John Deere owners know how important it is to keep their lawn equipment in tip-top shape. Whether maintaining a small residential lawn or managing acres of farmland, proper care of your John Deere lawn mower is essential for high performance and equipment longevity.
In this blog, we'll explore some quick fixes and DIY maintenance tips to help you keep your John Deere mower running smoothly all season long. And when you’re ready to find a lawn mower to tackle any task, visit Tennessee Tractor online or in-person. We would love to help you find the perfect lawn tractor or zero-turn mower.
Regular Cleaning
One of the simplest yet most effective ways to maintain your John Deere lawn mower is through regular cleaning. Just like you, after a long day of work, your lawn mower deserves a bath, too! After each use, take a few minutes to remove grass clippings and debris from the deck and undercarriage. This prevents rust buildup and ensures proper airflow, which is critical for engine cooling. For stubborn buildup, use a bristled scrubber or a blower to clean hard-to-reach areas.
Fuel Management
Proper fuel management is important for the longevity of your John Deere lawn mower. If your mower will be idle for more than 30 days, it's essential to add a fuel stabilizer to prevent clogging in the carburetor. This simple step can save you from costly carburetor cleaning or replacement down the line. When storing your mower for the off-season, either drain the fuel entirely or add a winter stabilizer to the full tank. This practice will make sure your mower starts up quickly when spring arrives.
Oil Changes
Regular oil changes are vital for maintaining your John Deere lawn mower's engine. Fresh oil keeps engine parts properly lubricated, reducing friction and heat buildup. As a general rule, change your mower's oil after every 25 to 50 hours of use or at least once per season. When changing the oil, be sure to use the grade recommended in your mower's manual. Using premium-grade oil can improve engine operation, lubrication, and fuel economy.
Blade Maintenance
Sharp mower blades are essential for a healthy lawn and efficient mowing. Dull blades tear the grass instead of cutting it cleanly, which can lead to an unhealthy lawn and put extra strain on your mower's engine. Inspect your blades regularly and sharpen them at least once per season or after every 25 hours of use. If you're not comfortable sharpening the blades yourself, Tennessee Tractor's service department can handle this task for you.
Tire Pressure
Proper tire pressure is often overlooked but is crucial for even mowing. Uneven tire pressure can cause the mower deck to tilt, resulting in an uneven cut. Before each mowing session, inspect your tires and check the pressure. If you find yourself constantly dealing with flat tires, consider upgrading to John Deere's innovative Tweel tires, which never go flat and provide a consistently even cut.
Spark Plug Maintenance
A well-maintained spark plug ensures an easy start and smooth operation of your John Deere lawn mower. Replace your spark plug annually or after every 100 hours of use. When installing a new spark plug, make sure to set the gap correctly according to your mower's specifications. This simple maintenance task can significantly improve your mower's fuel efficiency and overall performance.
Battery Care
For electric-start models, proper battery maintenance is vital for steady running. Keep the battery terminals clean and free of corrosion. If your mower struggles to start, check the battery connections first. A weak battery can cause starting issues, so consider replacing it if it's more than three years old.
