Articulating means the frame itself is built in 2 parts with a center hinge. In essence the rear wheels are mounted on the rear frame and the front wheels are on the front frame and the two frames are joined at the center point and move independantly.
Oscillating & articulating frames allow for not only side to side movement but also up and down movement. With a rigid frame like on a typical tractor if the front right wheel is lifted off the ground the rear right wheel also lifts. On a Steiner, Ventrac or Power Trac, if the front right wheel is lifted off he ground, the other 3 wheels are still firmly stuck on earth and providing full traction.
The combination allows these types of tractors to go over terrain that would normally scare a traditional tractor back into its barn, screaming like a little girl all the way.
The attached picture shows a side shot of my Ventrac with the finish mower deck. The hinge point is directly under the driver's seat. Even with those super low profile tires, this tractor will crawl down into a rock filled roadside ditch and climb back out the other side without skipping a beat or scraping its underside on the rocks.

BTW, I have a Kawasaki engine on my John Deere push mower and another on my JD weed wacker.
