Abstract: 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.

Abstract: A grass catcher for attachment to a power mower. In certain embodiments, the grass catcher is mounted to a self-propelled power mower so that the catcher is pivotable about two substantially perpendicular axes simultaneously.
