摘要： A lawnmower uses thin, replaceable blades with a hardened cutting edge. Such blades are held by blade holding elements in a horizontally rotating mower blade assembly. The blade assembly and blade assembly housing are configured in a specialized cross-flow mower assembly to reduce grass leave tip damage, increase cut quality and overall aesthetic appeal, while consuming less power and providing a reduced environmental impact.

摘要： An operator presence control assembly for a walk-behind greens mower includes a handle supported on a frame of the walk-behind greens mower, a ribbon switch on the outer perimeter of the handle, and a circuit including the ribbon switch. The circuit is completed by applying a threshold pressure to the ribbon switch, and a device selectively energizeable via the circuit in accordance with the threshold pressure applied to the ribbon switch. As the user of the greens mower grips the handle, the ribbon switch completes a circuit to energize a switch to engage an electromagnetic clutch.

摘要： The present invention provides for an automated clip control device for maintaining a predetermined clip at varying ground speeds, heights of cut, and other changed conditions. The reel speed of the mower 10 is controlled based upon a feed-back control loop, using as input the ground speed of the mower 10, the actual speed of the reel 48, 50, and 52, the number of blades on the reel, and height of cut, among other factors. A microprocessor 102 uses control process equations to determine the duration of an output pulse width modulated signal which is provided to a valve 702, 706 controlling hydraulic fluid flow to the reel motor 71-75. The target value of the reel speed is determined by reading the desired height of cut value and the number of blades per reel, and then going to a look-up table which contains optimized "linear distance traveled per time grass is cut" values. Once the appropriate look-up table target value is found, the target reel speed is determined by finding the product of the number of blades on the reel times the target clip times the ground speed times a constant (to correct for units).
摘要翻译： 本发明提供一种自动剪辑控制装置，用于在变化的地面速度，切割高度和其它改变的条件下保持预定的剪辑。 基于反馈控制回路控制割草机10的卷轴速度，使用割草机10的地面速度，卷轴48,50和52的实际速度，卷轴上的叶片数量， 和切割高度等因素。 微处理器102使用控制过程方程来确定输出脉宽调制信号的持续时间，该信号被提供给控制到卷轴电动机71-75的液压流体的阀702,706。 卷轴速度的目标值通过读取所需的切割值的高度和每个卷轴的叶片数量来确定，然后进入包含优化的“每次切割时的线性距离被切割”的查找表。 一旦找到了适当的查找表目标值，则通过找到卷轴上的叶片数量乘以目标剪辑乘以地面速度乘以常数（以校正单位）来确定目标卷轴速度。

摘要： In a lawn and garden implement, a starting system is provided therefor which prevents accidental energization of the implement, and which also provides for automatic deenergization of the implement upon release thereof by the operator. The starting system includes an actuator lever engaging a switch actuator to rotate a removable key inserted within a rotary operated switch to open and close the implement's circuitry. Lockout means are provided which engage the switch actuator and which must be disengaged therefrom to permit actuator rotation. The component parts of the present invention all cooperate sequentially to provide a starting system which will not energize the implement unless the operator consciously follows the proper starting sequence.
