I just read an article about that same topic. It said that the lawn is
"rolled" with a small roller attached to the rear of the mower. you would
mow back and forth and each direction would "roll" the blades of grass the
opposite way.

Yes, you're right. I didn't know they had those. I found a web site:

The rollers create the same effect as a reel type lawn mower.
