Press the key down. Thats the secert, turning it to the right only turns the lights on. Then press the starter button. Yours won't have a glow plug, just press the key down, (the fuel gauge will move if the battery is good at this point) advance the hand throttle (this is how you shut the tractor down) and press the button. Now if it just cranks, get off the seat and go the injector pump, you'll find a plunger that you can build fuel pressure up with.
