Before starting your Murray riding lawn mower, carefully read its owner's manual. It contains key information on the safe operation of all aspects of the machine. Once you have read the manual, make sure all guards, shields and other safety mechanisms are in place before the key goes into the ignition. And thoroughly inspect the machine to make sure all of its parts are in working order.
Sit in the riding mower's seat.
Push the throttle/choke lever all the way forward to the "choke" position. It is located on the left side of your seat behind the lift lever.
Use your left foot to push the clutch/brake pedal all the way forward.
Put the key into the ignition. Then turn it to the "start" symbol. Once the engine turns over, allow the key to return to the "run" symbol.
Move the throttle forward to the "fast" position.
