Hydraulics
Exceptional lift, breakout and power to meet your needs.
High Performance Hydraulic System
Maximum power and reliability are built into the machine’s hydraulic system. In addition to providing
power to the tracks, this system also provides the loader lift and tilt functions, powers the auxiliary
circuit to drive work tools and drives the engine cooling fan. The hydraulic pumps are driven directly
off the engine for maximum hydraulic performance and reliability – no belts are used. The hydraulic
system also features:
• Standard auxiliary hydraulics to power work tools that are available through quick connect
hydraulic couplings rigidly mounted to the loader arm.
• Cat ToughGuard™ hoses for increased reliability and durability.
High Flow Hydraulics
High flow hydraulic system is available on the 257B Series 3 and 259B Series 3 for greater machine
versatility and increased work tool performance.
High Efficiency Cooling System
Cooling capacity is maximized through the use of a side-by-side cooling package and hydraulically
driven cooling fan.
• High-efficiency, hydraulic oil cooler lets the machine work longer and harder in higher ambient
temperatures, even with continuous work tool usage.
• Efficient, hydraulically driven cooling fan provides cooling even when the machine is under load.
• Optional variable speed demand fan provides improved fuel efficiency, increased machine
performance, reduced sound levels and improved cold weather performance.
