ABSTRACT:
A supporting structure pivotally connects a first end portion of an operator's station to a first end portion of a supporting frame. A dampening device is connected to a second end portion of the operator's station and controls elevational movement of the second end portion of the operator's station in response to pivotal movement of the first end portion. A stop is connected between the second end portion of the operator's station and the supporting frame. The stop maintains the second end portion from excessive elevational movement during the application of excessive forces to the operator's station and prevents damage to the dampening device caused by excessive elevational movement.
