A spreader for distributing a material on a surface. In certain
embodiments, the spreader may include a disk rotatable about an axis and
having an upper surface extending substantially radially from the axis. A
driver may operably connect to the disk to provide rotation about the
axis. A paddle may secure to the upper surface of the disk and rotate
therewith. The paddle may be aligned to rotationally engage particulate
material directed thereto and generate a centrifugal acceleration
therein. A controller may limit the centrifugal release of the
particulate material from the apparatus.
