Although the Steiger Rowtrac series suspension looks similar to the Quadtrac series suspension, it is uniquely different...On each of the roller beam, a mount controls pitch roll and yaw along with some vertical load.....Two mounts in the center handle the primary vertical load. While the tractors is oscillating in the middle, each track moves independently.....The exclusive Case IH design now fits a wider under carriage.....The Rowtrac tractor is installed with a vertical suspension component that can be tuned specifically to meet the demands of the tractor and its environment, allowing you to get into fields earlier and maximize yield potential.
