ABSTRACT:
A foldable rollover protection system, or ROPS, is equipped with a lever to assist in raising and lowering the ROPS, without the necessity of the operator leaving the vehicle seat. The lever is slidably mounted in a guide on the upper, folding, part of the ROPS to allow it to slide out of the way when not in use. Appropriate holes are provided in the pivot bracket into which a pin can be inserted to lock the ROPS in its raised or lowered positions. A spring clip is provided which can hold the pin in place in either set of holes.
