An articulated dozer with a four point independent suspension system between a chassis and two support frames is described. The chassis includes a front chassis portion and a rear chassis portion connected by an articulation joint. The vehicle is compactly arrange so that the chassis and the two support frames fit between the track systems supporting and propelling the vehicle. Additionally, the engine is arranged near the articulation joint and lower than the top of the track systems for improved view and visibility. The cab is arranged over the track systems at the front of the vehicle for an optimal view of the blade.
