A system for providing protection to a track type tractor includes a sweep arrangement having a pair of arms that are supported on a cab of the track type tractor. The pair of arms have first ends that are disposed rearwardly of the cab. The pair of arms also extend forward of an engine compartment of the track type tractor and have second ends that are coupled with a housing of the engine compartment. The system also includes a cross-brace having a pair of clamps and a bar. The clamps are releasably fastened onto the pair of arms of the sweep arrangement and located at an anterior region of the track type tractor. The bar has a pair of ends that are releasably fastened to proximal ends of the pair of clamps.

A vehicle (2), said vehicle including driving protection apparatus (14) which is located at or adjacent to the position of the driver (10) when operating the vehicle and wherein there is provided, in location with or adjacent to the said driver protection apparatus, visual display means which are selectively operated to provide an indication of the condition of the vehicle and/or driver of the vehicle and/or the environment in which the vehicle is located at a particular instant of time.

Vehicle rigidity apparatus for a vehicle are disclosed. A disclosed the vehicle rigidity apparatus for a central frame that extends in a lateral direction of the vehicle and lateral frames that extend in a front-rear direction of the vehicle and intersect the central frame. The vehicle rigidity apparatus also includes a reinforced bar that extends in the lateral direction of the vehicle supported by the lateral frames, the reinforced bar being movable from a position at the central frame toward a front of the vehicle in the front-rear direction and a movable portion at the central frame that moves the reinforced bar toward the front of the vehicle. The movable portion moves the reinforced bar toward the front of the vehicle to a position separated from the central frame.

Aspects hereof relate to a control system for a terrain working vehicle having an operator protection apparatus. In some aspects, the control system instructs and ceases an actuation of the operator protection apparatus to and between a raised position and a lowered position.

Aspects hereof relate to an operator protection apparatus having at least one over-center linkage. In some aspects, an operator protection apparatus can be raised and lowered by an operator from a seated position, for example, on a terrain working vehicle. Additionally, the at least one over-center linkage may automatically lock in the operator protection apparatus in a raised position. Accordingly, a mechanical force is then required to overcome the lock, and allow the operator protection apparatus to return to a lowered position.
