S1: Do the blades have a rust-resistant design? Specifically, for environments like mine with a moist lawn, does it have any anti-corrosion measures?

Answer:
The blades are made from rust-resistant materials and come pre-coated with anti-rust oil. However, if you use the mower regularly in a damp or humid environment—and don’t replace the blades—their sharpness and cutting performance may gradually decline over time.

To keep your mower running at its best, we recommend replacing the blades every 1–2 months.
