The D61-23 offers two gearshift modes: Variable and the new Customizable Quick shift. Variable shift mode provides 20 incremental speed settings for the operator, while the new Customizable Quick shift provides 3 speed settings; all can be adjusted in the monitor to obtain the right speed for different operator preferences.

• Newly designed joystick controls for power and comfort

Komatsu’s ergonomically designed Palm Command Control System (PCCS) gives operators maximum control, offering a relaxed posture and superb fine control to minimize operator fatigue.  Thumb push buttons simplify transmission speed setting shifts shown graphically in the monitor. The travel lever turning sensitivity can now be easily adjusted in the monitor to better match operator preferences. The new blade electro-hydraulic controls incorporate a new blade angle switch and float switch.  The blade feel can also be adjusted in the monitor to best match operator preference.  

• New cab design improves operator environment

The new D61-23 crawler dozer’s comfortable working environment allows operators to concentrate on the work at hand for increased productivity. The interior cab decibel level has been decreased to 76 dB for a quiet work environment. A comfortable standard air ride seat with heat enhances operator comfort further. A standard rear view monitoring system can be synchronized with reverse operation.

A new HST version of the large 7” high-resolution LCD color monitor in the cab displays all machine information.  An easy to use tab system allows operators to select the parameters they want to see and also provides quick troubleshooting for a service technician with easy to use on-board diagnostics.

• Customer peace-of-mind is standard because of Komatsu CARE®

Komatsu remains focused on lowering the customer’s ownership costs by engineering machines with increased fuel efficiency and productivity.  Komatsu CARE® complimentary scheduled maintenance is standard on all D61-23 crawler dozers for the earlier of 3 years or 2000 hours.  Services are performed by factory certified technicians using only Komatsu genuine parts and fluids. Also included are complimentary KDPF exchanges at 4,500 hours and 9,000 hours in the first five years. 

• Convenient maintenance equals reliability

Recognizing that maintenance is critical for successful equipment uptime, Komatsu has designed the D61-23 with easy routine maintenance in mind.  Daily engine checks are grouped at the left hand side of the engine compartment. While the rear mounted swing-up reversible electronically-controlled hydraulic fan allows for easy checking of the radiator, oil cooler and charge air cooler.  A manually reversing fan allows for quick cleaning of the radiator.  The D61-23 also comes standard with the Parallel Link Undercarriage System (PLUS). This rotary bushing system doubles the undercarriage life compared to prior conventional systems, significantly lowering owning and operating costs.
