To change the oil on your Murray 38500B Tractor, first, run the engine for a few minutes to warm up the oil. Then, turn off the engine and disconnect the spark plug. Place an oil pan under the engine, remove the oil drain plug, and allow the old oil to drain completely. Replace the drain plug and add new oil as specified in the owner's manual.
If your Murray 38500B Tractor won't start, check the battery connections to ensure they are clean and tight. Verify that the fuel tank has enough fuel and that the fuel valve is open. Examine the spark plug for wear or damage and replace if necessary. Additionally, check the safety switches and ensure they are engaged.
To adjust the cutting height on the Murray 38500B Tractor, locate the height adjustment lever, typically found near the wheels. Move the lever to your desired cutting height position. Ensure that all wheels are adjusted to the same height for an even cut.
First, disconnect the spark plug to prevent accidental starting. Remove the mower deck and then the blades. Secure the blade in a vice and use a file or grinder to sharpen the cutting edge, maintaining the original angle. Reinstall the blades, ensuring they are balanced, and reattach the mower deck.
Check that the tire pressure is even on all sides and adjust if necessary. Inspect the mower deck to ensure it is level and adjust the deck height settings if needed. Examine the blades for sharpness and damages, and replace or sharpen as required.
Excessive vibration can be caused by unbalanced or damaged mower blades. Check to see if the blades are bent or have become unbalanced and replace or balance them as needed. Also, inspect the engine mounting bolts and tighten any loose connections.
Regular maintenance includes checking the oil level before each use, changing the oil every 50 hours of operation, inspecting and cleaning the air filter every 25 hours, and sharpening the blades every 25 hours or as needed. Additionally, perform an annual check of the spark plug and replace if necessary.
Maintain your tractor by regularly changing the oil, cleaning the air filter, and ensuring the spark plug is in good condition. Keep the tires properly inflated and the blades sharp to reduce engine strain. Avoid mowing wet grass and remove any debris from the mower deck to improve efficiency.
Ensure that the engine cooling fins are free of debris and dirt. Check the oil level to make sure it is adequate as low oil can cause overheating. Make sure the mower deck is clean and not clogged with grass clippings. If the problem persists, consult the owner's manual or a professional technician.
To store your Murray 38500B Tractor for the winter, clean the tractor thoroughly, including the mower deck. Change the oil and air filter, and add a fuel stabilizer to the fuel tank. Disconnect the battery and store it in a cool, dry place. Cover the tractor to protect it from dust and moisture.
