What’s coming: 994H

• Four fully variable displacement pumps with integrated solenoids for optimized pump control

– Enables faster digging cycle times using full pump flow and reducing pump flow during inefficient operations, leading to an estimated 5% improvement in fuel efficiency (tons/gal)

– Lowers system heat load by reducing pump flow during inefficient operations and machine idle

• Positive Flow Control provides improved hydraulic response

– Reduced lever dead bands– Better bucket control

• Electro-Hydraulic features for improved machine operation

– Accurate kick-outs for raise, lower, and rack with greater capability for operator customization as in other K series LWLs

– Software controls to soften bucket impact into stops and cylinder travel to end of stroke

– Soft detent controls, easier operator use
