Simply and clearly details the parts of a tractor and its uses. For example, "Tractor tires have deep grooves called lugs. Lugs help tires go through mud and water without getting stuck. Some tractors have duals for even more grip." Mentions such details as farmers tracking engine hours rather than miles, the power takeoff, and some kinds of machinery pulled by a tractor. There is a hands on activity that suggests how a child can do the work of a tractor when planting bean seeds. There is a short glossary, index, and bibliography.
