But before you panic and start thinking about expensive repairs or replacements, let’s take a closer look at what could be causing the problem. One possible culprit for that high-pitched noise is a loose or damaged belt. Lawn mowers have belts that connect various components, such as the engine and the cutting blades.
Over time, these belts can become loose or worn out, leading to strange noises. Another potential cause could be a damaged flywheel key. The flywheel key is a small part that connects the engine’s crankshaft to the flywheel.
If it becomes damaged or sheared, it can cause the engine to run unevenly and produce a high-pitched noise. Additionally, a faulty spark plug or ignition coil could be to blame. The spark plug provides the spark that ignites the fuel mixture in the engine, while the ignition coil helps generate and deliver the electrical charge needed for combustion.
If either of these components is not functioning properly, it can result in a loud, screeching sound when starting the mower. So, how can you identify and fix these issues? It’s always a good idea to start by visually inspecting your lawn mower for any obvious signs of damage. Check the belts for any signs of wear or looseness.
