One of said members has an extension which projects substantially across the axial end of the lever so as to protect said end of the lever.

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.
