Abstract
The fluid distribution discs include a plurality of fluid distribution channels that radiate from the fluid distribution disc origin to conically shaped tines connected at the perimeter of the fluid distribution disc. The fluid distribution channels are aligned with similar channels within a bushing securable to the fluid distribution disc radial portion. A stationary plate or disc valve has a disc valve fluid channel in a disc valve radial surface, which is in contact with the rotating bushing radial surface resulting in a periodic alignment between the disc valve fluid channel and each of the bushing channels. Fluid is pumped to a fluid port in a hub having a fluid port in fluid communication with the disc valve fluid channel. As the tines of the fluid distribution disc penetrate the field surface, fluid is channeled through the disc valve into the fluid distribution disc channels and the tines.
