MID-SIZE DOZER IS SMOOTH AND AGILE
Komatsu's D51EX-22 and D51PX-22 mid-sized crawler dozers are outfitted with Komatsu's fuel efficient 6.69 litre, Tier 3 emissions certified, SAA6D107E-1 engine. These new models push with 130 hp at 2,200 rpm and range in operating weight from 27,778 to 28,881 pounds, depending on version. Both standard (EX) and low ground pressure (PX) models are available.
The steering system provides smooth agile movement when dozing, even in gradual turns, permitting the D51 to approach dozing objects accurately in corner grading and sidewall operations - ultimately keeping more material on the blade and making it a more productive machine. The D51's large power angle tilt blade offers a capacity of 3.5 to 3.8 cubic yards. The blade control joystick utilizes the Proportional Pressure Control (PPC) valve for fine control of machine operation. Selection of either variable or Quick-shift Speed control allows the D51 dozers to achieve maximum efficiency during fine or rough grading operations with optimal travel speeds to match job conditions and operator preferences. Switching between modes is as simple as pushing a button.
When the Variable Speed Selection is selected, travel speed is adjustable through a 20 increment speed range. Travel speed is shown by an LED monitor display, and is controlled by utilizing the shift buttons on the PCCS travel control. The Quick-shift Speed Selection enables the operator to select three predetermined speed settings to match job conditions.
The new cab forward, integrated ROPS / FOPS dozer cab, designed with large glass windows, provides more room for the operator and improves front, side and rear visibility, while increasing comfort. Internal cab air pressure and air filters prevent dust from entering the cab, and new cab damper mounts suppress noise and vibration when traveling over rough terrain. The D51 also boasts extended undercarriage life with the auto adjusting front idler guide, larger link and large diameter bushing for reduced undercarriage maintenance costs.
