Is This Right For You?
✅ Buy if…
- You break concrete slabs, curbs, light foundations, and moderate rock on medium-frame skid steers
- General contractors who need a breaker for occasional demo work without investing in a dedicated excavator attachment
- Your machine has 40-70 HP and standard hydraulic flow — medium breakers are sized for that range
⛔ Skip if…
- Heavy reinforced concrete or large rock is your primary target — a heavy-duty breaker gets the job done faster
- You're only doing light demolition on small machines — a compact breaker is sufficient and lighter
🔍 Also consider…
- Heavy-duty hydraulic breaker for larger machines and harder material
- Light-duty breaker if your machine is compact and work is occasional
🔧 Machine Compatibility
Compatible with all skid steer brands and compact track loaders via universal SSQA quick attach. Mid-frame machines (S450–S650 class) are the most common fit.

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
How to Connect
- Attach breaker using Bob-Tach
- Connect single aux hydraulic circuit (breakers use one-way flow)
- Set machine to single-action aux mode if available
- Run 5 seconds at idle before working to allow oil to circulate
⚠ Safety NoteBreakers use single-direction flow. Do not run breaker in same position for more than 30 seconds — move to avoid blank-firing damage.
⚒️ Before You Buy a Hydraulic Breaker
Breaker sizing and hydraulic matching are critical — an oversized or underpowered breaker wears out faster and can damage your machine.
- Size the breaker class to your machine's rated operating capacity (ROC) Breaker sizing guide →
- Verify your machine's GPM and PSI output match the breaker's requirement Hydraulic flow guide →
- Confirm anti-blank-fire protection — protects both the breaker and your machine

Confirm Machine Fit
Verify your machine's hydraulic flow meets this attachment's requirements before ordering. High-flow attachments need 25–45+ GPM — standard flow machines won't run them properly.
