2. Deterioration of Components

Moisture can also damage other components in your lawn mower, leading to a gradual deterioration of the machine.

Plastic and Rubber Components

  • Plastic and rubber parts: Rain and humidity can cause plastic and rubber components to become brittle and crack over time.
  • Fuel lines and hoses: Fuel lines and hoses can crack and leak, leading to fuel spills and engine problems.

3. Bearing and Gear Damage

The bearings and gears in your lawn mower are crucial for its smooth operation. Water ingress can lead to corrosion and wear on these components, affecting the machine’s overall performance.

Why Bearings and Gears are Vulnerable

  • Friction and wear: Bearings and gears experience significant friction during operation. When exposed to moisture, this friction can accelerate wear and tear, leading to premature failure.
  • Corrosion: Moisture can cause corrosion on the bearing surfaces and gear teeth, hindering smooth movement and potentially causing seizing.
