<p>Agricultural spreaders have a pair of spinners (8) which throw powders and granules to the sides of the spreader in a progressive band. A deflector assembly made of sheet metal has a horizontal cover (2) overlying the spinners (8) with a port (6) through which the spinners are supplied with material. For each spinner there is an upright fixed front deflector (56) at the edge of the spinner to prevent material being thrown against the spreader; an upright rear adjustable deflector (50) at the edge of the spinner to prevent material being thrown to the rear of the spreader; an extension (16) of the cover lying behind the spreader wheel (40) has a series of upright, side by side deflectors (26, 30) which project into the airstream leaving the spinner. The side by side deflectors cause minimum deflection but the material does not strike the spreader (40) and build-up of powder fines is minimized.</p> |
