Key Differences Explained
1. Size and Power
One of the noticeable difference between the models are their size and power output. The D839EX/PX22 delivers almost double the horsepower of the D39EX/PX-22. Therefore, making it much better suited to all kinds of heavy-duty applications.
The D39EX/PX-22 is compact and seamless to operate, even in restricted areas.
2. Application Suitability
The D39EX/PX-22 even excels in projects that require high precision, such as grading, levelling, and small-scale excavation. The small size allows for better manoeuvrability and low operational costs.
The D85ESS-2A is primarily designed for bulk material handling, making it suitable for mining and large infrastructure projects where productivity is the top priority.
3. Productivity and Efficiency
While the D85ESS-2A certainly has high productivity due to its large blade capacity and engine power, it also consumes more fuel and incurs higher operational costs. In contrast, the D39EX/PX-22 provides better fuel efficiency and lower maintenance costs. Making it a cost-effective solution for small projects.
4. Operator Comfort and Technology
Each KIPL bulldozer model has been developed with operational features such as ergonomic operator controls and efficient hydraulic systems to enhance their use. The powertrain of the D39EX/PX bulldozer includes a hydrostatic transmission and an electronically geared system, providing ease of use and maintenance.
The D85ESS-2A is a large machine that offers enhanced durability and performance-focused engineering, suited for longer working hours in demanding conditions.
Which Bulldozer Should You Choose?
While choosing between these two models depends mainly on the scale and type of your project:
Choose D39EX/PX-22 if your project involves roadwork, urban construction, and smaller construction sites where both efficiency and manoeuvrability are critical.
Do choose D85ESS-2A if you are seriously working on large infrastructure, mining, and higher-volume projects.
