Tractor Trial is a very challenging tractor driving off-road game. In the game, you need to drive a tractor across steep hills one after another. The tractor's large-diameter wheels can help it deal with uneven mountainous terrain, but it is more difficult for steep slopes. Pay attention to maintaining speed and maintaining balance. This is not an easy task. You have to try repeatedly and never give up until you find the most suitable speed to cross this hillside. Good luck!
