Smart Storage Practices
How you store your riding mower during the off-season or periods of disuse is critical for preventing deterioration and extending its mower service life.
- Cleanliness is Key: A thorough cleaning after the last mow is essential. Remove all grass clippings, dirt, and debris from the deck, engine, and chassis. This prevents corrosion and insect nesting.
- Fuel Stabilization:
- Option 1 (Run Dry): The best method is to run the mower until it runs out of fuel. This empties the carburetor, preventing fuel system gumming.
- Option 2 (Fuel Stabilizer): If running dry isn’t feasible, fill the fuel tank about 90% full and add a quality fuel stabilizer. Run the engine for a few minutes to ensure the stabilized fuel circulates through the fuel system and carburetor.
- Battery Care: Remove the battery and store it in a cool, dry place. Connect it to a trickle charger periodically to maintain its charge. Alternatively, leave it in the mower and connect it to a smart charger designed for seasonal storage.
- Lubrication: Re-grease all grease points before storage. This helps displace moisture and keeps parts moving freely.
- Tire Protection: Over time, tires can develop flat spots if the mower sits in one position. If possible, lift the mower slightly off the ground using jack stands to take the weight off the tires. If this isn’t possible, at least inflate the tires to the higher end of the recommended range.
- Covering: Use a breathable mower cover to protect it from dust and scratches. Avoid plastic tarps that can trap moisture and lead to condensation and rust.
- Ideal Storage Location: A climate-controlled garage or shed is the best place. Avoid damp basements or areas prone to extreme temperature fluctuations.
Component Care and Replacement
Timely replacement of worn parts is crucial for preventing cascading failures.
- Blade Sharpening and Balancing: Regularly sharpen mower blades. Dull blades tear grass, making it susceptible to disease, and force the engine to work harder. Balanced blades prevent excessive vibration, which can loosen fasteners and damage bearings over time.
- Air Filter: A clogged air filter restricts airflow to the engine, reducing power and fuel efficiency, and can even lead to engine damage. Replace or clean it according to the maintenance schedule.
- Fuel Filter: A dirty fuel filter can starve the engine of fuel, causing sputtering and loss of power. Replace it annually or as recommended.
- Spark Plug: A fouled or worn spark plug can cause hard starting, misfires, and poor fuel economy. Replace it regularly.
- Belts: Inspect drive and deck belts for cracks, fraying, or excessive wear. Replace them before they break, which can lead to more extensive damage.
- Tires: Worn or cracked tires can affect traction and maneuverability. Replace them when tread is low or sidewalls show signs of damage.
- Hydraulic Fluid (for hydrostatic transmissions): If your mower has a hydrostatic transmission, follow the manufacturer’s recommendations for fluid and filter changes. This is critical for the transmission’s longevity.
Typical Riding Mower Replacement Time
While a well-maintained riding mower can last for many years, there comes a point when replacement might be more economical than repair. Several indicators suggest it’s time to consider a new machine:
- Excessive Repair Costs: If the cost of recurring repairs begins to approach the cost of a new, comparable mower, it’s time to re-evaluate.
