ABSTRACT:
A spreader for widely broadcasting agri-chemicals from a conventional airplane. Preferably the spreader comprises a central body comprised of an upper and lower top which diverge away from each other between a central front and a rear. The generally wing-shaped spreader includes a front throat having a mouth in which a plurality of spaced apart vane fronts are disposed. The vanes extend in arcuate spaced-apart relationship throughout the interior of the spreader, terminating in pivoted swallow-tail portions. Each swallow-tail portion includes a pair of pivoted tabs which can be adapted to deflect agri-chemicals in a desired fashion. Preferably the throat includes a releasable plate for quick connecting the spreader to the aeroplane, and a front, lower baffle plate may be adjusted to redirect air flow. Upon the opposite lateral outwardly diverging sides of the body two pairs of cooperating air injection chutes are employed. These chutes inject air within the lateral periphery of the spreader so as to insure uniform product output and prevent the creation of aero-dynamic "dead zones" within the apparatus.
