For a complex 1-acre lawn with rabbit holes and multiple obstacles, I strongly recommend getting a professional company to perform a site survey.

With a plot that size, many factors will dictate which mower is actually suitable—specifically tree coverage (which can block GPS signals), WiFi/4G connectivity across the entire area, and how the mower’s suspension handles the uneven ground. A professional assessment ensures you don't invest in a high-end machine only to find it loses signal or gets stuck in your specific terrain.
