🚜 How Tractors Work
A tractor is much more than just a big vehicle — it’s a mobile power source that can connect to hundreds of different attachments. From ploughing and planting to spraying and harvesting, tractors make it possible to feed billions of people. Modern tractors are packed with computer technology, GPS navigation and sensors that would have seemed like science fiction to farmers just 50 years ago.
🚜
Combine Harvester
- Cuts, threshes and cleans grain all in one pass
- Header can be up to 12 metres wide
- Processes up to 40 tonnes of grain per hour
- GPS steers itself to within 2.5 cm accuracy
🚗
The Modern Tractor
- Engine can produce over 600 horsepower
- Tyres can be 2 metres tall
- Air-conditioned cab with touchscreen computer
- Can pull equipment weighing 20+ tonnes
🌿
Ploughing
- Ploughs turn over soil to bury weeds and mix nutrients
- One tractor can plough 4 hectares per hour — that’s 4 football pitches!
- Modern ploughs have up to 12 blades
- Ploughing has been done for over 5,000 years
🌏
GPS & Precision Farming
- Satellites guide tractors to within 2 cm of the planned path
- Sensors measure soil nutrients, moisture and crop health
- Drones fly above fields to spot diseased plants early
- Reduces waste — fertiliser only goes exactly where needed
⛽️
The First Tractors
- Steam-powered tractors appeared in the 1850s
- The first petrol tractor was built by John Froelich in 1892
- Henry Ford’s Fordson in 1917 made tractors affordable for farmers
- Before tractors, horses did all the heavy farm work
🍋
What Tractors Grow
- UK farms produce 14 million tonnes of wheat per year
- A single field can feed hundreds of families for a year
- Tractors also plant, spray, bale hay and dig up root vegetables
- Farming feeds 8 billion people — impossible without tractors
✨ Amazing Tractor Facts
🚌 The biggest tractor in the world is the Big Bud 747 — it weighs 43 tonnes and its engine produces 900 horsepower!
🌿 A single combine harvester can harvest enough wheat in one day to make 70,000 loaves of bread.
⛳ Modern tractors have continuously variable transmission (CVT) — no gears at all! The engine automatically finds the most efficient speed.
🌏 Some farms in the UK now use fully autonomous tractors — they drive themselves with no one in the cab.
🔥 Tractor pulling is a real sport! Modified tractors compete to pull a sledge 100 metres. Engines can produce over 10,000 horsepower!
♿ Before the tractor, it took a horse and human team 3 days to plough a field that a modern tractor ploughs in under 1 hour.

📚 Key Words
combine harvester
A machine that harvests crops by cutting, threshing and cleaning grain all in one operation.
horsepower (hp)
A unit measuring engine power. One hp was originally equal to the work output of one horse.
plough
A farm tool pulled by a tractor that turns over soil, buries weeds and prepares land for planting.
precision farming
Using GPS satellites, sensors and data to manage crops with pinpoint accuracy, reducing waste.
GPS
Global Positioning System — a network of satellites that tells a receiver exactly where it is on Earth.
threshing
Separating grain from the stalks and husks of a harvested plant. Combine harvesters do this automatically.
hectare
A unit of area equal to 10,000 square metres — roughly the size of a large supermarket car park.
autonomous
Able to operate without a human driver or pilot. Some modern tractors are fully autonomous.
