These constructions had been to start with essential by legislation in Sweden in 1959. Just before they have been required, some farmers died when their tractors rolled in addition to them. Row-crop tractors, before ROPS, ended up significantly perilous on account of their 'tricycle' structure Along with the two entrance wheels spaced near with each other and angled inward toward the ground.

They were being used in pairs, placed on possibly facet of a industry to haul a plow backwards and forwards involving them utilizing a wire cable.
