Our pick
Using a one-acre-rated X430 on about half an acre creates more recovery room than sizing at the limit. This does not promise twice the real output. Wet grass, slopes, obstacles and charging time still shape the week.
Capacity reserve matters when weather removes mowing days and growth accelerates.
