Breaker attachments (also known as hydraulic hammers) allow mini skid steer loaders to fracture concrete, asphalt, rock, and frozen ground in tight or confined workspaces. These compact tools provide high-impact energy using hydraulic force and are ideal for small-scale demolition, utility work, and site preparation tasks.
2. Applications
Breaking up sidewalks, driveways, patios
Trenching through rock or hard soil
Light demolition in confined areas
Breaking frozen ground for utility access
Removing small footings, curbs, or retaining walls

4. Key Components
Component
Function
Piston
Drives energy into the tool bit through hydraulic actuation
Tool Bit (Chisel/Point)
Transfer point for impact force onto the target material
Accumulator
Stores hydraulic energy and reduces pressure spikes (optional in compact models)
Housing
Encases hammer mechanism and reduces vibration/noise
Mount Frame
Connects the breaker to mini skid steer mounting plate
5. Tool Bit Options
Tool Type
Best Use Case
Moil Point
General purpose fracturing and breaking
Chisel (Flat)
Cutting along concrete or slab edges
Blunt Tool
Breaking larger rocks or compressive material
6. Operating Guidelines
6.1 Pre-Operation Setup
Attach breaker to the mini skid steer’s quick-attach plate
Connect hydraulic lines—ensure correct direction of flow and pressure rating
Confirm that breaker is primed and hydraulic system is vented
Select the correct tool bit for the material to be broken
6.2 Usage Technique
Position vertically over the target surface
Apply downward pressure without lifting the machine
Engage auxiliary hydraulics to activate the breaker
Let the tool hammer in short bursts (10–20 seconds)
Avoid dry firing (operating without contact)—this can damage internals
Reposition frequently to cover larger areas without overloading one spot
7. Safety Guidelines
Wear PPE: hard hat, safety glasses, hearing protection, gloves, and steel-toe boots
Keep all bystanders and personnel 10–15 feet away
Never operate the breaker at an angle—this stresses tool and piston
Ensure bit is in full contact before engaging hammer
Disconnect hydraulics and relieve pressure before maintenance or inspection
8. Maintenance Schedule
Task
Frequency
Inspect tool bit and retainer
Daily
Check hydraulic hoses and fittings
Daily
Grease tool bushings (if applicable)
Every 2–4 hours of use
Inspect mounting hardware
Weekly
Inspect housing and welds
Weekly
Replace tool bit if deformed
As needed
Regular greasing is critical to reduce internal wear and overheating.

10. Selection Tips
Match flow and pressure requirements to your mini skid steer’s specs Choose a pointed tool for rock or frozen ground, chisel for concrete Consider low-noise housing if working in residential areas Confirm bit retention system allows easy field replacement For frequent work, look for units with replaceable bushings and wear sleeves
