Louisville, Ky. (WHAS11) - The University of Louisville's fleet of lawnmowers is going green.
They'll soon be running on propane gas instead of gasoline.
Last year they tried converting one of their push mowers, to see if it was possible.
It worked so well they decided to switch over their entire fleet; 8 push mowers, 5 riding mowers and two walk-behind mowers.
Mowers powered with propane burn up to 30 percent less fuel, generate less carbon waste and are safer and easier to maintain than mowers powered with gasoline.
