ABSTRACT:
A walk behind lawn mower operating system. The system comprises a handlebar onto which control bails with ends are pivotally attached, with the control bails being operatively connected to propulsion and blade brake systems, respectively. The control bails are arranged on the handlebar such that they pivot away from the handlebar in opposite directions. The control bails' cross-sectional dimensions are essentially identical. Each of the control bail's movement is limited by a bail pivot stop. Each bail pivot stop is removably attached to a control bail end so that it pivots with the control bail and restricts the pivoting movement by impinging upon the handlebar with an integrally formed stop. In the preferred embodiment, where the control bails pivot away from the handlebar in opposite directions, the control bail stops are located at either side of the handlebar.
