Center Articulating Frame:
The tractor frame pivots in the center, allowing the rear tires to follow in the same path as the front tires. This allows the tractor to easily navigate around obstacles and without damage to the turf.
Center Oscillating Frame:
The front frame oscillates independently of the rear frame. This allows the Ventrac to adapt to the terrain and keeps all four drive tires in contact with the ground even on the roughest terrain.
