Adjustments
It is not possible to have an exact spreading chart for equipment that makes use of the centrifugal force principle, the distributed quantity depends on the speed , on the radius of distribution, on the quality and humidity of the fertilizer or seed and rough- ness of the land. The fertilizer must always be stored and conserved adequately, so as to keep it’s physical characteristics unchanged. It is necessary to set the speed of the pull spreader, before starting the operation of distribution, trying, in the possible limits, to keep it constant for the total duration. The spreading chart contains the information, in order to determine the quanity to spread in a field; these must be completed by the experience and competant operator.
How To Adjust The Spreader Vanes
In order to assure an even distribution on both sides of the spreader, depending on the different specific weight of the material used, the vanes on the disc can be set to different positions.When all the vanes are put in hole 1 (Shown in picture), the distri- bution of the material is increased towards the left compared to the way the tractor is moving. But if you put the vanes in hole 4, the distribution will be more towards right. Moving vanes from position 1 to 4 on same speed there will be an increase in the distibuting width. This regulation must be made compared to the type of material you are spreading and from experience.
Spreading disc’s vanes regulation
Such a regulation must be done in accordance with the material type that is used and the operators experience.
