3.4 FOLDING FRAME
3.4.1 DESCRIPTION OF FUNCTIONING
The machine frame is designed so that the side ends that hold
the planting elements can be folded using a hydraulic system,
thus reducing the road.
DANGER
When opening and closing of the folding frame, do not under
any circumstances stand close to the machine.
In order to use correctly the toolbar of the planter, operate as
follows:
1)
Hook the planting unit to the tractor three-point coupling using
suitably sized pins equipped with the necessary safety
devices (retainer clips, spring pins, etc.).
2) Connect the planting unit hydraulic pipes to the tractor
distributors.
3) Before switching the machine on, make sure that there are
no people, children, animals or any object that could get in
the way of the machine, and ensure that there is excellent
visibility in the area of operation.
OPENING
4) Unhook the safety pins on the frame (A, Fig. 12) and place
them in their relative seats (B, Fig. 12).
5) Check that the hydraulic pipes are correctly connected.
6) Actuate the hydraulic system to open the frame, keeping the
planter raised from the ground.
CLOSING
7) Activate the hydraulic system to close the frame, keeping the
planting unit raised off the ground and with the seeders
hooked into the raised position.
8) Hook the frame safety pins into their relative seats (A, Fig.
12).
9) Discharge the pressure in the hydraulic system and
disconnect the hydraulic pipes.
3.4.2 FLOATING FRAME
A floating system for the furrower holding frame has been
incorporated in the planter: in specific ground conditions (valleys,
hill planting etc.), this system facilitates even planting of the
seedbed, despite its irregularity.
In these conditions, the support wheels must be fitted at the
ends of the side frames (Fig. 13). During the normal planter
setup procedures, the support wheels have to be adjusted for
height, varying the position of the pin (C, Fig. 13), in order to align
the furrower-holding frames and guarantee an even sowing
depth.
