Proper storage of your John Deere Z930M is crucial for maintaining its performance and longevity. Ignoring the proper storage protocols can lead to costly repairs and a shortened lifespan for your valuable equipment. Before storing your mower for the off-season, or for any extended period of inactivity, a thorough preparation process is essential. This involves a meticulous inspection, cleaning, and preventative maintenance to ensure it starts readily and operates optimally when you're ready to use it again. Start by thoroughly cleaning the entire mower, removing any accumulated grass clippings, dirt, and debris. A clean machine is easier to inspect for potential problems and prevents the build-up of corrosive materials that could cause damage during storage.
After cleaning, carefully inspect all components for signs of wear, damage, or potential issues. Check the belts for cracks or fraying, inspect the blades for sharpness and balance, and examine the tires for proper inflation and damage. Pay close attention to the engine, looking for any leaks or signs of corrosion. Addressing these issues before storage can save you time and money down the road.

Making detailed notes will help ensure you don't forget any critical maintenance tasks when you're ready to start the mower again.
One of the most critical steps in preparing your Z930M for storage is addressing the fuel system. Gasoline left sitting for extended periods can degrade, leading to the formation of gum and varnish deposits that can clog fuel lines, carburetors, and injectors. This can result in hard starting, poor performance, and potentially costly repairs. To prevent these problems, you have two primary options: completely draining the fuel system or adding a fuel stabilizer to the gasoline.
If you choose to drain the fuel system, carefully siphon out all the gasoline from the fuel tank using a siphon pump. Once the tank is empty, start the engine and let it run until it stalls due to lack of fuel. This will ensure that the fuel lines and carburetor are also emptied of gasoline. However, for added protection, especially if you're storing the mower for several months, adding a fuel stabilizer is highly recommended. Fuel stabilizers are designed to prevent the degradation of gasoline and protect the fuel system from corrosion and deposit formation. Add the stabilizer to the fuel tank according to the manufacturer's instructions and run the engine for a few minutes to allow the stabilized fuel to circulate throughout the fuel system.
The battery is another crucial component that requires special attention during storage. Leaving a battery unattended for an extended period can lead to sulfation, a process where lead sulfate crystals form on the battery plates, reducing its capacity and lifespan. In severe cases, sulfation can render the battery completely unusable. To prevent sulfation and ensure your battery is ready to go when you need it, several steps can be taken.
First, disconnect the battery cables from the battery terminals. This will prevent any parasitic drain on the battery, which can occur even when the mower is not in use. Clean the battery terminals and cable ends with a wire brush to remove any corrosion. Apply a thin coat of dielectric grease to the terminals to protect them from future corrosion. Ideally, store the battery in a cool, dry place, away from direct sunlight and extreme temperatures. Consider using a battery maintainer or trickle charger to keep the battery fully charged during storage. These devices provide a low, constant current that prevents sulfation and keeps the battery in optimal condition.
Once you've completed the mechanical preparations, it's time to protect the mower from the elements during storage. Covering the mower will shield it from dust, dirt, moisture, and sunlight, all of which can contribute to corrosion and deterioration. Choose a durable, waterproof cover that is specifically designed for outdoor equipment or lawn mowers. Ensure the cover fits snugly and securely to prevent it from blowing off in windy conditions.
Ideally, store the mower in a garage, shed, or other sheltered location. If you must store it outdoors, choose a location that is protected from direct sunlight and rain. Consider placing the mower on a pallet or blocks to elevate it off the ground, preventing moisture from wicking up and causing corrosion. Regularly inspect the mower during storage to ensure the cover is still in place and that there are no signs of damage or leaks. By following these steps, you can ensure your John Deere Z930M remains in excellent condition and is ready for reliable performance when spring arrives.
