Increased operating efficiency and less vibration, brings more performance and less fuel
consumption.
Breakers
KM SERIES
High resistance performance.
Kubota’s high-performance hydraulic KM breaker range is the reliable choice for indoor demolition and urban worksites, thanks to its weight/power ratio. The KM breakers work with low pressure and flow while delivering high performance.
Energy recovery
Breaker choice
The breaker models are designed to match Kubota's mini-excavator weight class according to
hydraulic flow /pressure and lifting capacity.
Solid design
Built for durability, these breakers are a solid body breaker.
They have a slender profile perfect for trenches and have minimum parts in movement for extended
service life.
Working tool diameter
Kubota breakers have the largest tool diameter resulting in a larger footprint -for high performance
and efficient use of hydraulic energy.
Impact rate
Kubota breakers deliver excellent weight/power ratio for an extremely high impact rate.
Tool choice
All working tools are manufactured to match Kubota breakers' design, tolerances, and performance.
The unique impact surface of the working tool is perfectly flat, transferring maximum energy
transmission to the working surface.

- Tool choice
Tool choice
- Moil point: For non-reinforced concrete. No torsion effect. Good penetration wedge effect in all directions (best in tools with small diameter)
- Chisel: For reinforced concrete. Strong torsion effect. Good penetration, optimum wedge effect in two directions
