ABSTRACT:
Spreading apparatus for attachment to a vehicle for distributing granular materials such as fertilizer and the like, using air as the distributing medium. The spreading apparatus includes a rear-mounted boom and an air system in which the material distribution passageways are substantially straight from the discharge of the fans to the point of material introduction to the discharge nozzles along the boom. This is achieved by the use of two blowers that move air in opposite directions through a cross-over tube array into which the already-divided material is introduced into individual air passageways leading to the discharge nozzles mounted along the boom. The boom itself is designed so that it can be quickly and easily folded and pivoted for storage or transport.
