The CX17B delivers more power, greater stability and faster cycle times than the CX14 it replaces. Engine power is 15.15 net hp, a 30% increase. Swing speed is 0 to 8.6 rpm (+40%). Bucket force is 3,417 lbs. (+19%) with an arm force of 2,248 lbs. (+16%). Lift capacity over the side is 1,380 lbs., up 8% to 10%. A larger capacity hydraulic pump allows for faster cycle times, and a longer boom increases the working range by nearly half a foot. Retractable tracks allow the machine to pass through a 39-in. opening for use in tight working conditions. A 20% increase in overall machine weight and a wider stance provide greater stability, while retaining a zero tailswing.
