Compact Hydraulic Breakers

Montabert® SD hydraulic breakers are designed for use on skid-steer loaders, backhoe loaders, and mini and mid-size excavators. The SD-Series provides the versatility and productivity to accomplish multiple tasks with a single carrier, a single operator, and a single attachment.

Compact Benefits

  • Maintenance and overhaul are quick and easy because of fewer wear parts and no tie rods; bushing, pins, and tools can easily be replaced in the field without removing the breaker from the carrier (excluding SC-50)
  • Fully enclosed, soundproof cradle reduces vibrations transferred to the carrier and limits noise on the worksite
  • Lightweight, heavy-duty housing protects working parts and hoses
  • A multi-tool is included to easily service the breaker and check wear limits (excluding SC-50)
  • Tolerates high back pressures to allow fit-up to a wide range of carriers
  • Energy chamber acts as hydraulic shock absorber and reduces pressure variations in the hydraulic circuits to provide consistent energy to the breaker

SD-22, SD-28, SD-36, & SD-42

  • Internally mounted retaining pin clip makes tool change out even easier, with no special tools required


  • Two strong retaining pins and locks keep tool and bushing in place
  • Optional air pressurization kit for underwater applications and autolube greasing system
