I assume the biggest difference is the area it can handle. I mow about 2 acres of grass, and none of the little mowers are close to fully replacing my zero turn mower. This seems like it could work well for me.
2 acres is almost a hectare (100mx100m). Just a curious question... May I ask if there is a special reason for it to be all grass? Also, could part of it be grazed by animals ?
