Can you damage a lawn mower by cutting long grass?

1. Overheating: Long grass can put a strain on the lawn mower's engine, causing it to work harder and generate more heat. This can lead to overheating, especially if the mower is not properly maintained or used in hot weather conditions. Overheating can damage various engine components, such as the piston rings, cylinder head, and gaskets.

2. Clogged Deck: As the lawn mower cuts through long grass, it generates a large amount of clippings. These clippings can accumulate on the mower's deck, clogging it and preventing proper airflow. A clogged deck can restrict the mower's ability to discharge grass clippings efficiently, resulting in uneven cutting and potentially damaging the mower's blades and deck.

3. Damage to Blades: Cutting long grass exerts extra force on the lawn mower's blades, increasing the risk of bending, dulling, or even breaking the blades. This can result in poor cutting performance and uneven grass cutting. Damaged blades can also pose safety risks as they may vibrate excessively or break off during operation.

4. Stress on Drive Components: Long grass can also put additional stress on the lawn mower's drive components, such as the transmission and drive belts. This can cause these parts to wear out prematurely or even break, resulting in costly repairs or replacements.

5. Reduced Efficiency: Cutting long grass requires the lawn mower to work harder, consuming more fuel and reducing its overall efficiency. This can be particularly problematic for older or less powerful lawn mowers.

To avoid potential damage, it is recommended to cut grass regularly when it is still at a manageable height. If you encounter long grass, consider using a trimmer or scythe to reduce its height before mowing with a lawn mower. Additionally, ensure that your lawn mower is well-maintained with sharp blades and a clean deck to prevent any issues when cutting grass.
