Unit E9: CaseIH 8230 Tracked Combine

Plot Comments

  • This combine with tracks was tested on the second installation only.
  • The plot titled E9_2 was measured down the center of the track face, between the sets of rollers. 
  • The plot titled E9_offset_2 was the same track aligned with the outside set of rollers over the center. There stress in at the 6 inch depth is increased under these rollers showing that the pressure distribution is not uniform across the face of the track.
  • Also notice that the 12 inch and 20 inch depths are for all purposes the same amount of load. The stress at these depths is more associated with the weight of the vehicle and not the amount of floatation that the track or tire may have.
