Machines help farmers do a lot of their work.
Tractors pull other heavy machines.
Machines help to dig the soil.
They help to plant seeds and harvest the crops.
Machines milk sheep.
On farms, the farmer uses machines to help with many of the jobs that have to be done.
A tractor is used to take the farmer to different parts of the farm. The tractor is used to pull other heavy machines.
The tractor pulls a plough that digs to soil to break it up and make it ready for planting seeds.
The first ploughs were pulled by horses or oxen. The ploughs were made of wood with a metal blade to cut through the soil. Farmers in ancient Egypt used the antlers of oxen as a plough to cut and break up the soil.
After ploughing, the seeds can then be planted by the farmer using the seed drill. The seed drill plants seeds in rows and covers them over with soil. It also adds fertiliser to the soil to feed the plants and help them grow.
The seed drill is pulled by the tractor too.
Long ago seeds were planted like this. The picture on the right is of an early seed drill. The first seed drill was invented by Jethro Tull in 1700
After the seeds have grown, the crops have to be harvested. A machine called a combine harvester helps to do this. The harvester cuts the top off the plants and separates the grains of corn, wheat, sunflowers, oats from the plants. Then the machine loads the grain into a tractor trailer.
