Elmo and Abby are helping Farmer Todd feed the cows. They need the tractor to carry the heavy hay, but the tractor is broken. This is a problem! They wonder if there's another way to bring the heavy hay to the cows. What if they use something with wheels, like the wagon and pull the wagon together to move the hay? Let's try! It works. They didn't give up, and they brought the hay to feed the cows.
