Operate the engine for a few minutes after adding the stabilizer to ensure it circulates throughout the fuel system. This simple step can save you significant headaches when you try to start the machine after storage.
Finally, address any outstanding maintenance issues before storing the 1445. This could include replacing worn belts, sharpening mower blades, or repairing any leaks. By taking care of these tasks before storage, you'll avoid having to deal with them when you need the machine again. A proactive approach to maintenance will also help prevent minor problems from escalating into more serious and costly repairs over time. Make a list of any maintenance items that you didn't have time to complete before storage, so you can address them promptly when you retrieve the machine.
Choosing the right storage location is paramount to protecting your John Deere 1445 from the elements. Ideally, store the machine indoors in a dry, well-ventilated space, such as a garage or shed. This will shield it from rain, snow, sun, and temperature fluctuations, all of which can contribute to corrosion and deterioration. If indoor storage isn't an option, cover the machine with a waterproof tarp or cover. Make sure the cover is breathable to prevent moisture from trapping underneath, which can actually promote rust. Secure the cover tightly to prevent it from blowing away in windy conditions.
Disconnect the battery cables to prevent battery drain during storage. Clean the battery terminals with a wire brush and apply a thin coat of petroleum jelly to prevent corrosion. Store the battery in a cool, dry place, and consider using a battery maintainer to keep it charged throughout the storage period. A fully charged battery is less likely to freeze and suffer damage in cold weather. You can purchase battery maintainers at most auto parts stores. These devices automatically cycle the battery between charging and float modes, preventing overcharging and keeping the battery in optimal condition.
If possible, raise the mower deck off the ground to prevent the tires from developing flat spots. You can do this by placing wood blocks under the deck. Alternatively, inflate the tires to the maximum recommended pressure to help maintain their shape. Periodically check the tire pressure throughout the storage period and add air as needed. Consider lubricating all grease fittings on the machine to protect them from corrosion. Apply grease to the fittings on the mower deck spindles, wheel bearings, and other moving parts. This will help ensure smooth operation when you retrieve the machine from storage.
Before starting the engine, give the machine a thorough inspection. Check all fluid levels again, including engine oil, coolant, hydraulic fluid, and fuel. Make sure there are no leaks or signs of damage. Reconnect the battery cables, ensuring they are securely fastened and free of corrosion. If you used a battery maintainer, disconnect it before starting the engine. Check the air filter to ensure it's clean and free of debris. A dirty air filter can restrict airflow and reduce engine performance.
If you drained the fuel tank before storage, add fresh gasoline. Start the engine and let it idle for a few minutes to allow the fuel to circulate. Monitor the engine for any unusual noises or vibrations. If the engine doesn't start readily, check the spark plug to ensure it's clean and in good condition. You may need to prime the carburetor by pumping the fuel bulb a few times. Once the engine is running smoothly, engage the mower deck and check for any vibrations or unusual noises. Inspect the mower blades to ensure they are sharp and properly balanced.
Before using the machine for extended periods, take it for a short test run. Check the brakes, steering, and other controls to ensure they are functioning properly. If you notice any problems, address them immediately. Perform any necessary maintenance, such as changing the engine oil and filter, lubricating grease fittings, and sharpening mower blades. With proper preparation and maintenance, your John Deere 1445 will be ready to tackle any lawn care task after storage.
