Is This Right For You?

Buy if

You break large reinforced concrete foundations, thick rock, or concrete retaining walls regularly
Your skid steer is a large-frame machine (80+ HP) rated for a heavy hammer attachment
Production rate matters — heavy-duty breakers complete demolition jobs significantly faster than medium class

Skip if

Your machine is medium-frame or smaller — a heavy breaker can exceed carrier weight class limits and damage hydraulics
Occasional light demolition is your only use — a medium-duty breaker handles that range at lower cost

Also consider

Medium-duty hydraulic breaker for smaller machines and occasional demolition
Light-duty breaker for compact machines doing concrete curb or small slab work

Machine Compatibility

Best suited to large-frame machines (S750+ class or equivalent CTL). Verify your machine's rated operating capacity (ROC) before ordering.

Care & Maintenance

Check nitrogen buffer gas pressure at the start of every season and whenever impact energy feels reduced — low gas pressure is the most common cause of reduced performance
Lubricate the tool (chisel) bushing and retainer pins before every use — dry bushings accelerate side-loading wear on both the bushing and the tool shank
Inspect the lower bushing for wear after every 40 hours — a worn bushing allows chisel wobble, reducing impact energy delivery and accelerating shank wear
Never blank-fire the breaker — operating without material contact destroys the internal valve in minutes; this is the most common cause of breaker failures
Verify return-line back-pressure annually — back-pressure exceeding the breaker's rated limit destroys the valve seal progressively and may not be immediately obvious
