Murray G4315010 Parts Manual

To start the Murray G4315010 tractor, ensure the parking brake is engaged, place the throttle lever in the 'fast' position, turn the ignition key to the 'start' position, and release it when the engine starts.
If the engine does not start, check the fuel level, ensure the battery is charged, inspect spark plugs, and verify that all safety switches are engaged.
Uneven cutting can be addressed by checking the tire pressure, leveling the mower deck, and ensuring that the blades are sharp and properly installed.
The oil should be changed every 50 hours of operation or at the start of each season, whichever comes first.
SAE 30 motor oil is recommended for use in temperatures above 32°F, while SAE 10W-30 is suitable for colder temperatures.
To replace the mower blades, disconnect the spark plug, raise the mower deck, use a wrench to remove the blade bolt, replace the blade, and tighten the bolt securely.
Excessive vibration might be due to unbalanced blades, loose bolts, or damaged components. Inspect and balance the blades, and ensure all bolts are tight.
To clean the air filter, remove the cover, take out the filter, and gently tap it to remove debris. If it's too dirty, replace it with a new one.
At the end of the season, change the oil, clean the mower deck, check and replace the air filter, charge the battery, and store the tractor in a dry place.
To adjust the mower deck height, locate the adjustment lever or knob, usually near the driver's seat, and move it to the desired position.
