What is a Chisel Plow Shank?

A chisel plow shank is a key component of a chisel plow, an agricultural implement used for deep tillage. The primary purpose of a chisel plow shank is to break up and aerate the soil without turning it over, maintaining the topsoil structure while alleviating compaction and promoting root growth.

Key Features:

  • Chisel plow shanks are robust, typically made from high-strength steel to withstand the stresses of deep tillage. They are mounted on a main frame, usually in rows, and penetrate the soil vertically.
  • The shanks are designed to break up hardpan and compacted soil layers, improving water infiltration and root penetration. Unlike moldboard plows, chisel plow shanks leave crop residues on the surface, reducing erosion and promoting organic matter retention.
  • They typically work at depths ranging from 6 to 16 inches, depending on the soil conditions and the specific agricultural needs. This deep tillage helps prepare the soil for planting without excessive disruption.
  • Chisel plow shanks can be equipped with various attachments, such as sweeps, spikes, or points, to enhance their effectiveness in different soil types and crop conditions.

A distinctive feature of a chisel plow is its ability to loosen the soil without deforming the top layer. This equipment is used for vertical soil tillage, which has become widespread in Canada.

The shank supports all additional mechanisms that have direct contact with the soil, such as the sweep (if the plow is of the sweep type), the plow points (the actual cutting parts), and the plow blades.

Before choosing a chisel plow for sale, decide on its type. You have a choice: a mounted plow or a trailed plow. The working width of trailed plows is somewhat larger. Always consider having spare parts for the plow, especially the shank, which is actively used and thus wears out easily! The tines of the chisel plow should be made of high-strength steel that does not deform or wear out during operation. Available are chisel plow shanks and all other parts you need when working with a small chisel plow, a universal plow, or a 3-point plow.

Types of Chisel Plow Shanks

Rigid Shanks:

  • Description: These shanks are fixed in position and do not have any spring mechanism. They are very robust and suitable for heavy-duty tillage in conditions with fewer obstacles.
  • Advantages: Provide consistent depth and are less prone to wear and tear due to fewer moving parts.
  • Usage: Ideal for deep tillage in fields with minimal rocks or underground obstructions.

Rigid Shanks

Spring-Trip Shanks:

  • Description: Equipped with a spring mechanism that allows the shank to trip backward when encountering an obstacle and then reset to its working position.
  • Advantages: Protects the plow and shank from damage, allowing for use in fields with rocks and other obstructions.
  • Usage: Suitable for varied soil conditions, especially in fields with known obstructions.

Spring-Trip Shanks

Curved Shanks:

  • Description: These shanks are curved, providing additional strength and better handling of soil flow and residue.
  • Advantages: Improved residue flow and reduced soil disturbance compared to straight shanks.
  • Usage: Often used in conservation tillage systems where maintaining residue cover is important.

Curved Shanks:

Edge-Bent Shanks:

  • Description: These shanks are bent so that the narrow dimension faces forward on the bottom half, which enhances strength and reduces soil impact.
  • Advantages: Provides better penetration and less soil disturbance, making them suitable for high-residue fields.
  • Usage: Effective in heavy residue conditions and for deep tillage.

Edge-Bent Shanks

Straight Shanks:

  • Description: As the name implies, these shanks are straight and provide uniform soil penetration.
  • Advantages: Simple design and effective for deep tillage with consistent results.
  • Usage: Ideal for uniform soil conditions and fields with minimal residue.

Advantages of Using Chisel Plow Shanks

With the purchase of a chisel plow, you gain new soil tillage quality:

  • Soil Health: By breaking up compacted layers, chisel plow shanks improve soil aeration and water movement, fostering healthier root systems and better crop yields.
  • Erosion Control: The minimal soil disturbance and retention of crop residues help reduce erosion and maintain soil structure.
  • Versatility: Chisel plow shanks can be used in various soil conditions, making them a versatile tool for many farming operations.

It is essential to choose the plow correctly based on the type of soil. Some might need a model for deep loosening, others for effectively breaking clods and compacted layers. It is advisable to consult a specialist about this.
