Features
Work Made Easy
The 903 makes work easy with a 17% increase in horsepower with the all-new Cat C1.7 engine. This provides for improved performance when operating on grades and when using drive, steer, and lift simultaneously. The all-new optional hydraulic skid steer loader style coupler allows for faster and more efficient work tool changes while providing a viewing window that enables the operator to see the fork tips when using compact wheel loader style forks. Optional front and rear diff-lock can be activated on the fly, providing maximum traction in slick underfoot conditions.

Configured for Success
Configure the 903 for success with new options such as engine and ground speed control, ideally suited for hydro-mechanical work such as using a broom. With the addition of a work tool electrical harness option, you can now run more tools than ever before. Two loader linkage options, standard and high lift, provide either improved capacity or improved lift height based on your application.
