Section4 : Operation Tilling Tips & Techniques Clearing the tines The tines have a self - clearing action which helps to eliminate most tangling of debris . However , occasionally dry grass , stringy stalks or tough vines may becometangled . Followtheseprocedures to help avoid tanglingandto clear the tines , if necessary . Beforeclearing the tines by hand , stop the engine , allow all moving parts to stop and disconnect the spark plug wire . Failure to follow this warning couldresult in personal injury .
