“It looked like he was struggling, so I pulled over and helped him,” he said. “That’s when I got my goal to mow lawns for free for the elderly, single moms and veterans.”
He then made it his mission to help others, starting the 50 Lawn Challenge to encourage people to help others in their community.
The challenge went viral in 2017 and now has 400 kids participating nationwide.
On his most recent tour of the country, Smith dedicated his time specifically to helping veterans.
“I’ve come across so many veterans that are struggling to get their lawn mowed,” he told ABC News. “If they served for our country, we should step up for them.”
“This is the least we can do,” he added. “This is the last thing they need to worry about.”
