Constraints to use
Descriptions of what the machine can and cannot be used for:
•Can only be used for breaking down sowing beds on agricultural land under cultivation. Areas
worked must be in normal agricultural maintenance, i.e. with no significant unevenness or holes.
•The machine can only be used towed behind an agricultural tractor, and must be connected to the
tow bar.
•Maximum working speed is 15 kph. But always adapt speed to the nature of the area to be
worked.
Use of the machine which does not fulfil the conditions above will be regarded as non-authorised,
and will invalidate the factory guarantee.

Description
Construction
CULTITRAIL is a robust 5-bar, towed sowing bed harrow, with the following construction:
•The harrow consists of 3 sections. A centre frame which is identical on the 5 and 6 me-
ter models. And 2 wings, which can be hydraulically folded to achieve a transport width
of 2.5 metres.
•The harrow tines are 8 cm apart across the full working width.
•The frames are designed so that the tines are in an offset pattern with a 400 mm gap
between each tine. This ensures good soil penetration.
•CULTITRAIL has a heavy-duty crackerboard at the front to level the soil and crush clods.
The crackerboard depth is hydraulically adjustable from the tractor cab.
•Harrow depth is controlled by the 4 large wheels which are steered by a hydraulic sys-
tem to ensure the same depth is always maintained. A simple mechanical stop mecha-
nism on the 2 centre wheel cylinders provides depth regulation without the use of tools.
•The harrow is designed to lift the entire frame parallel to the ground. Along with a lifting
height of almost 400 mm, this means the tractor can reverse with the harrow without
risk of damage.
•The harrow can be fitted several different types of post-harrows or packing rollers. A
rear-mounted levelling board can also be mounted with these.

Construction with pin stop
Fig. 2
All pins on the machine have square heads. The
frame elements they fit in also have a pin stop (A).
Pin length allows the pin to be inserted fully, allow-
ing the pin stop to prevent the pin from rotating
when the machine parts move in relation to each
other. This construction ensures that the pins bear
the brunt of wear and tear, rather than the frame.
Low maintenance costs and long service life are
the result.
Hydraulics to raise/fold side sections
Fig. 3
Hydraulic cylinders (A) and (B) are linked to the
same hose via a T-piece. Folding out requires min.
pressure in cyl. (B). Lock (C) is therefore lifted free
of pin (D) before the side section is pressed out-
wards/downwards. Throttle nipple (E) controls
lowering speed of the side sections when they
pass the point of gravity. Cyl. (B) has an internal
spring which retracts it as soon as the hose is de-
pressurised. The lock automatically engages
around the pin when folding up. Use stop screw (F)
to adjust side section transport position. Side sec-
tions are factory-set to be fully symmetrical in
transport position to ensure the lock engages
when meeting the stop screw. The side sections
are thus completely locked into place for
transport.

Hydraulics for levelling board and wheel frame
Bleeding the system
If the machine has not been used for some time, air can get into the system. This can cause one or both
side sections to not reach the same working depth as the centre section. Bleed the system by moving
the spacer blocks (E) on both cylinders to the side, so that the cylinder can fully retract. The cylinders
are designed to allow the oil to pass over the ram through a channel when fully retracted. The harrow is
then fully lowered using the tractor hydraulic system. Hold the handle in lower position (not flow posi-
tion!) for a several minutes after the cylinder has fully retracted, even if using the tractor's over-
pressure valve. The system will now be bled.
The hydraulic cylinders for the front levelling board are linked in the same way. Use the same proce-
dure for bleeding.
Fig. 4
The hydraulic cylinders (A) are linked in series with the cor-
responding wheel frame cylinder on the side section. When
the wheel frame is raised, the tractor pumps oil to (B) the
centre cylinders. The oil which then flows out of (C) is linked
to (B) on the side section cylinder. As the cylinders have
free ram shafts (D), the amount of oil moved on each side of
the ram is identical for any given movement. This ensures
that the side cylinders move to exactly the same extent as
those in the centre. A depth stop is therefore only neces-
sary on the two centre cylinders. The side cylinders auto-
matically maintain the same working depth.

Setting up
CULTITRAIL comes with factory settings, but must be finely adjusted before use.
Numerous adjustment options make the machine more flexible and ensure maxi-
mum use.
Basic setting
Fig. 7

To achieve uniform effect on
the soil, it is important that
the main frame is horizontal
when in use.
Adjustment is made using the
top bar (A). Extend to raise
the front end of the harrow
frame.
Remember to tighten the re-
verse thread wing nut (B)
when adjustment is complete.

If the harrow is raised, the weight on the top bar will be very heavy. Lower before
adjusting top bar. Adjustment can be made easier by pressing the front cracker-
board hard into the soil using the tractor hydraulic system.
Working depth
Fig. 8
Adjust working depth
using the hose length
limiters fitted on the 2
wheel-lift cylinders on
the centre wheel frame.
The spacer blocks (A)
can be swung in front of
the lift cylinders.
Raise the harrow to free
the spacer blocks.


Only the two centre lift cylinders need to be adjusted for depth, as the two outer
cylinders are slaved to the centre cylinders. See "Description" for details of system
construction.

To achieve uniform working depth on both sides, it is important that the same
number of spacer blocks limit both lift cylinders. Each block adjusts working depth
by approx. 15 mm.
Always comply with the safety instructions when inserting/removing spacer
blocks.
Side pull
If the machine shows a tendency to pull to one side, use the wheel cylinder sus-
pension brackets on the side sections to adjust. Adjustment procedure: Example: if
the machine is pulling to the right, lower the wheel cylinder bracket on the right
side section a little. This will raise the entire side section a little, counteracting side
pull. The setting only needs to be made once - and only if side pull is occurring. The
setting option is standard on machines with serial numbers higher than 00127.
New adjustable cylinder brackets can be supplied for older models if side pull is oc-
curring.
Fig. 9
Wheel cylinder bracket (A) on the side
sections has oblong bolt holes. Slack-
en the bolts and adjust bracket down-
wards. Tighten bolts. Bracket and
chassis frame have a tooth (B). When
both teeth are aligned, the bracket is
in its standard setting = lowered to
maximum.

Wheel scrapers
Fig. 10
The harrow wheels determine the har-
row depth. It is therefore important
that they are kept clean. All wheels are
therefore fitted with wheel scrapers
(C). The scrapers are adjusted close to
the tyres, yet still allowing the wheel
to turn a full circle without touching
the scraper.
Adjusting crackerboard
Fig. 11
The foremost implement, the cracker-
board, is fully hydraulically adjustable
from the tractor. Depth is shown on the
indicator (A), which is visible from the
driver's seat. The crackerboard hy-
draulic system is fitted with a throttle
to ensure smooth, even movement
regardless of the amount of oil coming
from the tractor.

The board is not intended to work as a dozer blade, to avoid dragging large
amounts of accumulated soil. This increases fuel economy and saves wear on the
tractor and machine.

Operation
Correct operation is vital for optimum use. This applies to working in the field and
for safety.
We recommend running at a slight angle to the sowing direction for the final pass
for the best results.

Adjustment of the main frame to keep it horizontal may be necessary after adjust-
ing depth.
Extending and retracting
The machine must be parked on a level surface for extending and retracting. This is
important for safety reasons, and to ensure the transportation locks engage.
Before the machine can be extended or retracted, the tractor driver must ensure
there are no personnel near the machine. Otherwise, there can be a risk of injury.
Extension
Fig. 12
Activating the hydraulic handle (red)
for extension and retraction releases
the automatic transportation lock, and
the side sections will extend.
When the side sections are fully ex-
tended, set the hydraulic handle (red)
to flow position.

The hydraulic handle for extension and retraction must be in flow position when
working in the field, allowing the machine to follow the lie of the land without af-
fecting performance.
