The short answer: To keep your EGO LM2135SP running smoothly for years, clean the deck after each use, check the blade monthly, store the battery at 50% charge in a cool place, and inspect the underside for grass buildup. Regular maintenance prevents rust, battery degradation, and poor cutting performance.
The EGO LM2135SP is a cordless electric mower, but it still faces the same enemies as gas mowers: grass clippings, dirt, and moisture. If left on the deck, clippings can trap moisture and lead to rust, which weakens the metal over time. Grass buildup under the deck can also reduce airflow, making the motor work harder and decreasing battery efficiency. A clean mower not only lasts longer but also cuts better, leaving a neat lawn instead of torn grass.
Beyond the deck, the battery and motor are sensitive to heat and moisture. Maintaining them properly means you won’t have to replace parts prematurely, saving you money and hassle. Plus, a well-maintained mower retains its value if you ever decide to upgrade.
Here’s a simple routine you can follow after every mowing session, or at least every few uses:
1. Safety first: Always remove the battery before cleaning. This prevents accidental starts and protects you from electrical hazards.
2. Brush off loose debris: Use a stiff brush or a plastic scraper to remove grass clippings and mud from the deck, wheels, and under the mower. Avoid using a metal scraper on painted surfaces to prevent scratches.
3. Rinse with water: If you have a hose, you can rinse the underside of the deck. Tilt the mower back (with the battery removed) and spray with a gentle stream. Be careful to avoid the motor and electrical components. Many users also use a hose attachment that connects to the deck’s wash port, if your model has one, but for the LM2135SP, a simple rinse works. Let it dry completely before storing.
4. Clean the battery and contacts: Wipe the battery with a dry cloth to remove dust or grass. Check the metal contacts on both the battery and the mower for corrosion. If you see any, gently clean with a dry cloth or a pencil eraser.
5. Wipe down the body: Use a damp cloth to wipe the top of the mower, the handle, and the grass bag. This keeps the mower looking new and prevents dirt from working its way into the controls.
The blade is the heart of your mower. A dull blade tears grass, making it more susceptible to disease. It also forces the motor to work harder, draining the battery faster. You should inspect the blade every month during the mowing season.
Sharpening: You can sharpen the blade yourself with a file or a bench grinder, or take it to a professional. Remove the blade by tilting the mower and using a wrench to loosen the bolt (usually 18mm). Note the orientation so you can reinstall it correctly. If you sharpen, wear gloves and safety glasses. Balance the blade after sharpening by hanging it on a nail; if one side dips, sharpen that side a bit more.
Replacement: If the blade has deep nicks, cracks, or is bent, replace it. A new blade is a mid-range purchase, and you can find them online or at home improvement stores. Always use original EGO blades or compatible ones recommended by the manufacturer.
When reinstalling, torque the bolt to the manufacturer’s spec (about 30-40 ft-lbs) to ensure it doesn’t come loose.
The battery is the most expensive part of your EGO mower, so proper care is essential. Here are key tips:
Storage: Store the battery at around 50% charge in a cool, dry place. Extreme temperatures, especially heat, degrade lithium-ion cells. Avoid leaving it in a hot garage or attached to the charger after it’s fully charged.
Charging: Use only the EGO charger that came with the mower. Don’t charge overnight; unplug once fully charged. If you’re not using the mower for a month or more, recharge the battery to 50% every 3 months.
Cleaning: Wipe the battery terminals with a dry cloth to prevent corrosion. Also, keep the battery out of rain and moisture.
At the end of the mowing season, do a thorough cleaning and inspection.
End-of-Season Steps: Clean the mower as described, sharpen or replace the blade, and lubricate any moving parts like the wheel height adjustment (use a light oil like WD-40). Remove the battery and store it separately at 50% charge. Store the mower in a dry place, ideally off the ground to avoid moisture.
Common Issues: If the mower doesn’t start, check the battery charge and connection. If it cuts poorly, check the blade for dullness or damage. If the motor runs but the mower doesn’t move, check the self-propelled drive system for grass buildup. Most issues are solved with simple cleaning.

Can I use a pressure washer to clean my EGO mower? No, pressure washers can force water into the motor and electrical components, causing damage. Stick to a gentle hose spray or a damp cloth.
How often should I sharpen the blade? Sharpen every 20 to 25 hours of use or at least once a month during the season, depending on your lawn conditions. If you notice ragged grass tips, it’s time to sharpen.
What is the best way to store the battery in winter? Store it at about 50% charge in a cool, dry place, ideally between 40°F and 80°F. Check it every few months and recharge if it drops below 30%.
Following these simple steps will keep your EGO LM2135SP performing like new for years. Regular care not only protects your investment but also ensures a clean, healthy lawn every time you mow.
