Both chisel plows and field cultivators are essential tillage tools, but each machine serves a different purpose. It is critical to understand the differences between the two to ensure you’re using exactly what you need for your field. By familiarizing yourself with all of the features of a field cultivator and chisel plow, you can choose the right tillage equipment for your soil conditions and crop cycle.
Key Takeaways
- Both chisel plows and field cultivators are pieces of tillage equipment that are pulled behind a tractor and designed for adequate field preparation.
- A chisel plow is used for primary tillage, working deeper (6-12 inches) into the soil to improve the structure and water infiltration.
- A field cultivator is used for secondary tillage, working at a shallower depth (3-5 inches), to refine the seedbed and level the topsoil.
- Chisel plows are typically used first to loosen hard, compacted soil, followed by field cultivators to prepare and aerate the soil for planting.
- Many farming operations utilize both chisel plows and field cultivators for a complete tillage system before planting.
What is a Chisel Plow?
A chisel plow is a tool used for primary tillage after a harvest. They help loosen compacted soil while still leaving crop residue on the surface. While traditional moldboard plows fully turn over the soil, a chisel plow is not built for total field inversion. It simply breaks up and loosens soil layers to improve water infiltration and manage heavy crop residue. The John Deere 2430 Chisel Plow is one example of this tool that is designed for modern farming operations.
How is a Chisel Plow Used?
The chisel plow is typically pulled by a large horsepower tractor across the field. The plow consists of double-ended shovels, also known as chisel points, that are mounted on shanks to deeply penetrate the soil. As the plow moves through the field, the points tear through the soil and stir it without pulverizing it along the way. This process helps mix residue and organic matter throughout the soil, creating the ideal conditions for planting.
When to Use a Chisel Plow:
After a harvest, chisel plows are a great tool to help loosen the soil, especially for agricultural producers who are interested in reduced-till farming or conservation efforts in order to prevent erosion.
Chisel plows are typically used:
- After harvest in the fall or spring depending on soil conditions
- In fields with compacted soil
- When managing heavy crop residue
- To aerate the soil to improve water infiltration
- As part of conservation or reduced-till farming efforts
How a Chisel Plow Impacts Soil:
A chisel plow works at deeper depths than a field cultivator, typically between 6 and 12 inches under the ground. This chisel plowing process loosens the compacted soil layers, but unlike moldboard plows, it still leaves crop residue on the surface to help reduce erosion and improve water infiltration.
What is a Field Cultivator?
A field cultivator is a tillage tool designed for secondary tillage after a harvest, typically used after a primary tillage tool, like a chisel plow. It works to disturb the top surface of the soil only by breaking up clods and incorporating residue. The result is a smooth, even, and aerated seedbed. The John Deere 2230FH Field Cultivator is one example of a field cultivator that helps agricultural professionals tend to their fields before planting season begins.
How is a Field Cultivator Used?
A field cultivator is commonly utilized with a tractor to help prep a field for planting, using shanks with shovels to further rip and aerate the soil. The field cultivator itself is typically dragged behind the tractor, and its height can usually be adjusted accordingly for soil depth. As it moves through the field, agricultural producers use this attachment to lightly work the topsoil, incorporating nutrients while also mixing and leveling the surface.
When to Use a Field Cultivator:
Agricultural producers will use a field cultivator after the primary tillage is completed, when the soil has already been loosened at the deepest levels. Field cultivators help refine the soil surface and provide a smooth, level, seedbed for planting.
Field cultivators are typically used:
- In the spring before planting
- After primary tillage has been completed (such as chisel plowing)
- When leveling the soil surface is needed
- To control small, shallow weeds
- To break up clods and aerate the soil
- To incorporate crop residue into the topsoil
How a Field Cultivator Impacts Soil:
A field cultivator works at shallow depths of 3 to 5 inches to lightly disturb the surface of the soil and incorporate crop residue. In addition to freeing up nutrients, a field cultivator can be used to remove clumps of soil, aerating it so roots have room to grow. It also eliminates weeds in the process, reducing the competition plants have to expand and thrive in the field. The result is well-conditioned, level soil that is ready for planting.
What’s the Difference Between a Chisel Plow vs. a Field Cultivator?
Chisel plows and field cultivators are both pulled behind tractors and used to prepare fields for planting. However, they have some key differences in their purpose, tillage depth, and soil results.
In general, chisel plows have heavier frames and shanks than field cultivators. This is because they are used to dig deeper into soil (6 to 12 inches) without pulverizing it along the way. As a result, chisel plows loosen hard soil layers and help improve water infiltration after a harvest.
A field cultivator, on the other hand, is specifically designed for lighter soil working as they dig into the dirt to remove clods. This is primarily because it is meant to aerate soil along the way and incorporate residue after the primary tillage has been completed. The goal of field cultivators is to create a smooth, level seedbed.
The main distinction is that chisel plows are built for deep primary tillage, while field cultivators are designed for shallow secondary tillage to refine the seedbed.

John Deere Chisel Plow vs. Field Cultivator FAQs
Which works deeper into the soil, a chisel plow or field cultivator?
A chisel plow works deeper into the soil, typically between 6 and 12 inches, to effectively mix and loosen the soil. A field cultivator operates between 3 and 5 inches into the soil and is designed for surface-level soil preparation.
Do I need both a chisel plow and a field cultivator?
In many cases, both a chisel plow and a field cultivator are used for effective tillage after a harvest. However, not every farming operation requires both. Choosing the right equipment for you depends on the goal of your tillage, soil conditions, and residue levels. It is important to understand that a field cultivator cannot replace the deep soil work of a chisel plow, and a chisel plow cannot perform the finishing work of a field cultivator.
Is a chisel plow or field cultivator better for seed preparation?
A field cultivator is better for seed preparation because it aerates and levels out the topsoil while mixing and redistributing the nutrients, creating optimal conditions for planting.
Which tool should I use first, a chisel plow or a field cultivator?
A chisel plow should be used first, as it is designed for deep primary tillage that will help break up compacted soil. This process should be followed by a field cultivator that will perform shallower, secondary tillage to prepare the seedbed for planting.
How does residue management differ between a chisel plow and a field cultivator?
A chisel plow is a primary tillage tool designed for managing heavy residue, while still leaving some on the surface. A field cultivator instead mixes the residue into the topsoil while also refining and leveling the seedbed.
Do field cultivators help with weed control?
Yes, field cultivators help control weeds by disturbing the top layer of soil and taking out weeds that were already growing. This makes field cultivation a great step to take before planting to reduce competition for nutrients in the soil.
Can a field cultivator replace a disk?
Depending on your goal and soil conditions, a field cultivator can potentially replace a disk for lighter, secondary tillage tasks like seedbed preparation. However, disks are typically better suited for managing heavy crop residue and tend to leave a rougher soil surface.
