JCB moves to EasyControl™ servo system
on 3CX and 4CX Backhoes.

JCB has implemented its new EasyControl seat-mounted servo control system in its new 3CX and 4CX backhoe loaders. Since pioneering the seat-mounted pilot-control concept in backhoes several years ago, EasyControl is the very latest generation from the world's largest producer of backhoes.

According to Jim Blower, senior product manager at JCB North America, the new EasyControl gives the operator all the convenience and ease of pilot controls while at the same time giving him the FEEL and speed of the manual controlled machines.

"A flow-sharing valve block limits the amount of oil available to each cylinder. Switching these machines to full-flow valve blocks allows them to distribute the maximum amount of oil available to any cylinder, making single service cycle time faster and giving the operator total control over the backhoe speed."

The EasyControl system also improves operator/control feedback by changing the hydraulic circuit in the backhoe from a "closed-circuit" to an "open-circuit." With an open circuit, neutral circuit oil flows through the valve-block any time the engine is running and turning the pumps, making hydraulic power available on demand. Lever movement determines the amount of power available at the bucket tooth, allowing the operator to control how much force is applied to a given obstacle in the ground.
