Tracked Bulldozer MD23

Descriptions of Tracked Bulldozer MD23:
Bulldozers MD23 are large and powerful tracked engineering vehicles. The tracks give them excellent ground hold and mobility through very rough terrain. Wide tracks of the heavy duty vehicle help distribute the bulldozer's weight over large area, thus preventing it from sinking in sandy or muddy ground.

Features of Tracked Bulldozer MD23:
1. CUMMINS NT855-C280 turbocharging diesel motor;
2. Longer ground contact length of the track ensured a stable performance of the bulldozer;
3. Hexahedron air-conditioner driving cab;
4. Imported VDO monitoring system: direct monitoring; high reliability;
5. Automatic angle and height adjusting of driver’s seat;
6. Independent anti-tumbling device is equipped in the engineering machinery;
7. Straight blade bulldozer; U blade bulldozer ; bulldozer with single teeth or triple-tooth ripper (ridge buster) are all available;
