|Wow, see this tractor's tires, Cool! It is the Case IH's Steiger Quadtrac 4WD tractor($TBA) that features four independent tracks instead of tires. It offer increased traction and flotation over soil, more featuring at below.
Each 30" rubber track provides 68.5 inches of contact with the ground surface. Each track can pivot up and down 10 degrees, allowing the track assembly to follow the ground contour. Because each track assembly works independently, the track remains on the ground. And with the 26 degrees of oscillation between the front and rear of the tractor, operators enjoy a superior ride, while the tractor provides superior flotation and traction. Depending on the tractor's configuration, soil compaction will be as little as 4.9 to 5.3 pounds per inch.
"Case IH 4WD tractors feature three frame sizes and an industry-leading long wheelbase and drawbar design for superior conversion of horsepower into pulling power ĘC while delivering comfort, convenience and reliability."
