This app reinforces some principles of safe tractor operation and the importance of the use of a ROPS. The goal is to try to avoid obstacles, which may cause a rollover. Obstacles may be driven over at slow speed when the terrain is level, but not when the tractor is travelling on the sloped sides of the road. None of the obstacles may be driven over at high speed, except just after hitting a lightning bolt. The game starts over after a rollover unless you have obtained a ROPS. You get a second chance if you roll over with the ROPS, but the ROPS is lost until obtained again by hitting another ROPS coin.
