Murray 385004x52A Parts Manual

To change the oil on your Murray 385004x52A Tractor, first ensure the engine is off and cool. 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 refill with the recommended oil type and amount as specified in the manual.
If your tractor won't start, check the battery connections to ensure they are clean and tight. Examine the spark plug for signs of wear or damage, and replace if necessary. Ensure the fuel tank has clean fuel and the fuel filter is not clogged.
To maintain the cutting blades, regularly inspect them for dullness or damage. Sharpen the blades using a grinder or file, ensuring a balanced edge. Replace blades if they are bent or excessively worn. Always disconnect the power before servicing the blades.
The Murray 385004x52A Tractor is designed to run on unleaded gasoline with an octane rating of 87 or higher. Avoid using fuel with more than 10% ethanol content.
The air filter should be checked before each use and replaced at least once a season or every 25 hours of operation, whichever comes first. More frequent replacement may be necessary in dusty conditions.
Engine overheating can be caused by low coolant levels, a clogged air filter, or a malfunctioning cooling fan. Check the coolant level and top it off if necessary. Clean or replace the air filter and ensure the cooling fan is working properly.
Uneven cutting can result from a misaligned deck, dull blades, or uneven tire pressure. Check that the mower deck is level, the blades are sharp, and the tire pressure is equal on all sides. Adjust as needed.
The recommended tire pressure for the Murray 385004x52A Tractor is typically between 10-14 PSI for the rear tires and 12-15 PSI for the front tires. Always refer to the owner's manual for specific recommendations.
To clean the mower deck, first ensure the tractor is off and disconnect the spark plug. Use a garden hose to spray off grass clippings and debris from the deck. For stubborn residues, use a plastic scraper or brush. Allow the deck to dry before reconnecting the spark plug.
Excessive vibration may be caused by unbalanced blades, loose components, or a bent crankshaft. Check the blades for balance and tighten any loose parts. If the problem persists, inspect the crankshaft for damage.
