Abstract: An operator's cab for a work machine includes a ceiling structure and a floor structure. An operator's station is disposed between the ceiling structure and the floor structure, and is configured to position an operator in a driving position. First and second vertical support bars extend from the ceiling structure to the floor structure. The first and second vertical support bars are disposed forwardly of the operator's station and are spaced a substantially equal distance from a longitudinal axis of the work machine. Third and fourth vertical support bars also extend from the ceiling structure to the floor structure. The third and fourth vertical support bars are spaced a substantially equal distance from the longitudinal axis. The distance from the first and second vertical support bars to the longitudinal axis is less than the distance from the third and fourth vertical support bars to the longitudinal axis.
