Key Features and Performance Highlights

1. Visibility and Blade Design
   • The machine’s visibility received high praise, attributed to its sloped hood, low-profile cab pillars, and large glass areas.
   • A six-way PAT blade with a manual pitch adjustment allows for versatile grading and cutting tasks.
2. Cab and Controls
   • An 8-inch touchscreen with minimal glare offers easy navigation and quick adjustments to hydraulic settings.
   • Blade shake and float features improve operational efficiency, particularly for fine grading.
3. Grading and Slot Dozing
   • The DD130 demonstrated smooth performance in fine grading, with easy dirt rolling and blade control.
   • Slot dozing showcased its power to handle full blade loads of tacky material effectively.
4. Slope Stability
   • With a low center of gravity and an oscillating serrated track system, the dozer maintained stability on steep slopes and wet surfaces.

Challenges Observed

1. Steering on Slopes
   • Steering power proved insufficient when maneuvering on slopes, especially with a blade full of material. Operators often had to reverse and reposition.
2. Hydraulics Sensitivity
   • Some operators found the hydraulic controls overly sensitive, even in medium-speed settings.
3. 2D Grading System Adjustments
   • The 2D system occasionally caused the blade to dip unexpectedly, complicating grade matching.

Operator Feedback

• Pros: Exceptional visibility, smooth grading performance, robust power in heavy conditions, and user-friendly touchscreen controls.
• Cons: Steering issues on slopes and sensitivity of the hydraulic system requiring fine-tuning for smoother operation.

Conclusion

The DD130 brings notable innovation to the dozer category with its focus on visibility, grading precision, and slope stability. While minor issues in steering and hydraulic sensitivity need addressing, operators commended its performance for fine grading and slot dozing. As Develon continues to refine its compact dozer offerings, the DD130 holds strong potential as a versatile machine for construction tasks.
