    Particulars Komatsu GD755-5R Komatsu GD955-7
    Overview Summary

    The Komatsu GD755-5R excels in precision and power, suitable for demanding infrastructure tasks, with a 290 HP engine and agility favouring tight turning. The Komatsu GD955-7, on the other hand, targets large-scale grading tasks with a more robust 426 HP engine and longer blade, emphasizing durability and efficiency.

    Komatsu GD755-5R
    Pros:
    • Blade provides superior control and power, suitable for precision tasks
    • Advanced transmission type ensures efficient power delivery
    • Good forward speed of 45.0 km/hr
    • Features like sealed oil disc brakes and hydraulic steering enhance performance and safety
    Cons:
    • Smaller blade length compared to GD955-7 model
    • Lower engine power at 290 HP
    • Less advanced Tier compared to GD955-7
    • Lower maximum system pressure which may affect hydraulic performance
    Komatsu GD955-7
    Pros:
    • Higher engine power at 426 HP better suited for large-scale tasks
    • Cutting-edge technology for enhanced durability and efficiency
    • Longer blade length to cover more area per pass
    • Higher blade pull and down pressure for more effective grading
    Cons:
    • Slightly lower maximum forward speed compared to GD755-5R
    • Potentially less maneuverable due to larger size and turning radius
    • Higher fuel consumption due to larger tank could increase operational costs
    Pros:
    Cons:
    Closing Recommendation

    Choose the GD755-5R for tasks that require greater precision and maneuverability in tighter spaces. Opt for the GD955-7 for more extensive grading work where raw power, a larger blade, and advanced technology are essential. The right choice depends on the scale and specific requirements of your projects.
