Breaking up concrete can feel like a monumental task, especially for DIYers and first-time renovators. You might be looking at a stubborn slab, an old patio, or a foundation that needs to come out, and wondering how to get the job done without breaking your back or your budget. The good news is, with the right tools and a little know-how, you can make short work of even the toughest concrete. A skid steer equipped with a jackhammer attachment is a powerful combination that can transform your demolition project. We’re here to walk you through exactly how to use this formidable tool safely and efficiently, so you can get started on your next project with peace of mind.
Why Use a Jackhammer Attachment on a Skid Steer?
When you’re facing a large concrete job, a handheld jackhammer can be exhausting and slow. That’s where a skid steer-mounted jackhammer attachment shines. It leverages the power and stability of the skid steer, allowing you to break up concrete much faster and with less physical strain. Think of it as supercharging your demolition efforts. This setup is ideal for:
- Removing large concrete slabs for driveways or patios.
- Demolishing foundations or old structures.
- Breaking up rock or hard-packed earth.
- Clearing sites for new construction or landscaping.
Using a skid steer attachment means you’re not holding the vibrating tool yourself, significantly reducing fatigue and the risk of Hand-Arm Vibration Syndrome (HAVS), a condition that can cause long-term nerve and blood vessel damage. For serious demolition work, it’s a game-changer.
Understanding Your Skid Steer Jackhammer Attachment
Before you start, it’s crucial to understand the basic components of your skid steer jackhammer setup. Most attachments will include:
- The Jackhammer Hammer: This is the part that actually strikes and breaks the concrete. It’s powered by the skid steer’s hydraulic system.
- The Moil Point or Chisel Bit: This is the sharp, pointed, or chisel-shaped tool that attaches to the hammer. The moil point is best for general breaking, while a chisel bit is good for cutting or breaking along lines.
- Hydraulic Hoses: These connect the jackhammer attachment to your skid steer’s hydraulic ports.
- Mounting System: This is how the attachment connects to your skid steer’s loader arms.
The power for the jackhammer comes from your skid steer’s hydraulic pump. The stronger your skid steer’s hydraulic flow and pressure, the more effective your jackhammer will be. It’s important to ensure your skid steer meets the hydraulic requirements of the jackhammer attachment. You can usually find this information in the owner’s manuals for both your skid steer and the attachment.
Essential Safety Gear: Don’t Skip This!
Safety is paramount when operating any heavy machinery, especially with a powerful demolition tool like a jackhammer. Always wear the following:
- Hard Hat: Protects against falling debris.
- Safety Glasses or Goggles: Essential to keep dust and flying fragments out of your eyes.
- Hearing Protection: Earplugs or earmuffs are a must, as jackhammers are incredibly loud.
- Steel-Toed Boots: Protect your feet from dropped tools or heavy materials.
- Heavy-Duty Gloves: Provide grip and protect your hands.
- High-Visibility Vest: Makes you more visible to others on the job site.
- Dust Mask or Respirator: Crucial for protecting your lungs from concrete dust, which can contain silica. The Occupational Safety and Health Administration (OSHA) provides guidelines on silica exposure and control measures.
Never operate the equipment without the proper safety gear. It’s better to be overprepared than to risk injury.
Step-by-Step Guide: How to Use a Jackhammer on a Skid Steer
Ready to get started? Follow these steps carefully:
Step 1: Inspect Your Skid Steer and Attachment
Before you even start the engine, give everything a thorough once-over.
- Check Tires/Tracks: Ensure they are in good condition and properly inflated (if applicable).
- Inspect Hydraulic Fluid: Check the level and look for any leaks in the lines or fittings.
- Examine the Jackhammer Attachment: Make sure the bit is securely in place and not excessively worn. Check the hoses for any damage or leaks.
- Verify Skid Steer Hydraulics: Ensure your skid steer’s hydraulic system is functioning correctly and can provide the necessary flow and pressure for the jackhammer. Consult your skid steer’s manual for specifications.
Step 2: Attach the Jackhammer to Your Skid Steer
This process can vary slightly depending on your skid steer model and the attachment’s mounting system, but here’s the general idea:
- Position the Skid Steer: Back your skid steer up to the attachment, aligning the loader arms with the attachment’s mounting bracket.
- Lower the Loader Arms: Carefully lower the loader arms until they are level with the attachment’s mounting points.
- Connect the Mount: Engage the locking pins or mechanisms that secure the attachment to the loader arms. Ensure they are fully locked.
- Connect Hydraulic Hoses: Locate the hydraulic quick-connect fittings on your skid steer and the jackhammer attachment. Connect the hoses, ensuring they are securely seated. It’s crucial to connect the pressure hose to the correct port and the return hose to the other. Typically, one hose provides pressurized hydraulic fluid to operate the hammer, and the other returns the fluid to the tank. Refer to your attachment’s manual for specific connection details.
Pro Tip: Many modern skid steers have universal quick-attach systems that make this process much simpler. Always ensure the attachment is securely locked before proceeding.
Step 3: Prepare the Work Area
Clear the area where you’ll be working.
- Remove Obstacles: Get rid of any loose debris, rocks, or objects that could interfere with the jackhammer or become projectiles.
- Mark Utilities: If you are unsure about underground utilities, call your local utility locating service (like 811 in the US) before you start digging or breaking concrete. This is a critical safety step.
- Consider Water: Sometimes, spraying the concrete with water can help reduce dust, though it can also make the area muddy.
Step 4: Start the Skid Steer and Engage Hydraulics
Now it’s time to power up.
- Start the Engine: Start your skid steer’s engine.
- Engage Auxiliary Hydraulics: Most skid steers have a switch or lever to engage the auxiliary hydraulic system. This system powers the attachment.
- Test Controls: Gently move the joystick or controls that operate the jackhammer attachment to ensure it’s responding correctly. You should feel the hydraulic system engage.
Step 5: Position the Jackhammer for Breaking
This is where you’ll start the actual demolition.
- Lower the Attachment: Use your skid steer’s controls to carefully lower the jackhammer attachment until the bit is resting on the concrete surface.
- Position for Impact: Aim the bit at the spot where you want to begin breaking. It’s often best to start at an edge or a crack if possible.
- Apply Downward Pressure: Gently use the skid steer’s lift and tilt functions to apply consistent downward pressure on the jackhammer. You don’t need to force it; let the hammer’s power do the work. The weight of the skid steer and the hydraulic force are what drive the bit into the concrete.
Step 6: Operate the Jackhammer
Time to break some concrete!
- Activate the Hammer: Use the auxiliary hydraulic control (often a button on the joystick or a separate lever) to activate the jackhammer.
- Maintain Control: Keep the skid steer steady. The jackhammer will vibrate, so smooth movements are key. Avoid jerky motions.
- Work in Sections: Don’t try to break up the entire slab at once. Work in small, manageable sections. Move the jackhammer across the concrete, creating cracks and breaking it into smaller pieces.
- Adjust Angle: You may need to slightly adjust the angle of the jackhammer to find the most effective breaking point.
- Clear Debris: Periodically use the skid steer’s bucket or forks to clear away broken concrete pieces. This helps you see your work area and prevents material from piling up.
Important Note on Bit Wear: Bits wear down over time. If you notice the jackhammer is no longer breaking concrete effectively, it’s likely time to replace the bit. Worn bits can reduce efficiency and potentially damage the hammer mechanism.
Step 7: Moving and Breaking
As you break sections, you’ll need to move the skid steer.
- Reposition the Skid Steer: Once a section is broken up, lift the jackhammer slightly, move the skid steer to the next section, and lower the attachment again.
- Work Systematically: Develop a pattern for breaking the concrete. Working from one edge and moving across the area is usually the most efficient method.
- Break into Manageable Chunks: Aim to break the concrete into pieces that your skid steer can easily lift and move.
Step 8: Disconnecting the Jackhammer Attachment
Once the job is done, you’ll need to safely remove the attachment.
- Lower the Attachment: Lower the jackhammer attachment to the ground on a stable, level surface.
- Turn Off the Skid Steer: Shut down the skid steer’s engine.
- Relieve Hydraulic Pressure: It’s good practice to cycle the auxiliary hydraulic controls a few times after the engine is off to relieve any residual pressure in the lines.
- Disconnect Hydraulic Hoses: Carefully disconnect the hydraulic hoses. Be prepared for a small amount of hydraulic fluid to drip. Use a rag to wipe any spills.
- Release Locking Pins: Disengage the locking pins or mechanisms that secure the attachment to the loader arms.
- Back Away Slowly: Slowly back the skid steer away from the attachment.
Choosing the Right Jackhammer Bit
The type of bit you use can significantly impact your work. Here’s a quick rundown:
| Bit Type | Best For | Description |
|---|---|---|
| Moil Point | General breaking, cracking concrete, breaking up hard soil/rock | A pointed, conical tip that focuses impact energy into a small area, ideal for shattering materials. |
| Chisel/Flat Bit | Breaking concrete along lines, prying up slabs, cutting trenches | A flat or beveled edge that can be used for more controlled breaking or to sever rebar. |
| Asphalt Cutter | Breaking up asphalt | A wider, often curved blade designed for slicing through asphalt. |
For most concrete demolition, the moil point is the go-to choice. If you need to break concrete along a specific line or cut through rebar, a chisel bit might be more appropriate.
Skid Steer Jackhammer Attachment vs. Handheld Jackhammer
It’s helpful to compare the two options:
| Feature | Skid Steer Jackhammer Attachment | Handheld Jackhammer |
|---|---|---|
| Power Source | Skid Steer Hydraulics | Electric or Pneumatic (Air Compressor) |
| Operator Fatigue | Very Low (Skid steer operator) | High (Direct handling) |
| Breaking Speed | Much Faster | Slower |
| Portability | Limited to skid steer access | High (Can be used in tight spaces) |
| Cost | Higher initial investment (attachment cost) | Lower initial investment |
| Dust Control | Can be managed with water spray | Can be managed with water or dust suppression systems |
| Vibration Exposure | Minimal to operator | High to operator (risk of HAVS) |
The skid steer attachment is generally preferred for larger, more demanding jobs where speed and operator comfort are priorities. Handheld jackhammers are better suited for smaller tasks or areas inaccessible to a skid steer.

- Ensure the bit is sharp and properly seated.
- Check for loose mounting hardware.
- A worn or damaged jackhammer mechanism could be the cause.
If you suspect a mechanical issue with the jackhammer itself, consult the manufacturer’s manual or a qualified technician.
Frequently Asked Questions (FAQ)
Q1: How much power does a skid steer need to run a jackhammer attachment?
A1: The hydraulic requirements vary by jackhammer model. Generally, you’ll need a skid steer with a good hydraulic flow rate (gallons per minute, GPM) and sufficient hydraulic pressure (PSI). Always check the specifications for your specific jackhammer attachment and ensure your skid steer meets or exceeds them. You can find this information in your owner’s manuals.
Q2: Can I use a standard skid steer bucket to move the broken concrete?
A2: Yes, absolutely! Once the concrete is broken into manageable pieces, a standard skid steer bucket is the ideal tool for loading and hauling it away. You might even use the bucket to help pry up larger chunks after they’ve been fractured by the jackhammer.
Q3: How do I know when to replace the jackhammer bit?
A3: You’ll notice a significant decrease in breaking efficiency. The bit will appear blunted or rounded instead of sharp. Continuing to use a worn bit can put extra strain on the jackhammer mechanism and reduce productivity. Inspect the bit regularly.
Q4: Is it safe to operate a jackhammer attachment in wet conditions?
A4: Yes, but with caution. Water can help suppress dust, but it can also make the ground slippery and reduce traction for your skid steer. Ensure you have good footing and operate at a slower, more controlled pace. Be mindful of electrical hazards if your skid steer or attachment has any electrical components.
Q5: What’s the difference between a moil point and a chisel bit?
A5: A moil point is pointed and designed for shattering concrete and rock. A chisel bit has a flat, sharp edge and is better for breaking along lines, cutting through rebar, or prying. For general demolition, the moil point is usually the best choice.
Q6: How much concrete can I break in a day?
A6: This depends heavily on the thickness and strength of the concrete, the power of your skid steer and jackhammer, the type of bit you’re using, and the operator’s experience. A skid steer jackhammer is significantly faster than a handheld one, allowing you to break up much larger areas in a single day.
