Cleaning the Deck:
Cleaning the mower deck prevents grass buildup and rust, enhancing airflow and cutting performance. Grass clippings can accumulate and block cutting effectiveness. After each use, it should be wiped down or hosed off. This practice can prolong the mower’s lifespan significantly. -
Tire Checks and Maintenance:
Tire checks and maintenance ensure proper tire pressure and tread condition. Under-inflated tires can affect maneuverability and cause uneven cutting. Regularly inspecting tire pressure helps maintain optimal performance and safety while mowing. -
Storage Recommendations:
Proper storage recommendations entail keeping the mower in a dry, sheltered area to prevent corrosion. During winter, proper storage includes draining fuel and removing the battery. This prevents battery damage and degradation of components.
