CONFIGURED FOR SUCCESS

Cat® wheel loaders set the standard for productivity, fuel efficiency and operator comfort. The Cat 906 Compact Wheel Loader has a high torque C2.8 engine that works in conjunction with an intelligent hystat power train to deliver exceptional fuel efficiency. Dependent on regional requirements our engines meet U.S. EPA Tier 4 Final and EU Stage V emission standards with a clean emission module designed to manage itself so you can concentrate on the task at hand or emit equivalent to U.S. EPA Tier 3 and EU Stage IIIA.

ENJOY ALL DAY COMFORT

All new cab is spacious, quiet and comfortable with all around 360° visibility to keep you productive throughout the day. Seat-mounted controls feature a multifunction joystick for lift and tilt functions with an integrated thumb operated speed range, forward/neutral/reverse (FNR) switch, trigger operated differential lock and constant flow. Optional fourth function joystick also available.
Digital display with soft touch buttons for customized settings to easily control linkage and drive train to further enhance operator comfort and safety.

EFFICIENTLY POWERFUL

Cat C2.8 engine provides a cleaner, quieter operation while delivering superior performance and durability through a high torque, low speed design. Caterpillar’s exclusive Intelligent Power Management system monitors operator input and available power to keep the machine working at peak efficiency.
“Shift on the go” locking differentials and hydrostatic transmission provide smooth and powerful operation while increasing the efficiency of machine cycles. New Powertrain (Utility) Mode via the display enables right pedal machine operation giving further improved operator controllability of attachment RPM versus machine ground speed over creep control and inching pedal.

WORK MADE EASY

All-in-one joystick to keep eyes on the work while maximizing operation of hydro-mechanical attachments with a state of the art pressure compensated electro-hydraulic system. Optimized Z-bar linkage for great performance and versatility with buckets that now have the DNA of the larger Cat loaders, such as curved side plates and a flat torque tube for parallel reference to the cutting edge.

CUSTOMIZE YOUR EXPERIENCE

Work as one with your machine by customizing the controls. Operator can adjust machine responsiveness with the push of a button based on the attachment or application. Once customized, settings can be locked with “simplified mode” to ensure the machine is consistent and intuitive for every user.
Machine security is enhanced with a standard keycode or optional Bluetooth® technology.

PURPOSE BUILT SPECIALTY MODELS

Machines can be built to meet industry and application specific needs: Agriculture, General Construction, Industrial and Waste, Landscaping or Snow Removal.
The 906 is availble with the following specific handler arrangements: Ag Handler and Waste Handler

AFTERMARKET AND SERVICES

Range of services and aftermarket retrofits and upgrades available to keep your machine going and configured for your application.
Service and maintenance parts available, including a range of self-service options (SSO) and dealer installed kits.
Integrated Technology available to reduce service costs and maintenance.

SUSTAINABILITY

The Cat® C2.8 engine meets U.S. EPA Tier 4 Final and EU Stage V emission standards.
Engine Idle Shutdown Timer reduces fuel burn, greenhouse gas emissions and unnecessary idle time by shutting down the machine after a pre-set idling period.
Remote Troubleshoot decreases maintenance time and keeps your machine running with maximum efficiency by allowing your Cat dealer to virtually test the machine while working. Once a problem is identified, a technician can fix it the first time, saving time and money.
Remote Flash minimizes downtime and maintenance time while keeping your asset running with maximum efficiency. Alerts for machine updates are sent virtually from your Cat dealer and updates can be deployed without a dealer technician needing to be onsite.
Advanced Electro Hydraulic System provides the optimum balance of power and efficiency while giving you the control you need for your precise jobsite requirements.
Engine Demand Fan is hydraulically driven to provide machine cooling only when needed, improving fuel efficiency and reducing greenhouse gas emissions.
Hydrostatic Transmission is an efficient way to transfer engine power to the wheels at low speeds versus a torque converter.
Efficient HVAC regulates temperature control. No need to leave the machine running to cool the cab.
Shift on the go transmission, means no need to stop so you keep your momentum.
