Engine Provides power, reliability and acts as a working counterweight in the rear of the machine, for optimum machine balance. Cat C6.6 ACERT™. The Cat® C6.6 is a 6.6 liter (403 in3) displacement, sixcylinder, in-line configured engine that utilizes the Caterpillar® Common Rail fuel system for fuel delivery. It uses ACERT™ Technology, a series of Caterpillar engineered innovations that provide advanced electronic control, precision fuel delivery and refined air management, resulting in outstanding performance and lower emissions. 4 The C6.6 with ACERT Technology offers a compact design...

Fuel System. Through multiple injection fuel delivery, fuel is introduced in the combustion chamber in a number of precisely controlled microburst. Injecting fuel in this way allows for precise shaping of the combustion cycle. The ADEM™ A4 module directs the injectors to deliver precise quantities of fuel at exactly the right times during combustion cycle. This process provides precise control over a range of combustion variables, which can be regulated to produce higher performance with fewer emissions. Fuel is delivered at high pressure to each combustion chamber through a Caterpillar...

Operator Station Designed for operator comfort, convenience, and ease of operation throughout the workday. 6

Heating and Air Conditioning. Air conditioning is standard on 953D. Both the air conditioning and the heater deliver filtered, pressurized, temperaturecontrolled air to the operator and windows through 10 louvered vents. Messenger. Messenger is a new electronic monitoring system with real-time, visual feedback on engine and machine operating conditions. It provides information on diagnostic data, maintenance, and allows operating settings such as implement reactions. Electro-hydraulic implements controls. The new electro hydraulic implement controls on the 953D provide the operator with...

Hydrostatic Drive The electronically controlled hydrostatic drive helps provide quick response for shorter cycle times and increased productivity. The electronically controlled hydrostatic drive system automatically matches machine travel speed to the combined travel and implement loads on the machine, enabling maximum travel speed, up to the speed selected by the operator. Speed Switches. Both systems include speed mode switches. For the V-lever system a “work mode” and “travel mode” switch allows to best match the machine speed to various job conditions. Switching between travel and work...

Implement System Work smart and move more. Electro-hydraulic Implement Controls. Electro hydraulic implement controls on the 953D provide the operator with responsive, smooth and precise control of bucket and lift arms. They also allow the operator to set personal parameters through the optional Messenger such as implement reactions. Automatic kick-outs. The standard programmable automatic kick-outs provide flexibility and productivity for precise load and dump target heights. Tilt and lift kickouts are set by positioning the bucket or work tool and setting a rocker switch in the cab. Load...

Structure Durable slab section frame and loader tower with increased space for larger components. Z-Bar linkage. Breakout force is exceptionally high due to mechanical advantage of Z-bar linkage design, and hydraulic pressure applied to the head end of the tilt cylinder. Using a single tilt cylinder and linkage provides the operator a better view of the work area, bucket, and cutting edge. Mainframe and Loader Tower. The 953D Main Frame and Loader Tower is a single, slab rails with reinforced crossings, with castings and forgings incorporated at points of high stress, to distribute those...
