A lot of people keep their mower looking clean but skip the actual servicing — and that’s usually when small problems turn into expensive ones. Here’s what to watch for.

1. It’s harder to start than it used to be. A mower that took one pull last year and now takes ten is telling you something — usually fuel, spark plug, or air filter related, and usually cheap to fix if caught early.

2. The cut looks uneven or the grass is being torn, not cut. This is almost always blades that need sharpening or balancing. Blunt blades also make the engine work harder, which shortens its life.

3. It’s smoking, smells off, or running rough. Don’t wait on this one — it can mean anything from an oil issue to something more serious, and running it in that state can turn a minor fix into a major one.

4. It’s vibrating more than normal. Often a sign of an unbalanced blade or something loose. Worth checking before it shakes something else loose too.

5. It’s been over 12 months since a proper service. Even if nothing seems wrong, a yearly service — oil change, filter checks, blade sharpening, general once-over — catches small wear issues while they’re still small.

Regular servicing is genuinely one of the cheapest ways to avoid a big repair bill later. If it’s been a while, or something on this list sounds familiar, bring it in — no appointment needed.
