My Big Wimmelbook-Tractors Everywhere brings kids to a bustling farm where tractors are chugging away: churning up the fields, shoveling scrap, mowing grass, and hauling bushels of apples and potatoes. Children can follow a cast of hard workers and their machines through rural life in the spring, summer, fall, and winter, discovering how the seasons change what's going on in nature and which jobs the tractors do. There's also a spread of diagrams with simple labels so curious kids can learn to point out parts like the tires, cab, and engine.
