<p>A walk behind powered apparatus (10) having a mobile structure (12), a work implement drive system (38) coupled to the mobile structure (12), a power device (32) driving the work implement (18), and a handle structure (40) coupled to the mobile structure (12). The handle structure (40) includes a cam slot (76) having a first portion (78) and a second portion (80). The second portion (80) is orthogonal to the first portion (78). A bail member (64) is pivotally coupled to the handle structure (40) and includes a pin (74) extending therefrom. The pin (74) cammingly engaging the slot (76) such that when the bail member (64) is in a first position the pin (74) is disposed in the first portion (78) of the slot (76) and when the bail member (64) is in a second position the pin (74) is disposed in the second portion (80) of the slot (76). A switch device is coupled to the work implement drive system (38) and selectively actuates the work implement drive system (38) in response to the movement of the bail member (64) between the first position and the second position. A biasing member (66) biases the bail member (64) into the first position to prevent inadvertent actuation of the switch device. <IMAGE></p> |
