The Caterpillar 903C is a compact wheel loader designed for construction, industrial, agricultural, landscaping, and snow-removal applications. Powered by a Tier 4-Interim Cat C2.4 turbocharged engine delivering 42 gross horsepower and 40 net horsepower, the machine achieves a maximum travel speed of 10 mph via hydrostatic transmission. With an operating weight of 9,150 pounds and a wheelbase of 5.9 feet, the 903C measures 15.9 feet in length and 8.2 feet in height, making it highly maneuverable in confined spaces. The loader features Z-bar linkage with a 0.8 cubic yard bucket capacity and impressive 5,171-pound breakout force. Its hydraulic system delivers 14 gallons per minute of continuous auxiliary flow, enabling compatibility with a range of standard-flow hydro-mechanical attachments including buckets, forks, snow blowers, and augers. The cab offers dual entry doors with sliding windows, tilting steering column, and low-effort hydraulic controls, with optional air conditioning and heat available. Notable features include oscillating axles with planetary reduction, differential locks for superior traction in challenging conditions, and optional external counterweights to increase lift capacity. The machine offers three tire options—12-inch construction type, 15.5-inch flotation type, and puncture-proof Flexport—allowing customization for specific job site requirements. With a full-turn static tipping load of 3,900 pounds and maximum reach of 2.9 feet at full lift and dump, the 903C delivers reliable performance in demanding applications while maintaining operator comfort and safety through ISO 3449 FOPS and ISO 3471 ROPS certification.
