With revised powertrain, Cat’s 903D loader is faster, stronger, more comfortable

Caterpillar 903D Compact Wheel Loader

Caterpillar has introduced a revamped version of its 903 compact wheel loader that the company says is more powerful, more versatile and more comfortable to operate than the 903C2 that precedes it.

The new 903D boasts a new powertrain composed of a 40-horsepower, Tier 4 Final Cat C2.4 engine, and a hydrostatic transmission. The new pairing has increased travel speed by 25 percent to 12.4 mph.

The loader is also equipped with Cat-designed planetary-reduction axles that are available with optional differential locks. The diff locks can be engaged on the fly, Cat says, allowing the 903D to “respond instantly to changing ground conditions.”

Power and tools

Boasting a lifting power increase of 25 percent over the 903C2, the 903D is available with standard- (10 feet, 1 inch) or high-lift (10 feet, 7 inches) boom arms, with buckets ranging in capacity from 0.8 to 1.3 cubic yards.

Forks and a selection of powered and non-powered work tools are also available.

Those tools are powered by the 903D’s standard auxiliary hydraulic system, which delivers flow of up to 14 gpm, Cat says, at pressures up to 3,841 psi. Aux hydraulic lines with quick connectors and continuous flow come standard.

The machine is also equipped with a standard universal coupler. An electrically activated coupler is an available option, allowing operators to switch attachments from the cab.

The 903D features Z-bar loader linkage which Cat says provides “both aggressive bucket-digging ability and efficient control in fork applications.” Boom-float and return-to-dig functions are standard features.

New cab

Inside the cab, operators will find a new multi-function joystick which provides controls for directional changes, third-function hydraulics, the diff locks and continuous hydraulic flow.

The new cab also has more leg room, improved pedal positioning, and improved entry/exit over the 903C2, Cat says, along with a suspension seat and tilt steering wheel.

Optional features

Cat has added to the 903’s list of available options. It includes:

  • Creep control – Independent speed control
  • Throttle lock – Independent engine speed control
  • Work tool electrical harness – Allows use of attachments that have electrically operated functions
  • Ride control – Provides a smoother ride and reduces the amount of material loss out of the bucket when traveling
