An operator's cab is mounted on the frame of a track-type tractor by mounting means comprising first and second pairs of upstanding posts. A first vibration damping means connects a lower end of each of the first pair of posts to the frame for isolating the posts against vibrations and for permitting the posts to pivot rearwardly upon release of a second vibration damping means, releasably connecting a lower end of each of the second pair of posts to the frame.
