Overview
Configured for Success
The Cat® 903 is compact, yet powerful, delivering high performance with outstanding versatility. The all new C1.7 engine provides better all-around performance. Features such as engine and ground speed control, provides customizable control when running hydromechanical work tools. With an ergonomic cab, multi-function joystick, and optional ride control, the 903 allows the operator to enjoy all day comfort.
Features at a Glance
- 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.
- Enjoy All Day Comfort
-
Operators will enjoy all day comfort with a multi-function joystick, spacious leg room, ergonomic pedal positioning, easy entry/exit, and optional speed sensitive ride control. The all-new seat provides optimal comfort, while featuring yellow adjustment touch points that make finding that perfect seat position easy. The minimal engine overhang provides excellent rear and corner visibility, making the 903 easy to operate in confined areas.
- 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.
- Simply Reliable
-
Fully opening rear hood allows easy access to the engine compartment featuring side-by-side coolers and transparent fuel/water separator with optional engine air pre-cleaner and radiator screen for high debris applications. Rear tie down locations under the machine allow for easy transport, while the service locations under the hood provide easy access for daily maintenance.
