Frank and his father, Greg Giaccio, arrived at the White House, and the 11-year-old - the proprietor of FX Mowing - got to work in the Rose Garden and met the president.
Press secretary Sarah Huckabee Sanders shared the request with the media and said the White House would grant the wish.
On Wednesday, Sanders confirmed Frank would work with the groundskeeping crew to cut the grass on the Rose Garden lawn. But he said that Frank, the oldest of four children, began supporting Trump early in the Republican primary debates.
"That's the real future of the country right there - we're lucky", the president said.
Trump tweeted a video in the afternoon that recapped Frank's day, which included his appearance in the briefing room, meeting the President and Vice President Mike Pence and visiting the Oval Office.
He told CNN that mowing the lawn was such an honour that he even waived his usual $8 fee.

"Even though I'm only 10, I'd like to show the nation what young people like me are ready for", Sanders said the child wrote.
Giaccio, who has his own lawn mowing business wrote a letter to the President asking if he could mow the lawn at the White House. "Maybe he'll be president".
And by the looks of things, the National Park Service may be out of a job, as Frank is not only all business when working, but he's also damn good.
Giaccio capped off the day with a trip to the Oval Office.
