4.1 GENERAL DESCRIPTION
The fertilizer spreader with centrifugal distribution is a machine
for agriculture that spreads in the fi eld solid mineral fertilizer in
granular and powder form. It is pulled by and coupled to the tractor
by three points.
The fertilizer spreader consists of:
● A bearing chassis
● One hopper designed to contain the product to be spread
● Distribution components, driving and adjustment components
In the front side, the machine is equipped with a coupling
structure with three coupling points to the tractor.
The hopper in metal sheet has a truncated conical shape.
The fertilizer contained in the hopper goes through the dispenser
and, due to gravity, falls on the distributor - spreader system.
The dispenser is equipped with hydraulic controls to
open and close.
The amplitude of the dispenser opening is manually, adjusted
with a lever whose position is fi xed on a knob.
The distributor - spreader system consists of two horizontal
discs with rotational motion; on their upper surface is a series
of straight radial fi ns designed to distribute the product by means
of centrifugal force.
