6 Best Tractor Subsoilers For Breaking Hardpan That Revive Tired Soil
Break through tough hardpan with a top-rated subsoiler. We review the 6 best models designed to improve drainage, aeration, and overall soil health.
You’ve done everything right in your pasture or garden plot—amended the soil, rotated crops, managed grazing—but you’re still seeing standing water after a rain and your plants look stunted. You dig down a foot and hit a layer of soil that’s as hard as a brick. This is hardpan, and it’s choking the life out of your land by preventing water and roots from going where they need to.

What is Hardpan and Why a Subsoiler is Key
Hardpan is a dense, compacted layer of soil that forms below the normal tillage depth. It’s created by the repeated weight of tractors, the smearing action of a rototiller’s tines, or even heavy animal traffic on wet ground. This impermeable layer acts like a concrete floor beneath your topsoil, stopping water from draining and blocking plant roots from accessing deeper moisture and nutrients.
A subsoiler, sometimes called a ripper, is the specific tool designed to fix this problem. It’s a simple, powerful implement with one or more long, heavy-duty steel shanks. Unlike a plow or tiller that inverts and mixes the topsoil, a subsoiler slices deep into the ground—typically 12 to 24 inches—and fractures that hardpan layer from below.
The goal isn’t to bring that poor subsoil to the surface, but to shatter the compaction in place. This creates vertical fissures that allow water to drain, air to penetrate, and roots to explore new depths. It’s a foundational step in soil remediation that can dramatically improve the health and productivity of a piece of land with just a few passes.
King Kutter SS-1-HD: A Versatile Single Shank
For most hobby farmers with a compact or small utility tractor, the King Kutter single-shank subsoiler is a fantastic starting point. It’s a well-built, no-nonsense tool from a reputable brand that you can find at many farm supply stores. It’s heavy enough to do the job but not so overbuilt that it requires a huge tractor.
The SS-1-HD (Heavy Duty) model is particularly useful because it strikes a great balance between strength and affordability. It features a solid steel shank with a replaceable, hardened tip—a crucial feature, as that point takes a tremendous amount of abuse. This implement is perfect for breaking up compaction in a 1-acre market garden, prepping a food plot for deer, or improving drainage in a small, waterlogged pasture.
Think of the King Kutter as the reliable workhorse of the subsoiler world. It’s not the fanciest or the heaviest, but it consistently gets the job done for a wide range of common hardpan issues. It’s a smart investment that will pay dividends in soil health for years to come.
CountyLine Subsoiler: The Affordable Hardpan Buster
If you only need to tackle compaction every few years or have a smaller area to cover, the CountyLine subsoiler is a very practical choice. Sold primarily through Tractor Supply Co., it’s one of the most accessible and affordable options on the market. This makes it a low-risk entry point for someone who needs to solve a problem without investing heavily in a specialized implement.
The main tradeoff here is build quality versus price. It’s not going to have the same thick steel or heavy-duty welds as a premium brand. But for a 25-horsepower compact tractor pulling through moderately compacted loam, it’s often more than enough tool for the job. Why pay twice as much for a tool you’ll only use for a few hours every third season?
This subsoiler is ideal for the hobby farmer who needs to break up the plow pan in their half-acre garden or slice a few drainage lines through a soggy patch in the yard. It proves that you don’t always need the heaviest, most expensive tool to get a great result. For occasional use, its value is hard to beat.
Titan 3-Point Ripper for Tougher Compaction Jobs
When you’re dealing with seriously compacted ground, you need more steel. Titan Attachments is known for offering heavy-duty implements at aggressive prices, and their 3-point ripper is a great example. This is a step up in weight and durability from entry-level models.
These rippers often feature a much thicker shank and a more robust A-frame, designed to handle the immense force required to break through rock-hard clay or ground that’s been abused for years. If you’ve just acquired property that was once a logging road or a gravel parking area, this is the kind of tool you’ll need to begin the reclamation process.
The extra weight is a key advantage, as it helps the shank penetrate and stay in the ground without riding up over tough spots. Just be sure your tractor is up to the task. This tool is best suited for utility tractors in the 40+ horsepower range that have the weight and traction to put its strength to good use.
Woods S106: Heavy-Duty Single Shank Performance
Woods is a name that stands for quality and longevity in the farm equipment world. Their S106 single-shank subsoiler is the "buy it for life" option. The initial cost is higher, but you’re paying for superior engineering, top-grade steel, and welds that are built to withstand decades of hard work.
This isn’t just about being heavier; it’s about being smarter. The shank is designed for maximum fracture with minimal surface disturbance, and the overall construction is meant for someone who considers subsoiling a regular part of their land management practice, not just a one-time fix. It’s built to handle rocky soils and tough conditions without flinching.
Choosing the Woods S106 is an investment in efficiency and reliability. For the serious hobby farmer managing multiple pastures, rotating through several large garden plots, or running a small-scale hay operation, the durability justifies the cost. It’s the kind of tool you can use hard, put away wet, and pass down to the next generation.
Land Pride SS15: Compact Tractor Subsoiling Power
Owners of subcompact and smaller compact tractors often face a dilemma: many implements are simply too big and heavy for their machines. Land Pride, a company known for building attachments that are perfectly matched to smaller tractors, solves this with their SS15 series. These subsoilers are engineered to be effective without demanding excessive horsepower or weight.
The SS15 is designed with the limitations of a 25-35 HP tractor in mind. The shank angle and overall weight are optimized to allow for deep penetration without overwhelming the tractor’s hydraulic lift or pulling power. This means you can actually use the tool to its full potential instead of struggling to get it in the ground.
This is the perfect choice for breaking up hardpan in raised bed gardens, aerating soil between rows of young trees in a small orchard, or improving a compact lawn area before reseeding. It’s a prime example of matching the implement to the tractor, not the other way around.
Everything Attachments Ripper with Coulter Wheel
For those looking to subsoil an existing pasture or a field with a cover crop, the standard shank can cause a lot of unwanted surface damage, tearing up valuable sod. The Ripper from Everything Attachments offers a fantastic solution: an integrated coulter wheel. This sharp, rolling disc is mounted in front of the shank.
The coulter’s job is to slice cleanly through the turf and surface debris before the shank gets there. This creates a neat incision, allowing the ripper shank to pass through with significantly less tearing and disruption of the topsoil and plant life. The result is fractured hardpan below with a nearly undisturbed surface above.
This feature is a game-changer for regenerative practices. You can relieve compaction and improve water infiltration in your hayfield without having to reseed it, or break up hardpan in a no-till garden bed while leaving your cover crop mulch largely intact. It’s a specialized feature that solves a very common and important problem.
Matching Shank Depth and HP to Your Tractor Needs
Buying a subsoiler isn’t just about picking a brand; it’s about matching the tool to your tractor and your soil. A common mistake is buying an implement that’s too big for your machine. Power is useless without traction, and a 30 HP tractor will just spin its wheels trying to pull a massive ripper designed for an 80 HP machine.
A good rule of thumb is to plan for 10 to 15 horsepower per foot of depth for a single shank. This can vary wildly with soil type—sandy loam is much easier to pull through than dense, wet clay. A 40 HP tractor might pull a single shank 20 inches deep in ideal soil, but struggle to reach 14 inches in tough conditions.
Before you buy, follow these steps:
- Dig a test hole. Find out exactly how deep your hardpan layer is. There’s no sense in buying a 24-inch subsoiler if your compaction is only 12 inches down.
- Be realistic about your tractor. Consider its drawbar horsepower, its total weight, and whether you have 4-wheel drive. Weight and traction are just as important as engine power.
- Prioritize effective depth. It is far better to buy a smaller subsoiler that your tractor can pull easily at the target depth than a larger one that it can only scratch the surface with. Sometimes, two shallower passes are more effective than one failed deep pass.
A subsoiler is one of the most transformative tools a landowner can own, turning compacted, unproductive ground into a healthy, thriving ecosystem. It’s not an every-season implement, but by choosing the right one for your tractor and your land, you’re making a powerful, long-term investment in the foundation of everything you grow.
