the seed in the pocket is mechanically assisted in its assent from the seed cavity. The seed disc for corn includes a camming groove extending from each pocket which cams corn kernels radially outwardly toward the pocket as it passes upwardly through the seed cavity.

摘要： A grass bagger (13) for a lawn tractor (14). The catcher (13) includes a hood (20) which directs grass clippings into a pair of bag assemblies (40). A grass checker (50), connected to hood (20), is used to check the level of accumulated grass beneath hood (20) to determine when it would be appropriate to empty bag assemblies (40) of their accumulated grass clippings. In order to prevent grass clippings from leaking between bag assemblies (40) and hood (20), and to keep hood (20) from popping open when lawn tractor (14) is driven over rough ground, a pair of latches (70) is included to releasably secure hood (20) to bag assemblies (40).
摘要翻译：用于草坪拖拉机的草包机（13）（14）。抓地器（13）包括将草剪引导到一对袋组件（40）中的罩（20）。连接到发动机罩（20）的草地检查器（50）用于检查发动机罩（20）下面积聚的草地的水平，以确定何时将其累积的草屑的袋子组件（40）清空。为了防止当草坪拖拉机（14）在粗糙地面上被驱动时，草屑在袋组件（40）和罩（20）之间泄漏，并且防止罩（20）打开，一对闩锁（70）是包括以将罩（20）可释放地固定到袋组件（40）。

摘要： A grass catcher for receiving air and grass clippings from a mower cutter deck includes an inlet for admitting air and clippings into the grass catcher, an outlet port for exhausting air out of the grass catcher, and at least two cylindrical, perforate air filters interposed between the inlet and the outlet port. The filters separate grass clippings from the air and permit air to pass through the filters and on to the outlet port. The grass catcher also includes a wave form energy transmitter and a wave form energy receiver positioned in the grass catcher. The transmission of wave form energy between the transmitter and the receiver is interrupted when the level of accumulated grass clippings in the catcher exceeds a predetermined level. The interruption of the transmission triggers an alarm to alert an operator of the mower of the high clipping level within the catcher.
摘要翻译：用于从割草机切割板接收空气和草屑的草地捕捉器包括用于承认空气并将其剪取到草地捕集器中的入口，用于从除草器排出空气的出口和至少两个圆柱形穿孔空气过滤器，入口和出口。过滤器将草屑从空气中分离，并允许空气通过过滤器并进入出口。抓地者还包括定位在捕草器中的波形能量发射器和波形能量接收器。发射机和接收机之间的波形能量的传输在捕获器中累积的草地剪辑超过预定水平时被中断。传输的中断触发警报，以向捕手者中的高削波水平的操作者警告割草机。
