Abstract
A safety mechanism for a turf aerator having a frame and an engine with a governor that generally prevents the turf aerator from operating at full power unless the safety mechanism is engaged. A blocking mechanism and a manual actuation device are mounted to the frame. The manual actuation device is in mechanical communication with the blocking mechanism. The blocking mechanism urges the governor toward a loaded position and the engine operates at a generally low power when the governor is in the loaded position.
