[0020] 4. The low-pressure multi-nozzle reel sprinkler operates through the coordinated operation of the roller, the wheel axle, the annular chute, the ball slider, the mounting shaft, the obstacle clearing rod and the cutter, so that the two obstacle clearing rods can cooperate to clear the obstacles in front of the second row frame, and the two cutters can cut the weeds to facilitate the passage of the second row frame, thereby avoiding the presence of a large number of obstacles and weeds on the route when used in the grass, blocking the route and affecting the sprinkler efficiency.
