Abstract
In the past, pipe pulling was limited to one blade, 12 inches to 18 inches long for pulling pipe for conventional irrigation systems. The Grid Master allows you to have several knives for pulling in grids of pipe for the new subsurface irrigation systems. The guide wheel assembly is what allows for speed of creating grids. Requiring no measuring or marking for the next line to be pulled in.
Claims1
The Grid Master will save 40 to 80% of the labor cost of installating sub surface/underground irrigation systems using netafim piping or it's equivalent, which is designed to be installed at 1″, 18″ or 24″ spacing in all types of planting areas. This could be days or weeks depending on the project size.
