The Cat B-Series 3 Compact Track Loaders and
Multi Terrain Loaders feature suspended undercarriages for lower ground pressures and superior traction. Spacious, ergonomic operator station and easy-to-use pilot operated joystick controls keep you comfortable throughout the work day. High performance power train, advanced hydraulic system, traditional Cat reliability 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 one-touch 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 machine’s rear and sides. The side windows remove easily for cleaning.
Additional Features for Maximum Comfort
The B-Series 3 machines offer the following additional features to help you on the job:
•Suspension seat option for even greater operator comfort.
•Easy to read instrument panels.
•Optional air conditioner and heater for greater comfort in extreme conditions.
•Standard floor mat with footrest provides non-slip surface and can be removed for easy cleaning.
•Ergonomic, contoured and padded armbar provides comfortable operation.

Undercarriage
Choice of undercarriage to meet your specific needs.
Multi Terrain Loader Undercarriage
The Cat 247B Series 3 and 257B Series 3 Multi Terrain Loaders feature a fully suspended, rugged, durable rubber track that is lightweight and pliable, yet reinforced with high tensile strength cords. The undercarriage provides extremely low ground pressure, allowing these machines to operate over sensitive surfaces and in soft underfoot conditions. The independently suspended undercarriage distributes the load and greatly reduces shock and vibration throughout the machine for a comfortable ride and excellent bucket load retention. The undercarriage also features:
• Heavy duty torsion axles that independently suspend each side of the machine frame for a smoother ride over rough terrain, even at high speeds.
• Components that are replaceable as individual wear items, reducing owning and operating costs.
• Low ground pressure: 27.3 kPa (4.0 psi) for the
247B Series 3 and 31 kPa (4.5 psi) for the 257B Series 3.
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. Heavy-duty 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:
• Steel embedded rubber track that provides excellent durability in a wide variety of applications.
• Steel rollers with metal face seals for long-term durability and reliability in even the toughest conditions.
• Simple recoil grease tensioning system for quick track tension adjustment.
• Two track options – standard track width of 320 mm (12.6 in) or optional 400 mm (15.7 in) track.
• 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.

Power Train
Aggressive performance with fuel efficiency.
Cat Engine
The high performance power train provides high engine horsepower and torque. The B-Series 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.
Anti-Stall Feature
The anti-stall 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 and as an option on the 257B Series 3 Multi Terrain Loader to improve cycle times and get the job done faster.
Lift Linkages
Built for tough jobs.
Choice of Lift Designs
Two types of lifting arrangements are available – vertical lift (path #1 above) and radial lift (path #2) – to meet your specific application needs.
Vertical Lift
The 257B Series 3 and 259B Series 3 feature the vertical lift design which provides extended reach and lift height for quick and easy truck loading and material placement. The lift height is 3069 mm (121 in) on the 257B Series 3 and 3046 mm (120 in) on the 259B Series 3.
Radial Lift
The 247B Series 3, with its radial lift design, delivers excellent digging performance with superior mid-lift reach.
