  • Couplings are machined and sized for the high-flow performance required by hydromechanical attachments.
  • Better hydraulic flow results in fuel efficiency gains from reduced back pressure.
  • Enclosed spring prevents contamination of hydraulic system.
  • Durable and reliable fluid connections create a system for hydraulic fluid flow and no opportunity for spills during tool exchange.
  • Internally routed hoses in the bracket and coupler use fewer external hoses, reducing overall hose and repair costs.

  • Changing attachments with hydraulic connecting couplers is 98% faster than pin-on.
  • Using hydraulic connect couplers instead of mechanical couplers saves 96% time in changing attachments.
  • Quick disconnect design improves lifespan and is easy to service.
  • Design of cover lid and sealing adds protection for couplings and prevents contamination to hydraulic system.
  • Machined position of the quick disconnect valves on the tool and on the bracket ensure a tight and reliable connection limiting chance of leaks or damage.
  • Quick disconnect couplings are installed in the same direction as the locking force with a solid flange to ensure a solid fit. No locking rings or nuts which increase the chances of loose or broken parts.

  • Industry-leading safety features in sensor technology.
  • Safe coupler locking complies with updated European EN474 safety standard.
  • Keep everyone on the job site safer. The operator stays safe in the cab and no assistance is required to connect or disconnect hydraulic hoses during attachment changes.
  • Multiple electronic and mechanical measures in place to keep attachment secure, even if a pressure loss occurs.
  • Operator has visual and audible confirmations from inside the cab of successful attachment connection.
  • Heavy-duty locking wedge design keeps connections tight and in place during use.

  • Attachment switching with a hydraulic connect coupler:
    • Quick changes mean operators will utilize task and application appropriate attachments, increasing overall productivity and extending the life of the attachments.
    • The ability to exchange attachments easily can reduce the number of machines needed for a job.
    • Fast attachment changes with the hydraulic connecting interface will save time over static couplers or pin-on attachments.
  • Electric connector allows for full functionality when working in combination with tiltrotators, ditch cleaning tilt buckets, and mulchers or other attachments with electronic harnesses for grade sensors or tool functions.
  • Each coupler comes standard with a lifting hook with 5-, 8- or 10-ton lift capacity depending on the size class.
