JCB has made improvements to its 3CX and 4CX backhoe loaders.
The EASYCONTROL system changed the hydraulic circuit from “closed circuit” to “open circuit.” With an open circuit, neutral circuit oil flows through the valves at any time the engine is running and turning the pumps, making hydraulic power available on command. Lever movement determines the amount of power available at the bucket tooth, allowing the operator to control how much force is applied.
The 3CX and 4CX backhoe loaders feature a fuel tank made from a highly resistant composite material that makes the tank less susceptible to rust and heavy impact damage. A steel tank guard protects the underside of the tank and the machine’s steps are mounted to the backhoe’s frame instead of its fuel tank.
The 3CX and 4CX backhoes no longer use the Hydraulic Speed Control (HSC) switch. The new backhoe models automatically dump one of the hydraulic pumps directly to the tank when there is no need for the pump to be engaged. “This feature can result in a fuel savings of 15 to 20 percent when the backhoe loader is driven at higher speeds,” says Jim Blower, senior product manager at JCB.
