Abstract
A device for engaging and disengaging the driving mechanism of an automatic slide gate. The device uses a series of two levers to develop a substantial mechanical advantage in the operation of a dog clutch. An actuating lever is positioned so that it may be operated by the user's foot, eliminating the need for any auxilliary levers or tools.
