Abstract
In an earth scraper tractor a rigid side-tilt roll-over protection cab having the operator's seat secured to the cab rather than to the tractor frame is mounted on the tractor frame in a manner such that, in the event of roll-over, the mounting means plastically deforms without deformation of the cab, thereby absorbing impact energy, maintaining the integrity of the cab and preventing the cab from being torn loose from the cab. The mounting means includes a pair of transverse frame members secured to the tractor frame so as to extend outboard thereof and supporting the cab from below by pin connections which serve as part of the tilting mechanism. Also forming part of the mounting means is a deformable post member rigidly connected to the cab and pin-connected at its lower end to the tractor frame.
