Machine description
Range of application
HE-VA Triple-Tiller stubble harrow is available in 3,00 m and 3,50 m working width as rigid models and
4 m and 5 m working width with hydraulic folding (transport width 3,00 m). All models are available as
lift-mounted or trailed with a row spacing of only 25 cm. The 3 rows of tines are mounted on a solid
frame at a height of 85 cm and with 70 cm interval. The tine spacing is 75 cm.
Triple-Tiller is supplied standard with 75x12 mm reversible and adjustable wearing points, and the
unique double-spring tine, preloaded for 455 kg. The "Quick change system" is available as extra
equipment, and with the choice of chisel points or 260 mm wide wing shares. Behind the harrow section,
the Triple-Tiller has disc eradicators –or the optional tine eradicator - both with centre spindle

Delivery check
Preparation of the machine
Check :
the machine for any damages.
for transport damage to the paint.
hydraulic hoses for cuts and other damage. Check that none of the other hydraulics components
were damages during transport.
that the frame has not been damaged.
that the transport wheels are secure and in good condition.
air pressure level according to technical specifications.
that all wearing points are intact.
that all distance clips for depth adjustment are included.
that all light systems are in working order (if any such system is mounted).

Check the torque:
wheel bolts 386 NM
mounting plate for towing eye
6 pcs bolts 541 NM
Check machine functioning (tractor needed):
raising –lowering –hydraulic unfolding
spindle adjustable levelling discs / levelling tines
spindle adjustable support wheels
rollers / scrapers

Safety instructions
Do not start-up the machine if there are persons in exposed positions** within a hazardous area*.
When persons are in exposed positions (e.g. in connection with adjustment, maintenance, attachment and
uncoupling), the following conditions must be observed:
1. The machine must be lowered to firm ground.
2. The hydraulics must be relieved.
3. The tractor must be stopped and the key removed from the ignition switch.
4. The driver must ensure that no persons are staying in exposed positions during the operation.
* Hazardous area: On and under the machine within a distance of 10 m from the machine.
** Person in exposed position: Any person who is staying wholly or partly within a hazardous area.
Most accidents that happen in connection with the operation, transport and maintenance of machines are
caused by non-compliance with the most elementary safety conditions.
Therefore it is vital that anybody working at the machine carefully complies with the safety instructions
as well as other instructions applying to the machine.
The machine may only be operated, maintained and repaired by persons, who are familiar with this work
and who are further familiar with the possible elements of danger with this particular machine.
ATTENTION !! Rotary parts and loose clothes are a dangerous combination.
IMPORTANT !! In connection with the risk of parts falling down, it may endanger the lives of
persons staying on the base frame of the machine, when it is operated attached to
a tractor.

Safety and instructions for hydraulics
1. The maximum working pressure is 225 bar.
2. It is advisable to label the attachment parts at hydraulic connections between the tractor and the
tool in order to eliminate incorrect operation!
3. When checking for hydraulic leaks, use suitable safety wear (eye protectors, gloves, etc.)
High-pressure hydraulic oil may penetrate the skin and cause dangerous injuries.
In case of injury, consult a doctor immediately. RISK OF INFECTION!
4. Before operating the hydraulics, lower the machine to firm ground.Relieve the hydraulics, stop the
motor and remove the ignition key.
5. Check the hydraulic hoses on a regular basis, however, every six months as a minimum due to any
cracks, wear and tear, etc. Replace any defective hoses immediately.
The life of hydraulic hoses is maximum 5 years.
New hydraulic hoses must meet the manufacturer's requirements.
TRANSPORT ON PUBLIC ROADS:
Check before transport on public roads that the attachment of the machine at the tractor is in accordance
with the local rules and regulations in force (permitted total weight, permitted axle load, transport width,
lights, warning signs, brakes etc.).
FRONT AXLE LOAD:
After the attachment of the machine and at maximum load, the driving properties of the tractor must be
ensured. Check that the front axle is sufficiently loaded. As a minimum, the front axle load must be 20%
of the tractor weight. Permitted axle load and permitted total weight for the tractor must always be
observed.
NB! The driving, controlling and braking properties are affected by the attached machine
combination.

Labels on the machine
There are several labels on the machine advising on safety precautions and practical use.
Please study these instructions carefully, and make sure the operator are familiar with all labels and safety
instructions. Keep the labels clean and legible –if not, they should be replaced.
Explanation:
APlate with number and year of manufacture.
BStudy the safety instructions carefully before operating the machine,
and observe all safety precautions.
CTighten up all bolts regularly.
If this is not done, our warranty obligations will no longer apply.
DEnsure correct hydraulic pressure for release system.

Start-up
General information
Rigid models require 0 –1 double-acting oil outlets (see technical specifications p. 5)
Attachment (rigid lift-mounted machines)
1. Reverse the tractor to the machine and attach it.
2. Lift the machine to maximum transport height.
Uncoupling (rigid lift-mounted machines)
1. Lower the machine onto level, firm ground, and release all hydraulic hoses.
2. Lower the support leg.
3. The machine may now be uncoupled.
Attachment (rigid trailed machines)
1. Reverse the tractor to the machine.
2. Fasten all hydraulic hoses on the tractor outlets.
3. Apply pressure to the drawbar-wheel cylinder until the drawbar reaches the right height.
4. Reverse the tractor and attach the machine.
5. Lift the machine to maximum height and lift the support leg.
Uncoupling (rigid trailed machines)
1. Lower the machine onto level, firm ground.
2. Lower the support leg.
3. Adjust the drawbar-wheel cylinder (red), so that the drawbar pin is loosened
4. The machine may now be uncoupled.
5. Move the tractor slightly forward to relaese all hydraulic hoses.

Settings and adjustment
Roller depth adjustment
The machine is delivered including coloured distance clips (pos. 1)
These clips are easily removed by hand to adjust the working depth of the roller.
When not in use, excess clips may be put onthe tube (pos. 2).
Scraper
Triple-Tiller is fitted with scrapers of special steel
in between the rings of the V-profile roller.
Check their centering daily, so they do not wear
unnecessarily, and to ensure optimal effect.
The correct height adjustment is 1-2 mm from
the bottom of the roller.

Maintenance
After the first 10 hours of operation, all bolts must be tightened,
(see torque diagram, page 9). Hoses, fittings and cylinders must be checked for possible leaks and
further tightened.
Check regularly that all bolts are tightened.
After the season all lubricating points must be lubricated, then wash and lubricate the machine. Do
not use high-pressure water directly on ball bearings. After washing it, you may spray the machine
with a rust preventive oil.
Lubrification
When lubricating, maintaining and repairing the Triple-Tiller, always lower the machine, brake the tractor
and stop the engine.
The typical lubricating points are: by the roller, spindle, side section and the arms of the roller bar. The
lubricating points must be lubricated after 10 hours of operation, and before/after cleaning in order to
drive out any water or dirt. The lubricating points are placed by movable parts, as well as by the ball
bearings and cylinders.
Note! The double density ball bearings in the roller should only be lubricated every 20 hours,
and with 1-2 strokes so as not to press out the sealing rings.
IMPORTANT! The hydraulic system is filled with oil type Hydro Texaco HD32
