I have not tried electric goats. I'd go with the grass powered ones.

I'd go with a riding lawn mower for that much lawn. I mean, that's a lot of lawn for even the biggest push mower, and electrics have even smaller blades and are less powerful in case you let the grass get too tall and then try to cut it.

I've never been much for bagging, but it's a nice feature if you have deciduous trees and need to clear leaves in the fall. All other times I either side discharge or mulch.
