Extend the frequency of digging up and levelling sprinklers with the Toro® INFINITY Razor kits. Over time the application of topdressing and settling can result in the sprinkler being in a depression below grade level. This can interfere with the natural roll of the ball, create trip hazards and take away from the natural beauty of the course. The Razor kits are designed to raise the top of the sprinkler in approximately 13 mm increments up to 38 mm (3 stages) without digging!
