A seed drill is an agricultural tool that can be used to plant the seeds for a crop. Seed drills help sow the seeds by measuring them and planting them at the right depth and distance in the soil. Birds can’t get to the seeds because the dirt is piled on top of them at the same height. Using agricultural seed drills to plant seeds could increase crop yields and save money on labor.

When a seed drill is used, the average crop yield may go up by a large amount. Farmers can use no-till planters, just seed-distribution drills, to plant seeds without disturbing the soil. In the idea, a device is made to take seeds out of a seedbox and plant them vertically through a tube. Disc seed drills can be used to do more than just plant seeds. They can also be used to spread fertilizer evenly across fields.

Elemental Part of a Seed Drill

A mechanical seed metering system seed drill needs the following parts to work right:

1. The frame
2. The seedbox
3. The seed metering mechanism
4. The furrow openers
5. The covering device
6. The transport wheels

• Frame 

The frame of a seed drill is usually made of angle iron and a cover to protect it. The frame is made to be able to handle the different loads that are present during normal operation.

• Seedbox

It can be made out of galvanized iron or sheets of mild steel with the right coating. Sometimes, a small agitator is put in to keep the seeds from sticking together.

• Protective covering

It is used to fill a furrow after a crop has been planted. A Patti, chains, drag, packers, rollers, or press wheels can be used to cover the seeds. In terms of size and shape, they come in many different kinds.

• Wheel Transport

The main axle has two wheels on it. Some seed drills even have tires that are filled with air. The wheels have attachments that let them send energy to the part of the machine that makes the seeds fall.

Why is a seed drill called a fertilizer drill?

Attachments on seed drills that drop fertilizer ensure that fertilizer is spread evenly across the field. A seed cum fertilizer drill is the name of the machine. In this type of drill, the large seed box is split down the middle so the seeds and nutrients can be kept separate. I. A bullock can pull a seed drill. II. A tractor can pull a seed drill.

Seed Drill Advantages

• Slower and slower people plant seeds.
• In addition, drilling makes it easier to thin or rough up sick or otherwise deficient plants. Learning to use weeding tools like the wheel hoe, the Japanese rice weeder, and others don’t take long to get rid of weeds.
• When crops are drilled, activities like earthing up, manuring, irrigation, and spraying can be done between them.
• The space between the drilled crops is the same, so they all get the same amount of light, air, and food.
• Harvesting crops is more convenient and helpful. So, the cost of picking crops goes down.
• Drilling can be useful for both single-crop and intercropping. 6. The cost of growing a crop that has been drilled goes down, and the crop’s yield goes up.

Seed drill disadvantages

• Drilling requires using a tool like a seed drill, which adds to the cost of farming. For drilling, more work, resources, and money are needed.
• To use a seed drill, you need to be an expert who has been trained.
• When you compare the two methods, drilling takes more time than broadcasting. When the ground is too rocky or has too much clay, drilling is not possible.
