Tips to Keep Your John Deere Running Smoothly
If you own a John Deere—whether it’s a lawn tractor, zero-turn mower, or compact utility tractor—you already know how reliable these machines are. But like any powerful equipment, they need proper care to stay in top shape season after season.
Below are essential maintenance tips to help keep your John Deere running smoothly, reduce downtime, and extend the life of your investment.
✅ 1. Regular Oil Changes
Engine oil is the lifeblood of your John Deere. Check the oil level before each use, especially during mowing season. Replace the oil and filter according to your manual (usually every 25–50 hours of use).
Tip: Use John Deere-approved oil and filters for optimal performance.
✅ 2. Keep the Air Filter Clean
A dirty air filter causes your engine to work harder, consume more fuel, and lose power. Inspect the air filter monthly and replace it if it looks clogged or damaged.
Quick trick: Tap the filter gently to remove loose debris—never use compressed air, as it may damage the filter.
✅ 3. Sharpen the Blades
Sharp mower blades = clean cuts + healthier grass.
Signs your blades need sharpening:
Torn or frayed grass tips
Uneven cutting patterns
Sharpen or replace the blades every 25 hours of mowing or at the start of each season.
✅ 4. Check Tire Pressure
Low or uneven tire pressure affects:
Cutting height
Traction
Fuel efficiency
Check the tires before each use, especially if your mower has been stored for a while.
✅ 5. Clean the Deck After Each Mow
Grass buildup under the cutting deck can lead to:
Rust
Reduced airflow
Poor cutting performance
Use a scraper or hose (if your model has a deck wash port) to remove debris.
✅ 6. Use Fresh, Clean Fuel
Old fuel with ethanol can cause engine problems. If your mower has been unused for 30+ days, drain the tank or use a fuel stabilizer.
Best practice: Fill up with fresh gasoline before each new season.
✅ 7. Maintain the Battery
Batteries tend to fail due to corrosion or lack of charge.
Clean terminals with a wire brush and baking soda solution.
Disconnect and store the battery indoors during winter.
✅ 8. Grease Moving Parts
Lubricate key pivot points and joints every 25 hours of use. This prevents wear and extends the life of your machine.
✅ 9. Follow the Annual Maintenance Schedule
John Deere equipment comes with an annual maintenance checklist—follow it religiously.
Most yearly service includes:
Oil + filter change
Air filter replacement
Spark plug check
Blade sharpening
✅ 10. Store It Properly
When off-season arrives, don’t just park it and forget it.
Proper storage includes:
Cleaning the deck
Draining or stabilizing fuel
Removing the battery
Covering the mower
A dry, covered space = protection from rust and weather damage.
Final Thoughts
Routine maintenance keeps your John Deere powerful, efficient, and dependable. A few minutes of care after each use can prevent expensive repairs later.
Whether you’re mowing your backyard or managing acres of land—proper upkeep ensures your John Deere works harder, lasts longer, and always starts when you need it.
