<p>Tractor Mac loves that he is the only tractor in his farm family. Then one day, his friend Iron Dave the train brings him to a tractor dealership and shows him a whole lot full of big red tractors that look just like him. Are these tractors his <i>real</i> family? Tractor Mac is excited to find a place with so many familiar faces, but sad that he might have to leave the farm to be with them. Then all of the big red tractors in the lot help him to understand that his real home is with the family he's found with the animals and machines at the farm.</p>
