John Deere Select Series X700 Operator's Manual

To change the oil, ensure the engine is cool. Remove the drain plug and let the oil drain into an appropriate container. Replace the oil filter, and then refill with the recommended oil type and quantity as specified in the user manual.
Check the battery connections for corrosion and ensure they're tight. Make sure there's fuel in the tank, and check the spark plugs for wear or damage. If the problem persists, consult a professional technician.
Sharpen the mower blades at least once a mowing season or more frequently if you notice the grass is not cutting cleanly. Dull blades can tear the grass rather than cut it.
The recommended tire pressure can typically be found in your user manual or on a sticker under the seat. It's generally around 10-14 PSI for the front tires and 6-10 PSI for the rear tires.
Ensure the blades are sharp and balanced, check the deck level, and maintain proper tire pressure. Also, mow at the right speed and height for the grass conditions.
Use unleaded gasoline with a minimum octane rating of 87. Avoid fuels with more than 10% ethanol content, as they can damage the engine components.
After each use, scrape off any grass clippings and debris using a plastic scraper. Periodically, you can also use a hose to wash under the deck, but ensure the engine is off and avoid getting water on sensitive components.
Excessive vibration can indicate unbalanced blades or debris build-up. Inspect and clean the mower deck, and check that the blades are properly installed and balanced.
Regularly check the battery terminals for corrosion and clean them as needed. Keep the battery charged, especially during off-season storage, and consider using a trickle charger to maintain charge levels.
Perform regular oil changes, check and replace air filters, sharpen blades, inspect belts for wear, and ensure tire pressure is correct. Refer to the maintenance schedule in your user manual for detailed guidance.
