That’d make short work of my two and a half acres of open field.
I do my 5 acres with a 7mph 60’ zero turn. It takes 2.5 hours and 2.5 gallons of gas. This used to be a hay field and is only now becoming nicely filled in lawn. But if my mower went any faster it would bounce right into orbit.
You can usually see objects in the road a lot further away at high speed, and they usually get removed by someone other than you. Also, your car, unlike your mower, isn’t designed to impact everything more than 3 inches off the ground. I’d hate to mow over a rake or hedge clippers or any kind of object left by someone in a field at any speed let alone highway or autobahn speeds.
