摘要： A grass or vegetation cutting blade is provided, which includes multiple cutting edges, including a leading cutting edge positioned below a trailing cutting edge. An upturned foil is provided behind the leading edge, such that grass initially cut by the leading edge is directed upwardly by the foil toward the trailing edge, to be cut in midair. An inturned spur is provided, which provides inward air and clipping flow toward the rotational axis of the blade. The blade is contemplated for use in conventional side- or rear-discharging housings, as well as mulching or recycling housings. The blade is resistant to clogging, and includes power efficient properties.
摘要翻译：提供草或植被切割刀片，其包括多个切割边缘，包括位于后切割边缘下方的前切割刃。在前缘后面设置有上翘的箔片，使得最初被前缘切割的草被箔朝向后缘向上引导，以在空中切割。提供内翻的支线，其向叶片的旋转轴线提供向内的空气和夹持流动。叶片被设计用于常规的侧面或后排出壳体以及覆盖或回收壳体。刀片耐堵塞，并包括功率效率特性。

摘要： A lockout feature for preventing a lawn mower from going into reverse unless the lawn mower blade is first disengaged, while allowing the lawn mower cutting blade to be reengaged upon being placed in reverse, the latch nevertheless allowing the lawn mower to be moved out of reverse without disengaging said lawn mower blade. An override feature is also allowed by use of a separate override control to allow the user to override the reverse lock out latch in order to go from forward or neutral into reverse without disengaging the cutting blade.
摘要翻译：一种锁定功能，用于防止草坪割草机首先脱开，除非割草机叶片首先脱开，同时允许割草机切割刀片被倒置时被重新接合，然而，闩锁仍允许割草机移出反向而不会脱离所述割草机叶片。还可以通过使用单独的覆盖控制来允许用户覆盖反向锁定闩锁，以便在不使切割刀片脱离的情况下从正向或中立转向反向。

摘要： A height of cut adjustment system for use with a walk behind mower. The height of cut adjustment system includes a single drive motor that is operable in a first direction and a second direction. The single drive motor is connected to a linkage assembly that supports the four wheels of the walk behind mower relative to the mower deck. When the single drive motor is operated in a first direction, the mower height of cut increases and when the drive motor is operated in the second direction, the height of cut is decreased. The height of cut adjustment system includes a height of cut indicator system that visually indicates the relative position of the wheels relative to the mower deck. The height of cut indicator system includes one or more position indicators that can be selectively positioned to visually indicate the desired height of cut for the mower.
