How Do You Troubleshoot Riding Lawnmower Problems?
• Check the basic mower functions to determine where you need to look to diagnose the problem you are having with your mower. Here are the basic parts of a typical mower: • Engine • Belts and pulleys • Mower deck • Wheels and axle assemblies • Blades • Transmission/drive system • Safety system Check each part of the mower to make sure it is working. First, you must make sure the engine is running. This should be obvious, and no other part of the machine will work if the engine won’t start. Here is a checklist to get started diagnosing engine problems. • Check the crankcase lubricant (motor oil). Many modern engines have an oil sensor that shuts off the engine if the oil level is too low for it to operate safely. • Check the fuel. You may want to check the fuel pump, filter, and fuel lines for leaks or blockages. • Check the air filter. Dirty air filters rob the engine’s performance, and if the filter is sufficiently stopped up, it will not allow it to crank. • Check the carburetor. Mak
