Abstract
A spreader has a hopper the lower region of which comprises a wall portion which coincides in part with a sphere and contains outlet ports for material to pass at an inclined angle from the hopper to a rotating distribution member. The free aperture of each port is adjustable by a dosing slide. These dosing slides are controlled by an adjusting mechanism capable of displacing either one of the dosing slides without displacing the other.
