Murray 46379x30A Parts Manual

To start the Murray 46379x30A Tractor, ensure the parking brake is engaged, the PTO switch is off, and the gear is in neutral. Insert the key and turn it to the 'Start' position until the engine fires.
Check if the battery is charged and terminals are clean. Ensure the fuel tank is full and the fuel valve is open. Verify that the spark plug is clean and properly connected.
Regular maintenance should be performed every 50 hours of operation or at the start of each season, including oil changes, air filter checks, and blade inspections.
Use SAE 30 motor oil for engines operating in temperatures above 40°F. For colder temperatures, SAE 5W-30 is recommended.
Check if the deck is level and the blades are sharp and balanced. Make sure tire pressure is even on all wheels and that the ground speed is appropriate for the mowing conditions.
Excessive vibration can be caused by unbalanced or damaged blades, debris caught in the deck, or loose engine mounting bolts. Inspect and tighten all components as necessary.
First, disconnect the spark plug wire to ensure safety. Lift the mower deck and use a wrench to remove the blade retaining bolt. Replace the blade and securely fasten the bolt.
The recommended tire pressure for the Murray 46379x30A Tractor is typically 14 PSI for the front tires and 10 PSI for the rear tires. Always refer to the owner's manual for specific guidance.
Remove the air filter cover and take out the filter. If it's a foam filter, wash with mild detergent and water, then dry it thoroughly. For paper filters, gently tap to remove debris or replace if necessary.
Inspect the battery terminals for corrosion, ensuring they are clean and tight. Check the alternator and voltage regulator for proper function. Replace the battery if it's old or damaged.
