Tractor Mac wakes up eager to start the day. Plow, plant, scoop, mow--there's always a new chore for him and his animal and vehicle friends to do at the farm. When the day is done, he washes up and goes to bed, excited to see what the next day will bring.

All the vehicles and animals on Stonybrook Farm are enlisted to help build a new swimming hole for their town's residents. It is a big job, but Tractor Mac and his pals are willing to lend a hand. But a tractor named Deke thinks he can do it all by himself--and do it better than everyone else. He soon learns that a complex job is done best when each member of a team does his or her part.

This new edition to the Tractor Mac series is a board book that teaches children about the different colors of the rainbow. Tractor Mac and his vehicle and animal friends, including Sibley the horse, Pete the pig, and Goat Walter, show kids around Stony Meadow Farm in order to observe the colors of various objects found on the farm.
