Operating Instructions STARTING THE MACHINE CAUTION ALWAYS disengage the PTO clutch and put the FSC in the NEUTRAL-PARK position before starting the engine.

Adjust ground speed to properly position tines as shown.
Operating Instructions RECOMMENDATIONS FOR AERATING STOPPING THE MACHINE For best results the ground must have a sufficient amount of moisture to allow the tines maximum penetration. 1. Disengage the PTO clutch. 2. IMPORTANT: Operate the engine at full speed when operating the aerator, to allow the engine to produce full horsepower and to increase efficiency of the engine cooling system.
