Newly implemented on the JCB 3CX and 4CX backhoe loaders, the Easycontrol seat-mounted servo-control system improves backhoe speed by changing the valve block from flow-sharing to full-flow, distributing the maximum oil available to any cylinder. The system also increases operator/joystick feedback, says JCB, by changing the hydraulic circuit in the backhoe from a closed to an open format, allowing lever movements to determine the amount of power available at the bucket tooth. Other upgrades to the JCB 3CX and 4CX backhoe loaders include a stronger fuel tank and the removal of the hydraulic speed control switch from the cab.
