Features

Work Made Easy

The 903D Makes Work Easy with a 25% increase in tipping capacity to handle classic landscaping materials along with a 25% faster ground speed. The optional hydraulic Skid Steer Loader style coupler allows for changing work tools without getting out of the cab. 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 new multi-function joystick, increased leg room, improved pedal positioning, easier entry/exit and optional speed sensitive ride control. The minimal engine overhang provides excellent rear and corner visibility, making the 903D easy to operate in confined areas.

Configured for Success

Configure the 903D 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 Worktool 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 precleaner and radiator screen for high debris applications. New rear tie down locations under the machine allow for easier transport, while a new engine oil fill location allows for easier access during engine oil changes.
