John Deere 48C without Deck Shields Operator's Manual

To adjust the cutting height, locate the height adjustment lever on the mower deck. Move the lever to the desired setting, ensuring all wheels are set to the same height for an even cut.
Perform maintenance every 25 hours of operation. This includes checking and changing the oil, cleaning the air filter, and inspecting the blades for wear. Also, lubricate all moving parts as per the user manual.
Check if the blades are sharp and properly installed. Ensure the tire pressure is even on all wheels, and verify that the deck is level. These adjustments can help achieve an even cut.
First, disconnect the spark plug for safety. Remove the mower deck and use a wrench to unscrew the blade bolts. Replace with new blades, making sure they are secure and properly oriented. Reattach the deck before using the mower.
After each use, remove grass clippings and debris from the deck using a brush or water hose. Be sure to disconnect the spark plug and avoid getting water into the engine components.
Check the fuel level and ensure fresh fuel is used. Inspect the spark plug for fouling and replace it if necessary. Also, verify that the battery is charged and connections are secure.
Ensure the blades are sharp and consider using mulching blades for better performance. Avoid mowing wet grass and adjust the mowing speed to allow for thorough mulching.
John Deere recommends using 10W-30 oil for most climates. Always check the user manual for specific oil recommendations based on your operating environment.
Clean the mower thoroughly and drain the fuel. Change the oil, remove the battery, and store it in a cool, dry place. Cover the mower to protect it from dust and moisture.
Always wear protective gear, including goggles and gloves. Keep bystanders away from the mowing area, and be cautious of debris that could be thrown by the blades. Ensure all safety devices are functioning before use.
