ADjUSTMENTS

It is not possible to have an exact spreading chart for equipment that make use of the centrifugal
principle, as the distributed quantity depends on the speed, on the radius of distribution, on the
quality and humidity of the fertilizer and on the roughness of the land.
The fertilizer must always be stored and conserved adequately, so as to keep its physical characteristics
unchanged.
It is necessary to set the speed of the pull type spreader, before starting the operation of distribution,
trying, in the possible limits, to keep it constant for all its duration.
The spreading charts contain the indicative information, in order to determine the quantity to spread
in the field; these must be completed by the experience and competence of the operator.
4.2.1. h
ow to adjust the spreader vaNes
In order to assure a homogenous distribution on both sides of the centrifugal pull type spreader,
depending on the different specific weight of the used fertilizer, the distributor vanes on the disc can
have different positions.
When all the vanes are put in hole 1 (as shown in the picture), the distribution of the product is
increased towards left, compared to the way of the tractor moving. On the contrary, if the vanes are
put in hole 4, the distribution will be more towards right.
Moreover, moving the vanes from position 1 to position 4, at the same speed, there will be an increase
of the distributing width of fertilizer distribution. This regulation must be made compared to the type
of used fertilizer and to the experience of the operator.
Spreading disc's vanes regulation
Such a regulation must be done in accordance with the fertilizer type that is used and the operator's
experience.
