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.

Abstract: A turf aerator is provided with three aligned aerator shafts having aerator devices mounted thereon. The innermost shaft is mounted in a frame for free-willing operation and the two outer shafts are each connected to a motor through selectively controlled hydraulic pumps which in turn are connected to hydraulic motors for driving the outermost shafts selectively or simultaneously with the innermost shaft being mounted for free-willing operation.

Abstract: A turf aerator is provided with two separate shafts, each having a plurality of tines mounted thereon for aerating the turf. Each shaft is selectively connected to an output shaft of a motor mounted on the frame of the aerator by two separate drive trains, each having a clutch arrangement therein. A pair of control levers are mounted on a handle assembly for operating the clutches in each drive train. Thus either or both of the tine carrying shafts may be rotated to facilitate a turning operation of the aerator or facilitating the operation of the aerator while traversing a sloping surface.
