- Check the right front wheel for any foreign objects (like sticks, stones, or clumps of grass) and carefully remove them. Then try starting the mower again.
- The grass may be too thick or too tall for the mower to handle smoothly. 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 reduce strain on the mower—and then try again.
