A plow is an essential agricultural implement used to break up the soil, turn it over, and create furrows or ridges for planting seeds or crops. Plows have been used for centuries and have undergone significant advancements over time, from simple digging sticks to modern tractor-drawn plows.
Key Facts
- Purpose: The primary purpose of a plow is to break up the soil, turn it over, and create furrows or ridges for planting seeds or crops.
- Types of Plows: There are various types of plows, including moldboard plows, disk plows, chisel plows, and rotary plows. Each type has its own design and functionality, suited for different soil conditions and farming practices.
- Components: A plow typically consists of several components:
- Share: The share is the blade or cutting edge of the plow that cuts through the soil.
- Moldboard: The moldboard is a curved metal plate that turns the soil slice cut by the share, effectively flipping it over.
- Landside: The landside is a plate on the opposite side of the moldboard that absorbs the side thrust of the turning action.
- Frame: The frame provides support and stability to the plow.
- Power Source: Traditionally, plows were drawn by oxen or horses. However, in modern farming, plows are usually drawn by tractors, which provide more power and efficiency.
- Operation: When the plow is pulled forward, the share cuts into the soil, and the moldboard turns the soil slice over, burying weeds and crop residues. This process helps to break up compacted soil, improve drainage, and create a suitable seedbed for planting.
Types of Plows
There are various types of plows, each designed for specific soil conditions and farming practices. Some common types of plows include:
- Moldboard Plows: These are the most common type of plow, consisting of a share, moldboard, and landside. The share cuts through the soil, the moldboard turns the soil slice over, and the landside absorbs the side thrust of the turning action.
- Disk Plows: Disk plows have individually mounted concave disks that are inclined backward to achieve maximum depth. They are particularly suitable for hard, dry soils, shrubby or bushy land, or rocky land.
- Chisel Plows: Chisel plows are used for deep tillage to break up hardpan and packed soils. They have rigid or spring-toothed shanks with double-pointed shovels mounted on a transverse bar.
- Rotary Plows: Rotary plows, also known as tillers, have curved cutting knives mounted on a horizontal power-driven shaft. They are used for seedbed and weed control and work well at high speeds.

Power Source
Traditionally, plows were drawn by oxen or horses. However, in modern farming, plows are usually drawn by tractors, which provide more power and efficiency. Tractors can pull multiple plows simultaneously, increasing productivity and reducing labor requirements.
Operation
When the plow is pulled forward, the share cuts into the soil, and the moldboard turns the soil slice over, burying weeds and crop residues. This process helps to break up compacted soil, improve drainage, and create a suitable seedbed for planting. The depth of plowing can be adjusted by changing the angle of the plow or the tractor’s speed.
Plows play a crucial role in agriculture by preparing the soil for planting, improving soil structure, and managing weeds. Advances in plow design and the use of tractors have significantly increased the efficiency and productivity of farming operations.
FAQs
What is the primary purpose of a plow?
The primary purpose of a plow is to break up the soil, turn it over, and create furrows or ridges for planting seeds or crops. Plowing helps to improve soil structure, manage weeds, and create a suitable seedbed for planting.

The main components of a plow include the share, moldboard, landside, and frame. The share cuts through the soil, the moldboard turns the soil slice over, the landside absorbs the side thrust of the turning action, and the frame provides support and stability to the plow.
How does a plow work?
When the plow is pulled forward by a tractor, the share cuts into the soil, and the moldboard turns the soil slice over, burying weeds and crop residues. This process helps to break up compacted soil, improve drainage, and create a suitable seedbed for planting.
What are the different types of plows?
There are various types of plows, including moldboard plows, disk plows, chisel plows, and rotary plows. Each type has its own design and functionality, suited for different soil conditions and farming practices.
What is the power source for a plow?
Traditionally, plows were drawn by oxen or horses. However, in modern farming, plows are usually drawn by tractors, which provide more power and efficiency. Tractors can pull multiple plows simultaneously, increasing productivity and reducing labor requirements.
How deep does a plow go?
The depth of plowing can be adjusted by changing the angle of the plow or the tractor’s speed. Plowing depth can vary from shallow to a half meter (1.5 feet) or more, depending on the soil conditions and the type of crop being planted.
What are the benefits of using a plow?
Using a plow has several benefits, including breaking up compacted soil, improving drainage, managing weeds, incorporating crop residues, and creating a suitable seedbed for planting. Plowing also helps to control erosion and improve soil health.
What are some modern advancements in plow technology?
Modern advancements in plow technology include the use of GPS and laser guidance systems for precision plowing, variable-depth plowing to optimize soil conditions, and the development of specialized plows for specific soil types and farming practices.
