Abstract
A combined drop and broadcast spreader for granular material is mountable on the implement of a front end loader. The spreader includes a hopper containing a plurality of discharge openings in the bottom. A rotatable impeller in the bottom forces the granular material from the openings during drop spreadings. A rotatable broadcast disc is coupled to the rear wall of the hopper for discharging granular material in an arc-like pattern. The hopper includes a hole with an auger supplying and metering granular material from the hopper to the broadcast disc. An auger-like agitator moves the granular material in the hopper to the hole.
