Description:

The SD7N bulldozer is a crawler-type bulldozer, adopted overhead drive, hydrodynamic drive, semi-rigid suspension, and hydraulic control.

Its modular design simplifies maintenance and repairs.

The control system is logically and precisely engineered for optimal performance.

Equipped with a multi-functional display and a ROPS cabin, this bulldozer can be outfitted with attachments such as angle blades, U-blades, single-shank rippers, and triple-shank rippers.

It is an ideal choice for engineering environments like road construction, desert oil industries, power projects, and mining operations.
