Abstract
A centrifugal spreader (FIG. 1) for spreading granulated fertilizers has a funnel-shaped hopper, a discharge outlet in the lower portion of the hopper, and adjustor means for adjusting the size of and shutting off the outlet. A drivable agitator is disposed in the hopper, and spreading means 11 is disposed beneath the hopper for receiving fertilizer issuing from the outlet and spreading the fertilizer. The spreader 11 is releasably mounted on a drive shaft 16 and is exchangeable for a different spreading means. The spreader can be set in a position in which the distance (A) between the highest point of the spreader and the part of the hopper situated above said highest point as seen longitudinally of the drive shaft, is greater than the distance (B) between the lower edge of the fastening means 14 which releasably secures the spreader on the drive shaft, and the upper end of the drive shaft. Thereby removal of the spreader is facilitated.
