The Cat B-Series 3 Compact Track Loaders and
MultiTerrain 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 increase
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.

Page 6
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 XT™ hoses for increased reliability and durability.
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.
