摘要： A self-propelled power lawn mower for operation by an operator. The operator can operate the mower while standing on a foot platform, or alternatively when sitting down on a selectively deployable seat. Thus, the mower includes both sitting and standing modes. In certain embodiments, at least a portion of the foot platform is located between first and second rear drive wheels. The rear drive wheels are independently driveable in both forward and reverse directions at variable speeds so as to allow for approximate zero radius turning of the mower about a vertical turning axis. The foot platform is positioned near this vertical axis so that the operator when standing may be substantially unaffected by centrifugal force created during approximate zero radius turning of the mower.

摘要翻译： 一台自行动力割草机，由操作人员操作。 操作者可以在站在脚踏平台上时操作割草机，或者当坐在可选择展开的座椅上时。 因此，割草机包括坐姿和站立模式。 在某些实施例中，足平台的至少一部分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，以便允许割草机围绕垂直转动轴线进行近似的零半径转动。 脚踏平台位于该垂直轴线附近，使得操作者站立时可基本上不受割草机近似零半径转动期间产生的离心力的影响。
