How to Troubleshoot a John Deere Lawn Tractor Engine

John Deere lawn tractors make mowing a large yard or acreage much easier than a traditional push mower. These tractors feature a small engine that provides power to the drive system and the mowing deck. The engine is a traditional combustion type that uses oil to lubricate internal components and gasoline for the combustion process. Although the lawn tractor engine is designed to last for many years, sometimes you may experience problems that require some troubleshooting.
