How Does a Tractor Work?

Have you ever wondered how one tractor can do so many different jobs?

A tractor is much more than a big machine with giant tires. Inside, powerful systems work together to pull heavy loads, move across rough ground, lift equipment, and power all kinds of farm tools.

How Does a Tractor Work? takes curious young readers onto the farm to discover the amazing engineering inside one of agriculture's most important machines.

Kids will discover how a diesel engine creates power, how the transmission sends that power to the wheels, and why tractors use low gears and deep, wide tires to pull hard while moving slowly.

Then discover what makes a tractor so versatile! See how the three-point hitch holds and lifts tools, how hydraulics use pressurized oil to move a front loader, and how the PTO can send power to attachments.

Young readers will see tractors using loaders, mowers, cultivators, planters, and trailers while learning how each system helps one machine perform many different jobs.

With colorful illustrations and easy-to-understand explanations, How Does a Tractor Work? turns a day on the farm into an exciting lesson in machines and engineering.

Perfect for curious kids who love tractors, farms, big machines, engineering, and discovering how things work!
