If that doesn't offer any insight, here is what you'll need to check:
1) Does the battery display a green light when the indicator is pressed? 2) Is the battery securely locked into place? 3) Does the Mower headlight turn on when the light button is pressed? If not, check again to make sure the battery is fully locked into place. 4) Are the handles fully extended to display the black lines on either side of the handle? If not, release the clasps and extend the handles the full distance. 5) When starting the mower, be sure to depress the safety down before pulling the bail handle.
If the above doesn’t get you up and running, please call us at 1-855-346-5656.
