ABSTRACT:
A power lawn mower having a transversely arranged tubular grip for manual control rockable forwardly from a reference position to adjust a power control member. The grip is of oval cross section dimensioned to fit the grasp of the operator's hands. When the grip is in reference position the long dimension of the oval is angled rearwardly and downwardly so as to be substantially parallel to the operator's palms in a natural grasping position, so that the operator can sense by the orientation of his hands the neutral, or starting, position of the power control member and, upon forward rocking, the degree of departure from neutral position. A safety latch is provided for securely latching the grip in its reference position. A latch-releasing trigger on the grip is positioned to be manually engageable by at least one hand of the operator incident to grasping the grip for releasing the latch and thereby releasing the grip for forward rocking movement. The grip is coupled to the power control member by a cable having a return spring for restoring the grip to latched reference position when the grip is manually released, providing a so-called "dead man" control.
