It’s essential to winterize zero turn mower for storage in winter. Proper winterization ensures that your mower remains in excellent condition and is ready for use when spring arrives. This article will guide you through the steps to winterize your zero turn mower, covering everything from cleaning and maintenance to storage tips。
Preparation and Cleaning
Thorough Cleaning
Exterior Cleaning
Begin by thoroughly cleaning the exterior of your zero turn mower. Use a hose to remove dirt, grass clippings, and debris from the mower deck, wheels, and body. For stubborn grime, use a brush and soapy water. Cleaning the mower prevents rust and corrosion during storage.
Under the Deck
Raise the mower deck and clean underneath to remove any grass buildup and debris. Grass clippings left under the deck can retain moisture and cause rust. Use a scraper or putty knife to remove any stuck-on grass and dirt.
Engine Cleaning
Air Filter
Remove the air filter and clean it according to the manufacturer’s instructions. If the air filter is excessively dirty or damaged, replace it with a new one. A clean air filter ensures that the engine runs efficiently and prevents dust and debris from entering the engine.
Engine Cooling Fins
Check the engine cooling fins for any dirt or debris. Use compressed air or a soft brush to clean the fins. Clogged cooling fins can cause the engine to overheat, leading to potential damage.

Maintenance Tasks-winterize zero turn mower
Oil Change
Draining the Oil
Changing the oil is a crucial step in winterizing your zero turn mower. Start by running the engine for a few minutes to warm up the oil, making it easier to drain. Turn off the engine, remove the oil drain plug, and let the old oil drain into a container. Dispose of the used oil properly according to local regulations.
Replacing the Oil Filter
While the oil is draining, replace the oil filter. Remove the old filter and install a new one, following the manufacturer’s instructions. A new oil filter ensures that the engine remains clean and lubricated.
Adding Fresh Oil
Once the old oil has drained completely, replace the drain plug and add fresh oil. Use the type and amount of oil recommended by the manufacturer. Check the oil level with the dipstick to ensure it is at the correct level.
Fuel System Maintenance-winterize zero turn mower
Adding Fuel Stabilizer
To prevent the fuel from deteriorating over the winter, add a fuel stabilizer to the gas tank. Follow the instructions on the stabilizer bottle for the correct amount to add. Run the engine for a few minutes to circulate the stabilizer throughout the fuel system.
Draining the Carburetor
If your zero turn mower has a carburetor, it’s a good idea to drain it to prevent fuel from gumming up the carburetor parts. Consult your owner’s manual for instructions on how to drain the carburetor.
Battery Care-winterize zero turn mower
Removing the Battery
Remove the battery from the mower to prevent it from discharging over the winter. Disconnect the negative (black) cable first, followed by the positive (red) cable. Clean the battery terminals with a wire brush to remove any corrosion.
Storing the Battery
Store the battery in a cool, dry place where it won’t freeze. Place it on a wooden surface rather than directly on concrete, as concrete can cause the battery to discharge. Use a battery maintainer to keep the battery charged over the winter.
Blade Maintenance-winterize zero turn mower
Sharpening the Blades
Remove the mower blades and sharpen them if necessary. Sharp blades ensure a clean cut and reduce the strain on the engine. Use a file or grinder to sharpen the blades, following the manufacturer’s guidelines for the correct angle.
Balancing the Blades
After sharpening, check the balance of the blades. An unbalanced blade can cause vibration and damage to the mower. Use a blade balancer to ensure the blades are balanced correctly.
Storage Tips-winterize zero turn mower
Choosing the Right Storage Location
Indoor Storage
Store your zero turn mower in a dry, sheltered location, such as a garage or shed. Indoor storage protects the mower from the elements and reduces the risk of rust and corrosion.
Outdoor Storage
If indoor storage is not possible, use a heavy-duty, weatherproof cover to protect the mower from rain, snow, and ice. Ensure the cover fits snugly and secures it to prevent it from blowing off in strong winds.
Final Steps
Disconnecting Spark Plug
Disconnect the spark plug to prevent accidental starting. Remove the spark plug wire and clean the area around the spark plug to remove any dirt or debris.
Lubricating Moving Parts
Apply a light coat of oil or a suitable lubricant to moving parts such as the steering levers, wheels, and mower deck height adjustment mechanisms. Lubrication prevents rust and ensures smooth operation when you use the mower in the spring.
