Double – S Manufactured Products, a division of Northern Agri-Services, Inc., was founded in 1987 to cater specifically to the lawn care industry.  Our goal has always been to provide industrial quality replacement parts for various brands of sprinkler installation equipment.  Since our inception, we have created additional products to make your job easier and more efficient. 

In 1990, in association with the University of Nebraska Research, a stronger grade of steel was developed for the use in our Blades.  The Bullet design, which used a 2” standard bullet, was developed to prevent blades from “walking” out of the ground, especially in compacted or clay soil.  Pipe depth is more uniform, especially where lines must cross, because as blades are raised for the crossing, the pipe is not pulled out, but instead remains well below ground level.  No more stops to hand dig or repair crossings!  Using proven, custom designed adjustments of blade angles and special hardened, sharp blade edges, Double – S now provides very high quality replacement bullet blades for nearly any brand of sprinkler plowing equipment.
