Happy Skies Farm is a big farm, and it needs big equipment to manage its work. But Casey has two good friends – Big Red the Magnum and Sammy Steiger – who help her get the job done. Along with Tillus the worm, Casey shows us how Big Red and Sammy help her with her work.
In order to understand how powerful these two big tractors are, Casey first explores the concept of horsepower, showing us the evolution of tractors since they first appeared in 1920. Weight balancing and power output are demonstrated, and wheel size and shape are discussed, as Casey explains how a tractor is designed so it won’t sink into loose soil or flatten the soil too much. Finally, we see the inside of the tractor from the operating console to the interior mechanical workings. A glossary of terms concludes the narrative.
Big tractors are a necessity on large farms, and knowing as much as possible about the equipment they’re operating will be helpful to farm kids. But even those who live in the city or suburbs will be fascinated by this large and useful equipment. Big Tractors With Casey & Friends is a great read for anyone interested in learning how big farm equipment works.
