When summer hits full stride, your equipment takes the heat—literally. If your mower starts acting up in July, overheating is often the culprit. The good news? Most issues are easy to spot and fix before they turn into costly repairs.
1. Loss of Power
If your mower struggles in thick grass or feels weaker than usual, overheating could be reducing engine efficiency.
Fix: Check your air filter and cooling fins. A clogged filter restricts airflow and traps heat.
2. Engine Shutting Off
Does your mower run fine for a bit, then suddenly die? That’s a classic overheating symptom.
Fix: Let it cool, then inspect for blocked airflow or low oil levels.
3. Burning Smell
A hot, burning odor is a red flag. This can indicate overheating belts or engine components.
Fix: Inspect belts for wear and make sure nothing is rubbing or seized.
4. Excessive Vibration
Overheated components can warp or wear unevenly, leading to vibration.
Fix: Check blades, spindles, and pulleys for damage or imbalance.
5. Smoke from the Engine
Light smoke can mean oil is burning due to excessive heat.
Fix: Check oil level and condition. Replace if dirty or low.
6. Hot Engine Housing
If the engine feels unusually hot to the touch, airflow is likely restricted.
Fix: Clean debris from cooling fins and engine housing.
7. Poor Cutting Performance
Heat affects engine output, which directly impacts cutting ability.
Fix: Replace dull blades and ensure belts are properly tensioned.
Prevent Overheating Before It Starts
- Replace air filters regularly
- Keep engine components clean
- Check oil levels before each use
- Inspect belts and spindles mid-season
