How to determine what’s wrong with your mower, and if it’s a DIY fix or a job for a repairman.
With spring in full swing, it’s time to rev up your riding lawn mower. But like any piece of machinery, riding mowers don’t always work like they should, especially after a long winter’s storage.
Here are five common riding mower problems Sears technicians typically see, and what you should do about them.
Problem #1: The Engine Cranks But Doesn’t Start
- Likely Culprit: Old fuel, spark plug corrosion, dirty air filter, or ignition switch issues.
- DIY Fixes:
- Replace old fuel with fresh gasoline.
- Inspect the spark plug for corrosion and replace if necessary.
- Check the air filter and clean or replace it if it's dirty.
- Use starting fluid as a last resort if the engine still won’t start.
- Technician Needed: If the issue persists after these checks, the ignition switch might be faulty and require professional attention.

- DIY Fixes:
- Charge the battery for 24 hours and retry.
- Ensure the seat switch is properly connected.

Problem #4: It Runs Roughly

- Inspecting and possibly replacing the carburetor if it is clogged.
