Starting and Operating the TB120

It’s essential to adjust the cutting height according to the type of grass and the season. Generally‚ a higher cutting height is recommended during hotter months to help the lawn retain moisture and prevent sun scald. Regularly adjusting the cutting height can significantly impact the health and appearance of your lawn.
