MP Rotator Series: How to Adjust Hunter's MP Rotator
Adjusting the arc and radius of an MP Rotator is an easy task. There are two adjustments, arc and radius, that can be made on an MP Rotator. Arc: The degrees of coverage of a sprinkler from one side of pattern to the other. A 90-degree arc would be a quarter-circle sprinkler. In other words, how far to the left and to the right the sprinkler will be adjusted to rotate. Radius: The distance of throw from the sprinkler head to the furthest point of water application.
