Abstract
In a system including, for example, an irrigation line supported by towers and rotatable about a central pivot, a plurality of towers are driven by water motors and include brake systems. Each brake system provides that upon sufficient water pressure being supplied to drive the water motor of that tower, the brake is released, and conversely, as such water pressure falls below a certain level, the brake is applied. The line also includes control means for providing that, as one tower travels faster or slower than adjacent towers, water pressure supplied to the water motor of that tower is adjusted to compensate for such travel.
