Abstract
Improved control over the distribution pattern and the amount of fertilizer, grass seed or the like dispensed by a broadcast spreader is accomplished by mounting a variable rate control device in a material directing chute secured below a basin wall of a hopper. A web or ramp portion of the chute is spaced below a discharge port in the hopper, and the rate control device is rotatably mounted in a housing formed in the rear of the chute to engage a shutter that is slidably mounted under the discharge port.
