    Overview Summary

    When comparing the Komatsu GD955-7 and GD825A-2, the main differences lie in engine power, blade size, and convenience features. The GD955-7 offers a more powerful engine and a larger blade, along with built-in GPS and a standard AC cabin, while the GD825A-2 provides a more compact design with superior maneuverability.

    Komatsu GD955-7
    Pros:
    • More powerful engine with 426 HP
    • Longer blade length for broader coverage
    • Higher blade down pressure and pull
    • Larger fuel and hydraulic system capacities
    • AC cabin comes standard
    • GPS system comes standard
    • Greater maximum lift above ground
    Cons:
    • Larger minimum turning radius
    • Heavier machine with more ground pressure
    Komatsu GD825A-2
    Pros:
    • Smaller minimum turning radius for better maneuverability
    • Lighter machine which could mean less ground impact
    • Maximum reverse speed is very low, indicating potential granularity in speed control
    Cons:
    • Less powerful engine with 280 HP
    • Shorter blade length compared to GD955-7
    • AC cabin and GPS not standard
    • Smaller fuel and hydraulic system capacities
    Pros:
    Cons:
    Closing Recommendation

    If power and technology features are paramount for your large-scale grading tasks, the Komatsu GD955-7 would be the preferred choice. However, if maneuverability in tight spaces is essential and weight considerations are a priority, the Komatsu GD825A-2 might be the better option.
