Otis

Otis is a special tractor. He loves his farmer and he loves to work. And he loves the little calf in the next stall, whom he purrs to sleep with his soft motor. In fact, the two become great friends: they play in the fields, leap hay bales, and play ring-around-the-rosy by Mud Pond.

But when Otis is replaced with the big yellow tractor, he is cast away behind the barn, unused, unnoticed...until the little calf gets stuck in Mud Pond. Then there is only one tractor—and it's not big or yellow—who can come to the rescue. It is little old Otis who saves his friend. It is Otis who saves the day.
