With a massive 222.6kNm of bucket tearout, fast cycle times are assured in all applications. The intuitive multifunction operation makes simultaneous tracking and excavating smooth and fast.
A JCB JS305 provides a solid, stable work platform for fast cycle times.

The control valve optimises hydraulic oil supply to different functions during combined operation.
