Navigating through common riding mower problems can be daunting, but understanding whether it's a DIY fix or a job for a repairman is crucial. Here, we outline five prevalent issues seen by Sears Home Services technicians, offering troubleshooting tips to address each concern effectively.

KEY TAKEAWAYS

  • Common riding mower problems include issues with starting, engine stalling, rattling/humming noises, rough operation, and ineffective grass cutting.
  • Troubleshooting steps for these problems include checking fuel quality, inspecting spark plugs, ensuring battery functionality, examining belts for wear and tear, and lubricating moving parts.
  • Some problems may require DIY fixes such as changing fuel and cleaning filters, while others may necessitate professional repair, such as replacing damaged parts like carburetors or belts.

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: If fuel has been sitting in your tank all winter, change it. Also check the spark plug for corrosion or other damage, and eyeball your air filter to make sure it’s clean. Still won’t start? Try starting fluid. If that fails, your ignition switch could be the problem.

Problem #2: Your Engine Turns Over But Dies Quickly

Likely Culprit: Your battery may be having trouble keeping a charge. Juice it up for 24 hours and try again. If it dies when you take your foot off the brake, your seat switch, which turns off the engine when there’s no driver in the seat, could be to blame. Make sure it’s plugged in. If it is, you could have a short. Still not working? You may need to replace it.

Problem #3: The Engine Rattles and Hums

Likely Culprit: Check the fan belt for wear and tear, lubricate the motor and check for any loose parts that could be vibrating when the engine is running.

Problem #4: It Runs Roughly

Likely Culprit: If the carburetor is clogged, your engine won’t operate as well as it should. It might be time to replace it. If you notice the problem after running over something, like a rock or tree root, you may have damaged your flywheel key.

Problem #5: It Doesn’t Cut the Grass

Likely Culprit: Check your blade belt. If it’s worn or cracked, have it replaced.
