G'day Mf and Jack,

The furthest back I can think of for lawn mowers would be the titanosaur sauropods which weighed more than 100 tons and were the heaviest creatures to ever walk the Earth.

Scientists have been analyzing 65 million-year-old dinosaur dung which shows that dinosaurs ate grass.

That would have to be the biggest power unit ever to cut grass. cool

To put that 100 tons into perspective ,the average weight of a Blue Whale is a 140 tons.

Cheers
Max.
