Boosted Productivity The new engine is teamed up with the new hydraulic system to yield more production with less fuel consumption. The Eco Zone is a new fuel-efficient feature. -^^^B The new engine complies with the Emission The new engine, combined with the new hydraulic system, boosts power and operating efficiency. The Eco Zone helps slash fuel consumption while yielding high The Auto-Idle further cuts fuel consumption: When shifting the control lever to neutral, the engine slows automatically down to idling speed after four seconds later. This reduces emissions and sound as well. The proven...
