Book excerpt: In this jacketed hardcover edition written and illustrated by Billy Steers, Tractor Mac: Autumn is Here features Tractor Mac and his vehicle and animal friends in a story about the joys and challenges of change. Fergus the calf doesn’t want autumn to come to Stony Meadow Farm. Not if it means the cornstalks are cut, the trees lose their leaves, and his bird friends migrate away. Why can’t things just stay the same? But with the help of Tractor Mac and the rest of his friends, Fergus realizes that there are plenty of fun things about autumn, too, as he learns to appreciate what makes each season special.
