- Check the left front wheel for any foreign objects (like sticks, rocks, or clumps of grass) and remove them. Then try starting the mower again.
- The grass may be too thick or too tall for the mower to handle. Move the mower to a spot with shorter or thinner grass, then restart.
- If the error still appears, mow your lawn down to its usual maintenance height first—this helps prevent overload—and then try again.
