1.2 DESCRIPTION
The equipment described in this manual is provided with an independent hydraulic system and is
equipped with either a hydraulic pump ("mono-pump" to feed the whole circuit) or with two hydraulic
pumps ("bi-pump"; the former operates the set of disks and the latter all the other operations).
The equipment consists of four units:
a.) Framework
- a solid metallic frame made of structural parts and press-folded high
resistance carbon steel sheets. It includes hitch locks to be connected to the three points
of the tractor, the coupling of the ridging and unridging set of disks support and the
height
adjustment
wheels.
b.)
Sensing Device Unit
- completely hydraulically operated. It's peculiar con
fi
guration
guarantees
a
speci
fi
c sensitivity of the sensing device rod, which proportionally
controls the cylinder whose function is to avoid obstacles.
c.)
Unridging and Ridging Set of Disks
- are the two main accessories that can be applied
to this equipment. The unridging set of disks removes the soil from the inter-rows.
Particularly suitable even if the speed of travel of the tractor has been reduced or in case
of clay or stony
fi
elds. The set of disks rotation and therefore the soil working is
performed by means of the hydraulic motor operated by the pressure of the oil sent by
the pump to the machine by means of a remote hydraulic valve (see hydraulic diagram
of
the
speci
fi
c three disks device). The ridging set of disks is not hydraulically operated
but rotates because of soil friction and ridges the soil in the inter-rows.
d.) Control
Unit
- to be placed by the operator. The remote hydraulic valves are manually
operated by means of levers, or he hydraulic solenoid valves of the equipment controls
are operated by means of push buttons and by the 12 Vcc tractor outlet.
The set of disks have been designed and manufactured to work inter-rows soils of any plantation, both
vase and hedge trained, as well on close up short trunked plants or young plants. The use of unridg-
ing and ridging set of disks allows to remove the exceeding soil, herb, and damaging plants, to destroy
canalizations made by rodents, to bring again soil and ridge it.
This machine can be used only for the purpose for which it was conceived. Any other employment is
considered improper and the manufacturer cannot be considered responsible for possible damage caused
by the improper use of other uses which are not explicitly speci
fi
ed in this book.
