Abstract

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.
