Components:
* Moldboard: The curved, angled steel plate that cuts and lifts the soil. Its shape is designed to smoothly invert the soil, creating a furrow for planting.
* Share: The pointed, triangular piece of steel that penetrates the ground and initially breaks the soil.
* Landside: The vertical steel plate that rests against the undisturbed soil, preventing the plow from sliding sideways.
* Frame: The sturdy structure that holds the moldboard, share, and landside together.
* Beams: Strong wooden beams that connect the frame to the draft animals (or tractor).
Working Principle:
1. Penetration: The share, pulled by draft animals, cuts into the soil with its sharp point.
2. Lifting: The moldboard, angled at a specific degree, scoops the soil upward and pushes it aside, effectively inverting it.
3. Support: The landside, pressed against the undisturbed soil, provides stability and prevents the plow from moving sideways.
4. Friction: The plowing action creates friction between the plow's components and the soil. This friction helps to hold the plow in place and maintain its depth.
Key Features:
* Durable Construction: The steel components were designed to withstand the rigors of plowing, making the plow highly reliable.
* Adjustable Depth: The plow could be adjusted to different depths depending on the soil type and desired planting depth.
* Simple Design: The basic principles of its design have been used in plows for generations, demonstrating its effectiveness.
Legacy and Evolution:
While the original design has evolved over the years, the fundamental principles of the John Deere Steel Plow remain the foundation for modern plows. Its legacy continues to be celebrated as a pivotal invention in the history of agriculture.
Note:
This explanation focuses on the original John Deere Steel Plow design from 1837. Later models and other plows may have incorporated additional features or modifications.
