The Cat 259B Series 3 Compact Track Loader features a fully suspended, steel embedded rubber track undercarriage for versatility, durability and comfort. High performance power train, advanced hydraulic system and a wide range of Cat Work Tools improve your productivity in the toughest working conditions.

Operator Station



Superior comfort to keep you productive throughout the work day.

All Day Comfort



Comfort and ease of operation have been designed into every aspect of the operator station. The wide, spacious interior and uncluttered floor provide a comfortable work environment with excellent head, shoulder and leg room to keep productivity high and fatigue low. The adjustable seat and low effort controls keep the operator comfortable throughout the work day.

Low Effort Joystick Controls



Ergonomic, pilot hydraulic controls deliver precise control with minimal effort. The right joystick controls the loader raise, lower and tilt functions while the left joystick controls the forward and reverse travel speed plus direction. Optional deluxe joysticks provide additional auxiliary controls with fingertip control of many work tool functions, including proportional work tool hydraulics and work tool electrical. Basic and deluxe joystick functions include onetouch continuous auxiliary hydraulic flow and momentary auxiliary hydraulic flow.

Excellent Visibility



The wide cab opening offers an exceptional view to the work tool. The sloped angle of the engine compartment allows excellent visibility to the rear of the machine. The standard rear view mirror gives the operator a panoramic view of the machines rear and sides. The side windows remove easily for cleaning.

Additional Features for Maximum Comfort



The BSeries 3 machines offer the following additional features to help you on the job ulli Suspension seat option for even greater operator comfort.lili Easy to read instrument panels.lili Optional air conditioner and heater for greater comfort in extreme conditions.lili Standard floor mat with footrest provides nonslip surface and can be removed for easy cleaning.lili Ergonomic, contoured and padded armbar provides comfortable operation.liul

Undercarriage



Fully suspended, steel embedded rubber track undercarriage.

Compact Track Loader Undercarriage



The Cat 259B Series 3 Compact Track Loader features a fully suspended, steel embedded rubber track undercarriage for versatility, durability and comfort. Heavyduty torsion axles suspend the undercarriage and can move independently relative to the machine and each other. These axles absorb most of the shock to the machine and operator, especially over rough terrain. This means smooth travel, even at high speeds, as well as better load retention and greater productivity. The undercarriage also features ulli Steel embedded rubber track that provides excellent durability in a wide variety of applications.lili Steel rollers with metal face seals for longterm durability and reliability in even the toughest conditions.lili Simple recoil grease tensioning system for quick track tension adjustment.lili Two track options standard track width of 320 mm 12.6 in or optional 400 mm 15.7 in track.lili Low ground pressure 41.2 kPa 6.0 psi with the standard track and 34.4 kPa 5.0 psi with optional 400 mm 15.7 in track.liul

Power Train



Aggressive performance with fuel efficiency.

Cat Engine



The high performance power train provides high engine horsepower and torque. The BSeries 3 machines feature rugged, reliable Cat engines that meet U.S. EPA Tier 4 Interim and EU Stage IIIA emissions requirements.

Hand and Foot Throttles



Hand and foot throttles allow the operator to match engine speed to the task. The hand throttle is ideal for jobs requiring constant engine speed such as cold planing, trenching or snow blowing. The foot throttle lets the operator vary engine speed and minimize fuel consumption for other tasks such as load and carry, truck loading, grading and dozing.

AntiStall Feature



The antistall system maximizes machine power at all times by matching the engine torque with the operational requirements of the hystat and implement systems. This load sensing feature prevents the engine from stalling even during part throttle operation, keeping productivity high and fuel consumption low.

Two Speed



Two speed is available as standard equipment on the 259B Series 3 Compact Track Loader to decrease cycle times and get the job done faster.

Vertical Lift Linkage



Built for tough jobs.

Vertical Lift



The 259B Series 3 features the vertical lift design which provides extended reach and lift height for quick and easy truck loading and material placement. The lift height 3046 mm 120 in on the 259B Series 3.

Hydraulics



Exceptional lift, breakout and power to meet your needs.

High Performance Hydraulic System



Maximum power and reliability are built into the machines 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 reliabilityno belts are used. The hydraulic system also features ulli Standard auxiliary hydraulics to power work tools that are available through quick connect hydraulic couplings rigidly mounted to the loader arm.lili Cat ToughGuard XT hoses for increased reliability and durability.liul

High Efficiency Cooling System



Cooling capacity is maximized through the use of a sidebyside cooling package and hydraulically driven cooling fan. ulli Highefficiency, hydraulic oil cooler lets the machine work longer and harder in higher ambient temperatures, even with continuous work tool usage.lili Efficient, hydraulically driven cooling fan provides cooling even when the machine is under load.lili Optional variable speed demand fan provides improved fuel efficiency, increased machine performance, reduced sound levels and improved cold weather performance.liul

Work Tools



Do more jobs with one machine with Cat Work Tools.
