This video will show you how to change the gas on a Troy-Bilt riding mower. Depending on your model, the instructions in this video may vary slightly. Always be sure to check your operator's manual for detailed instructions.
Place your mower on a flat, level surface. Turn the mower off. Make sure the engine is cool. Remove the ignition key and disconnect the spark plug ignition wire.

Using the Arnold Siphon Pump, place the top port into the gas tank on the engine, and the bottom port into a proper container.
Prime the pump by pumping the handle three to four times. Once the liquid begins to flow, it will flow without further pumping.
Remove the Arnold Siphon Pump and add new gas.
Replace the gas cap.
