A man is on a mission to help the elderly, veterans, single mothers and the disabled one lawn at a time.

Rodney Smith is aiming to mow lawns in all 50 states to help those in need through the Raising Men Lawn Care Service.

Smith told Shannon Bream on "Fox News @ Night" that he was inspired to do good after he stopped to help an elderly man in need while mowing his own lawn.

"That night I decided to mow free lawns for the elderly, disabled, single moms and veterans," he said Friday.

The Alabama-based Smith said that his original goal was to mow 40 lawns by winter's end while working toward his bachelor's degree in computer science.

"I reached 40 lawns so quick that I upped my goal to 100," he said. "A month and a half later I reached my hundredth lawn."

He added that his service has implemented the "50 Yard Challenge," which is issued to children nationwide.

The challenge, for kids who accept it, is to mow 50 lawns free of charge in their communities, then being progressively rewarded with T-shirts and protective outerwear.

"Once they reach 50, we fly to wherever they are, we do lawns with them and we also give them a brand-new lawnmower."

Smith said that his good deeds let him know he's making a difference for those in need.
