Hits hard! Had a toro breaker on my mini skid steer that was built way cheaper than this one. It comes with a rebuild seal kit, extra bit, and recharge tank! Works great!

Best addition to our fleet this year. If you do any kind of small-scale demolition or utility work, this 300ft-lbs breaker is worth every penny. Fast, efficient, and very reliable.

This 300ft-lbs hammer packs a serious punch. I used it to break up a 4-inch thick reinforced concrete driveway, and it cracked through it like it was nothing. Exceptional power for a compact attachment.

I love the simple design. Fewer moving parts mean fewer things to break. We've put it through 40 hours of heavy use this month and haven't had a single issue or need for repairs.

I use this for removing old concrete footings and boulders in residential backyards. It fits through standard garden gates and gives me the breaking power I need without destroying the customer's lawn with a massive machine.

We had a demolition job in a narrow alleyway where a full-size skid steer couldn't fit. This breaker paired with our mini loader was the only way to get the job done. It's a lifesaver for confined spaces.

The hook-up was incredibly simple. The hydraulic response is very snappy and easy to control from the operator station. It feels like a natural extension of the skid steer's own power system.

What impressed me most was the consistency. The hydraulic flow is perfectly tuned so the hammer doesn't skip or hesitate. It delivers strong, steady impacts that make quick work of old asphalt and rock.

The steel casing is heavy-duty and the moil point is high-quality. It shows very little wear even after pounding through some seriously hard rock. A great investment for any utility contractor.

I've used larger breakers on full-size excavators, and this mini version holds its own for residential work. It's efficient, powerful, and significantly increased our productivity on-site.

For a breaker, this unit runs surprisingly smooth. The hydraulic dampening seems well-engineered, so I'm not getting rattled to death in the operator stand while breaking up frozen ground.
