Introduction: Why Regular Lawn Mower Maintenance Matters
A perfectly manicured lawn is a source of pride for many UK homeowners. However, achieving that lush, green finish relies heavily on a well-maintained lawn mower. Regular maintenance isn’t just about keeping your machine running; it’s about ensuring optimal performance, extending its lifespan, and, crucially, maintaining safety. Neglecting maintenance leads to a poor cut quality, increased fuel (or electricity) consumption, frustrating breakdowns, and can even present potential hazards. The type of mower you have – petrol, electric, or robotic – will dictate the specifics of the maintenance required, but the principle remains the same: preventative care saves you time, money, and hassle in the long run.
Lawn Mower Maintenance Schedule: A Seasonal Guide
Here’s a breakdown of essential maintenance tasks, organised by season:
Spring
- Blade Sharpening: Essential before the peak growing season. Dull blades tear the grass, leading to browning and disease.
- Oil Change (Petrol Mowers): Replace the oil after winter storage.
- Spark Plug Check (Petrol Mowers): Inspect and replace if necessary.
- Air Filter Check (Petrol Mowers): Clean or replace as needed.
- Battery Check (Electric/Robotic): Ensure fully charged and in good condition.
Summer
- Regular Deck Cleaning: Remove grass clippings build-up frequently to prevent corrosion and ensure efficient cutting.
- Blade Inspection: Check for damage and sharpness. Minor sharpening may be needed mid-season.
- Cable Inspection (Electric Mowers): Check for any cuts or damage to the power cable.
Autumn
- Final Cut & Clean: Give the mower a thorough cleaning before winter storage.
- Oil Change (Petrol Mowers): Another oil change before storage is recommended.
- Fuel Stabiliser (Petrol Mowers): Add fuel stabiliser to the fuel tank to prevent degradation during storage.
Winter
- Winter Storage: Store the mower in a dry, sheltered location.
- Battery Removal (Electric/Robotic): Remove the battery and store it in a cool, dry place.
- Belt Inspection (Petrol Mowers): Check belts for wear and tear.

Lawn Mower Blade Sharpening: A Complete Guide
Sharp blades are crucial for a healthy lawn. You can sharpen blades using a file or a grinder. Always wear safety glasses and gloves.
- Filing: Use a metal file to carefully remove material from the blade’s cutting edge, maintaining the original angle.
- Grinding: Use a bench grinder with a suitable grinding wheel. Be careful not to overheat the blade.
- Balancing: After sharpening, use a blade balancer to ensure the blade is balanced. An unbalanced blade causes excessive vibration.
Winterising Your Lawn Mower: Preparing for Storage
- Fuel Stabiliser (Petrol Mowers): Add fuel stabiliser (£12.50) to the fuel tank.
- Oil Change (Petrol Mowers): Change the oil.
- Clean the Mower: Remove all grass clippings and debris.
- Battery Removal (Electric/Robotic): Remove the battery and store it in a cool, dry place.
- Storage Location: Store the mower in a dry, sheltered location.
Common Lawn Mower Problems & Troubleshooting
| Problem | Possible Cause | Troubleshooting |
|---|---|---|
| Difficult Starting (Petrol) | Old fuel, dirty air filter, faulty spark plug | Drain old fuel, clean/replace air filter, replace spark plug (£10.00 for a set) |
| Uneven Cutting | Dull blades, uneven ground, incorrect cutting height | Sharpen blades, level the ground, adjust cutting height |
