The 904B features a skid-steer loader quick-coupler, high-flow hydraulics and powerful Z-bar linkage. The compact unit has a height of only 7 feet 10 inches (2.4 metres) and uses a bucket less than 6 feet (1.8 metres) wide.
The new loader replaces the Cat 902 and offers 52 net horsepower (39 kW) – equivalent to some 15% more power than the previous model. Operating weight is 9810 pounds (4450 kg) while standard bucket capacity is 0.78 cubic yards (0.60 cubic metres). The 904B can use a mechanical or hydraulic quick-coupler to handle a wide range of Caterpillar skid-steer loader work tools as well as compact wheel loader work tools.
Auxiliary hydraulic flow of 22 gpm (83 lpm) enables the loader to operate productively with hydro-mechanical work tools such as tillers, trenchers, snow-blowers and cold planers. The auxiliary hydraulic circuit is fitted as standard and is positioned so as to help avoid damage.
The Z-bar linkage gives the 904B excellent digging capability while breakout force is 8010 lb (35.6 Kn), according to the manufacturer. The linkage, bodywork and cab design afford the operator a full view of the work area, with the short back-end providing a clear view to the rear of the machine. Large, floor-length windows and a compact dash provide a clear line of sight to the work tool. The joystick implement control uses low-effort pilot hydraulics while the moulded-in forward/neutral/reverse switch is intuitive to use. The auxiliary circuit uses a proportional electro-hydraulic system for precise control.
