Professional mower operator Hali Rieman has officially mowed her way into the history books.

At Louisville’s Waterfront Park, Rieman crushed a new Guinness World Record by precision-mowing an entire American football field in a staggering 14 minutes and 51 seconds.

Using a high-powered ride-on mower, she tackled the massive field in front of a live crowd during Rehlko’s “Cutting History” event.

Turns out, grass really didn’t stand a chance.
