A full service for a zero-turn at Harrington’s entails a complete evaluation of the unit. We go through the unit’s filters such as the oil, air, and fuel replacing them if they do not meet our standards. We install new spark plugs, put fresh oil and fuel in the unit. We will grease the unit, clean, and set the tire pressure. We check the battery to ensure it holds a load, we clean it, and spray the battery with protectant. We examine the charging system to ensure it works properly. We check the hydro pumps and belts on the unit. If the unit has a deck we will sharpen the blades, grease, clean and balance the deck. We test the unit before it leaves our shop ensuring that it runs properly.
