Hydraulically foldable devices consist of a central load-bearing main frame with a 3-point connection for the tractor hitch and two hy-
draulically foldable tine frames. When folded up, the tine frames must always be secured against unintentional opening, for this purpose
a mechanically operated shut-off valve is installed on the hydraulic coupling plug of the corresponding control circuit. In the special
equipment variant „remote-operated shut-off valves“, permanently locked shut-off valves are installed on the two hydraulic cylinders,
which can be opened by pulling the unlocking rope. As soon as the unlocking rope is released, the valves automatically switch to the
locked state.
HYDRAULIC FOLDING MECHANISM
(TERRAKAN 5000, TERRAKAN 6000)
Make sure that the hydraulic control circuit is only unlocked for the active folding process.
For safety reasons, the folding mechanism must be locked during transport and field work.
¾
Make sure that there are no people / animals in the danger
area.
¾
Only approach the device when the hitch is lowered and the
device stands securely on the ground.
¾
Open the shut-off valve on the hydraulic coupling plug.
¾
Lift the device at least one meter off the ground via hitch.
¾
In the case of devices with chassis, lift the tractor‘s hitchin in
addition to the hitch system of the device.
¾
Make sure there is sufficient space between the machine com
-
ponents and the ground during the entire folding process. Vari
-
ous components can be severely damaged in a collision.
¾
With the „remote-operated shut-off valves“ equipment, the un
-
locking rope must be pulled during the entire folding process.
¾
Apply pressure to the hydraulic control unit until both tine fra-
mes are lowered and have reached the end position.
¾
After the folding process, lock the hydraulic circuit using a shut-
off valve (if the option remote-operated shut-off valve is instal-
led, the device is automatically secured against unintentional
opening as soon as you release the actuating rope).
¾
Make sure that there are no people / animals in the danger
area.
¾
Only approach the device when the hoist is lowered and the
device stands securely on the ground.
¾
Open the shut-off valve on the hydraulic coupling plug.
¾
Lift the device at least one meter off the ground via hitch.
¾
In the case of devices with chassis, lift the tractor‘s hitchin in
addition to the hitch system of the device.

Make sure there is sufficient space between the machine com
-

-
ous components can be severely damaged in a collision.
¾
With the „remote-operated shut-off valves“ equipment, the un
-
locking rope must be pulled during the entire folding process.
¾
Apply pressure to the hydraulic control unit until both tine fra-
mes are fully raised and have reached the end position.
¾
After the folding process, lock the hydraulic circuit using a shut-
off valve (if the option remote-operated shut-off valve is instal-
led, the device is automatically secured against unintentional
opening as soon as you release the actuating rope).

TRANSPORT POSITION & WORKING POSITION
Before switching from field work to road transport, some machine elements have to be brought into the transport position in order to adjust
the width and height of the device to the requirements of road transport.
¾
Fold the side plates into the transport position (see chapter side
shields).
¾
Fold the side levelling tines into the transport position (see chap-
ter Edge levelling tines).
¾
In the case of foldable devices, position the front roller so, that
when the machine is folded, the transport width of the roller it is
less than the transport width of the tine fields (see chapter front
roller).
¾
In the case of foldable devices, position the vibroboard so, that
when the machine is folded, the transport width of the vibro
-
board it is less than the transport width of the tine fields (see
chapter vibroboard).
¾
In the case of foldable devices, position the rear roller so, that
when the machine is folded, the transport width of the rear rol
-
ler it is less than the transport width of the tine fields (see chapter
roller and straw harrow).
¾
Before entering public area, make sure that the control circuit
for the folding device is locked.
¾
Fold the side plates into the working position (see chapter side
plates).
¾
Fold the side levelling tines into the working position (see chap-
ter side leveling tines).
¾
Make sure that all bolts are secured with a pin or spring pin
before starting field work.
Working position
¾
For devices with chassis, make sure that the control circuit for
the hitch system is locked.
¾
Make sure that all bolts are secured with a pin or spring pin
before starting the transport journey.
¾
Make sure that the lower links of the towing vehicle have to be
locked against sideways swinging before transport. The device
could swing up at higher speeds or when cornering with freely
swinging lower links.
¾
Before driving on public roads, make sure that you comply
with the country-specific road traffic regulations.
¾
Always observe the regulations of the legislator.
