Thousands of years ago, farmers had to plant even the tiniest seeds by hand. Luckily, inventors eventually created modern farming machines that can plant seeds in just a fraction of the time it once took. Future farmers and lovers of big machines will enjoy finding out how these devices work through accessible text, fun fact boxes, and beautiful color photographs that complement key concepts. A clever concluding activity further connects young readers to the motivating content.
