BENEFITS & FEATURES
Operator Station
Superior comfort to keep you productive throughout the work day.


Operator Station

Sealed and Pressurized Cab
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.Operators spend long hours in the machine. The new sealed and pressurized cab keeps dust out and clean air in for greater operator comfort. Reduced sound levels within the cab also help reduce fatigue.

Seat Mounted Joystick Controls
Ergonomic, seat mounted joystick controls enable a wide range of comfortable operating positions for operators of any size. The seat and controls are independently adjustable to meet the specific needs of the operator.

Air Ride Seat Available
An air ride seat provides an unparalleled level of comfort in a compact track loader.

Advanced Machine Information and Control System
The optional Advanced Machine Information and Control System (AMICS) provides easy to read analog gauges for hydraulic oil and engine coolant temperature. The electronic display provides additional operating information such as engine speed, job clock anddiagnostic service codes. Selectable Work Speed Control and Selectable Implement Control allow the operator to dial in his machine to maximize production.

Additional Features for Maximum Comfort
  • Easy to read instrument panels
  • Optional air conditioner and heater for greater comfort in extreme conditions
  • Optional Selectable Pattern Control which allows the operator to select the control pattern they are most familiar with for greater productivity.

Steel Embedded Rubber Track Undercarriage
Industry-first suspended undercarriage for versatility, durability, and comfort


Low Ground Pressure
Caterpillar introduces the industry’s first fully suspended undercarriage for a Compact Track Loader. The heavy-duty torsion axles suspend the CTL undercarriage and can move independently relative to the machine and each other. These axles absorb most of the shock to the undercarriage, 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 tread design ensures a smooth ride and a great combination of traction and flotation. The 279C Series 2 delivers a ground pressure rating of 29.5 kPa (4.3 psi).

Durable Design
The CTL undercarriage system features highly durable and easily maintained components. Steel imbeds provide a rigid support for the entire width of the track and provide excellent durability in a wide variety of applications. Continuously wound cables hold these imbeds in place and provide tensile strength, ensuring the track does not stretch. Following the same philosophy as Cat Track-Type Tractors, the elevated external positive drive system keeps drive components away from ground debris. Planetary final drive motors improve torque and drawbar performance, delivering more power to the ground. Steel rollerswith metal face seals provide maximum protection for wheel bearings resulting in long-term durability and reliability in even the toughest conditions. The simple recoil grease tensioning system allows quick track tension adjustment.

Radial Lift Linkage
Built for tough working conditions.


Radial Lift Design
The 279C Series 2 features a radial lift design, delivering excellent digging performance with superior performance.

Power Train
Aggressive performance with fuel efficiency.


Engine
The high performance power train provides high engine horsepower and torque. The machine features the Cat C3.4 DIT engine--a rugged, reliable engine that meets worldwide 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.

Electronic Torque Management
The Electronic Torque Management system maximizes power to the ground and prevents the engine from stalling in tough digging and dozing applications for maximum productivity. The system allows part throttle operation which provides smoother machine operation and reduces fuel consumption.

Selectable Work Speed Control
The optional Selectable Work Speed Control lets you select the ground speed that is best suited for the application. This feature is useful in operations such as trenching and cold planing that require precise machine control at relatively slow and constant speeds.

Hydraulics
Exceptional lift, breakout and power to meet your needs.


Hydraulic System
Maximum power and reliability are built into the Cat Compact Track Loader hydraulic system. In addition to providing power to the tracks, this system also powers the loader lift and tilt functions, powers the auxiliary circuit to drive work tools and drives the engine cooling fan. The hydraulic system features increased lift and tilt breakout forces allowing you to move more material and get more done. The continuous demand fan provides improved fuel efficiency, increased horsepower, reduced sound levels and improved cold weather performance. Cat ToughGuard™ hoses increase reliability and durability. High capacity hydraulic tank and side-byside cooling package keep components cool for maximum durability.

High Flow XPS
High flow XPS hydraulic system is available on all models for greater machine versatility. Maximum performance can be maintained regardless of the worktool speed or conditions with this load sensing, pressure compensating system. Cat cooling systems are sized to allow the operator to continuously powerhigh flow work tools in conditions that cause competitive machines to overheat.

Selectable Implement Control
The Selectable Implement Control option with three levels of control gives the operator the ability to adjust the responsiveness and speed of the lift and tilt functions for more precise implement control.

Standard Two Speed
Two speed, offered as standard equipment, increases top speed up to 13.6 km/h (8.5 mph) allowing you to finish jobs faster.

Work Tools
Do more jobs with one machine using Cat Work Tools.

Work tools can be changed quickly and easily with the Cat Compact Track Loader’s quick coupler system. The standard quick coupler features manual engagement and disengagement of work tools using two high leverage handles. The optional hydraulic quick coupler allows the operator to quickly change tools without leaving the cab.

AccuGrade™ Grade Control System for Skid Steer, Multi Terrain and Compact Track Loaders
Common to AccuGrade systems for Track-Type Tractors and Motor Graders, this deeply integrated solution automates the machine’s electrohydraulic controls to achieve a consistent grade across the work site, improve accuracy and increase productivity, ultimately lowering operating and material costs.

Serviceability
Simplified service and maintenance save you time and money.


Easy Maintenance
