Abstract
A folding rollover protection system includes an upper ROPS hinged to a lower ROPS and movable between an upright position and a folded down position. An isolation member may be urged between the upper and lower ROPS to separate them from each other. The isolation member may be a resilient wedge-shaped member positioned between a first wedge and a second wedge. The first wedge is movable toward the second wedge to urge the isolation member against one of the ROPS, isolating the upper ROPS from the lower ROPS.
