Ariens walk-behind mowers deliver efficient speed and cutting power for everyday landscaping, but routine maintenance is necessary to prevent mowers from stalling or running slowly. Lawn mower tune-ups help you stay ahead of wear and tear and recognize when replacement parts are the safest option.
Proper lubrication protects lawn mower parts from friction and allows smooth movement, so regular oil changes are essential to preserving the engine. Replace oil after a minimum of 50 hours of use to prevent it from breaking down and losing its lubricating properties. You should also change the oil before storing it during colder months. The air filter prevents particles from flooding the engine. Your mower may contain a single-use filter or a reusable model you can clean and reinsert.
Corroded or dirty spark plugs have difficulty igniting the engine, causing the mower to sputter, cut off or stop turning on. Installing a new spark plug annually solves many common start-up problems and saves money on lawn mower repair help. Use a gauge tool to position the spark plug's electrodes correctly before threading the new plug into the engine.
Dull or bent blades can trigger slow performance and ragged, inconsistent cutting. You may also notice excessive vibration if the blade is severely off-balance. Periodically checking for signs of bluntness, chipping or bending can help you decide whether the blade needs to be sharpened or replaced. Always use work gloves and disconnect the mower's power before handling the blade. Perform inspections whenever the mower malfunctions after hitting hard objects, as frequent strong impact increases wear.
