摘要： A walk-behind implement, e.g., lawn mower, having a handle assembly, and a handle assembly release apparatus for use with such an implement. The release apparatus, in one embodiment, may permit unlocking of the handle assembly from a first operating position relative to a housing of the implement. Once unlocked, the handle assembly may be moved, e.g., pivoted, to a second storage position. In one embodiment, the release apparatus may include a lever member that may be actuated by the application of a force applied by an operator's foot.

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 is 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 “wheelies” 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会受到近似零半径期间产生的离心力的影响，从而使割草机能够以更高的速度转动。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 zero-turning radius self-propelled power lawn mower includes a standing platform structure for supporting a standing operator during mower operation. The mower has a combination parking brake and pump lockout structure which, when actuated, simultaneously applies a braking force to rear drive wheels and prevents hydro pumps from being moved from their neutral positions. The mower also includes a biasing system for automatically returning hand control levers to their neutral positions when they are not being manipulated by an operator. Unique cutter deck structure, caster structure, grass catcher structure, and steering control levers are also provided.

摘要： An operator control system for a self-propelled vehicle such as a lawn mower, wherein the control system includes two opposing and preferably upwardly extending and converging hand grips each having a corresponding drive control lever associated therewith. Each drive control lever may have at least a portion that is parallel to a grip axis of its respective hand grip. Further, each drive control lever may have a pivot axis that is substantially parallel to the corresponding grip axis such that the drive control lever remains substantially parallel to its respective hand grip throughout its travel. A neutral lock is provided to permit locking of each drive control lever in at least one position, e.g., a neutral position. Secondary levers such as operator presence control (OPC) levers may also be included. An OPC lever is associated with each hand grip.

摘要： Vegetation trimmers and methods for reconfiguring a trimmer are provided. A coupling mechanism permits reconfiguration of the trimmer between a first, e.g., trimming, configuration and a second, e.g., edging, configuration. The coupling mechanism may, in one embodiment, be used to couple a handle assembly with an extension tube. By rotating the handle assembly relative to the extension tube, the trimmer is moved between the trimming and edging configurations. In one embodiment, the mechanism may apply a biasing force to the handle assembly relative to the extension tube. The biasing force tends to bias the trimmer towards and retain the trimmer in the desired configuration. To switch the trimmer between configurations, the operator may impart a twisting force between the handle assembly and the extension tube where the twisting force is sufficient to overcome the biasing force. Optionally, a longitudinal force may also be applied before or during the application of the twisting force.
摘要翻译：提供植被修剪器和重新配置修剪器的方法。联接机构允许修剪器在第一，例如修剪，配置和第二，例如边缘配置之间重新配置。在一个实施例中，联接机构可以用于将手柄组件与延伸管连接。通过相对于延伸管旋转手柄组件，修剪器在修剪和边缘配置之间移动。在一个实施例中，机构可以相对于延伸管施加偏压力到手柄组件。偏置力倾向于使修剪器偏置并将修剪器保持在期望的构造。为了在配置之间切换修剪器，操作者可以在手柄组件和延伸管之间施加扭转力，其中扭转力足以克服偏压力。任选地，也可以在施加扭转力之前或期间施加纵向力。

摘要： An easy grip tool (10) comprising a implement head (12). An elongated rigid handle (14) has upper and lower offset handgrips (16), (18) formed therein. A structure (20) is for attaching a bottom end of the elongated rigid handle (14) to a top end of the implement head (12) in a removable manner. The elongated rigid handle (14) can be adjusted to the implement head (12), so that a left handed and a right handed person (22) can grip the upper and lower offset handgrips (16), (18) to comfortably sweep the implement head (12) along the ground (24). In a second embodiment being an easy grip tool (10a), the elongated rigid handle (14) is substituted with an elongated rigid handle (14a) having a ninety degree offset portion (54) formed near a bottom end. The elongated rigid handle (14a) can be adjusted to the implement head (12), so that the left handed and a right handed person (22), can grip the elongated rigid handle (14a) to comfortably sweep the implement head (12) along the ground (24).
