2.4 Hydraulic control connection
Each shutter control mechanism is separately operated by two individual hydraulic
cylinders. After disconnecting the fertilizer spreader from the tractor, the dust caps
should be refitted in the hydraulic connections and, to avoid dirt contamination, the
hydraulic hoses must be placed in the holders provided on the spreader.
Important: Before every operation, check to ensure that both open/close shutter sli-
des fully open and fully close.
2.4.1 Single acting two cylinder hydraulic shutter control
Oil pressure closes - Spring pressure opens
Tractors must be equipped with two hydraulic valves .
With optional extra double acting equipped units only one one control valve is
needed.
Prior to long transport journeys, or when filling, the hydraulic hose shut-off valves
must be closed , thus preventing subsequent opening of the shutter slides, should oil
inadvertently escape through the control valves.
By closing either the left- or the right-hand open/close shutter slide, the unit can be
operated to spread to one side only, thus avoiding double spreading or overspreading
in narrow field areas or on field edges and neighbouring fields.
If the
empty spreader is uncoupled from the tractor, the open/close shutter slides
must be left open so that spring tension is not weakened.
2.4.2 Double acting two cylinder hydraulic shutter control
Oil pressure closes and opens
Tractors must be equipped with two hydraulic valves . By closing either the left- or
right-hand open/close shutter slides, the unit can be operated to spread to one side
only, thus avoiding double spreading or overspreading in narrow field areas or on
field edges and neighbouring fields.
