A spreader for particulate material, the spreader being of the broadcast type having a hopper from which particulate material is discharged onto a rotating impeller. To provide adjustment for materials of various physical properties, a conically-shaped deflector is mounted between the hopper and impeller. The deflector is helically shaped at the bottom so that it has a gradually varying radius. By rotary adjustment of the deflector, particulate material can be discharged onto a preselected portion of the impeller.

In a spreader for particulate material having means for discharging said particulate material downwardly from said spreader and rotatable means in association with said discharge means for broadcasting said discharged material in a generally radial path, the improvement comprising a conically-shaped deflector axially mounted between said discharge means and said broadcast means with its wider dimension facing said broadcast means, the bottom edge of said deflector having a radius which gradually varies from a given value to a larger value, said deflector being rotatably adjustable about the axis thereof to one of said radii but remaining stationary during operation of the spreader, said deflector and discharge means being aligned so that particulate material is discharged onto the outer surface of said deflector, whereby upon discharge, particulate material is deflected onto a preselected portion of said broadcast means.
