The SFP Cruiser was created due to demand in the Anhydrous application world.
Farmers reported leaching of product they had applied in the field due to the injection slot remaining open after application.  They contacted Copperhead Ag for a solution to this problem, and we, over the next few years, developed the SFP Cruiser.  It is a very aggressive wheel that will absolutely crumble and close any type of ground in which you may be applying fertilizer.
The SFP Cruiser fits the Separate Fertilizer Placement row unit built by John Deere, mounted on any of their drills or air seeders.
