    Abstract: A universal mount for installing a canopy onto tractor and mower ROPS (roll bars). The ROPS may have left and right downward extensions and a bridging element between the left and right downward extensions. The universal mount includes a clamp to secure the universal mount onto a ROPS, a crossbar attached to the clamp extending parallel to the bridging element, and plates on each opposed end of the crossbar. Each plate has at least one slot adapted to receive a fastener. The universal mount can be clamped to a ROPS with the canopy fastened by aligning holes on the canopy with the slots and passing fasteners through. The canopy attitude can be adjusted to a desired orientation by positioning fasteners at a selected position in the slots.
