What are two important steps to ensure mower safety during maintenance?

• A. Start the mower to test blades after maintenance.
• B. Disable safety switches only while testing.
• C. Disconnect power source before work and keep blades sharp and properly attached; wear protective gear.
• D. Remove blades and leave dangerous parts exposed to air.

Answer: (C)

Preventing accidental startup while you work and keeping the blade system in proper, safe condition are the crucial safety actions during mower maintenance. Disconnecting the power source before any maintenance stops the mower from starting unexpectedly, so your hands, clothing, and any tools won’t be drawn into moving parts. This is the fundamental safeguard that makes all other maintenance possible without risk of severe injury.

Keeping blades sharp and properly attached reduces the chance of slippage, imbalance, or blade failure when you reassemble and test the mower later. A secure, balanced blade stays attached and spins true, while sharp blades require less force and heat, making the work safer and easier. Wearing protective gear adds a layer of protection against cuts, flying debris, and noise, helping you stay safe throughout the procedure.

Avoid starting the mower to test blades during maintenance, don’t disable safety switches for testing, and don’t leave dangerous parts exposed. These practices compromise safety and can lead to serious injuries.
