Machine description
Range of application
HE-VA Euro-Tiller is a trailed seedbed harrow which is available in 6,0m, 7.0m, 8.0m, 9.0m and 10.0m
working width. Euro-Tiller is a standard harrow built up in a strong frame construction with 7 bars and 4
boogie 300/65x12 –depth / transport wheels ensuring precise harrow depth in all soil types. The harrow
depth is easily adjusted centrally on the machine, and the depth wheel master-slave hydraulic system
ensures a uniform working of the wheels. By means of a switch in the cabin, the driver can stop the
electric depth stop enabling the manual operation of the hydraulic depth control. Euro-Tiller has a wide
range of extra equipment, meaning that the harrow can be built up individually depending on the actual
soil conditions and harrow tasks. In front the Euro-Tiller can be equipped with a strong front-harrow in
front of the Spring-Board leveling bar, ensuring that the leveling bar can level the already loosened soil
effectively. At the rear a Spring-Board after-harrow can be mounted followed by a long finger after-
harrow. It is also possible to mount a long finger after-harrow separately. As a novelty HE-VA is offering
a ø400 mm flat bar roller at the rear, leaving the field with a consolidated surface and a perfect surface
finish for a sowing of for example beets.

On all widths, Euro-Tiller has 20 lubrication points. The typical lubrication points are located at spindles,
wheel bearings, wing arms, and the possible rollers have 6 lubrication points. All Euro-Tiller have to be
lubricated after every 30 working hours as well as after the cleaning in order to press out any water and
dirt.
Note! However, the double-sealed ball bearings in the roller should only be lubricated every
20 working hours and by 1-2 strokes so that the sealing rings are not pressed out.
Important! The hydraulic system is filled with oil type Hydro Texaco HD32

Instructions and adjustment of the harrow
All fundamental adjustments must be carried out on a plane surface with the
harrow attached to the tractor and the wing sections lowered.
Attaching the harrow
Euro-Tiller is attached to the fixed tractor drawbar. Attach the
hydraulic hoses. Please note that the hoses with blue dust caps are
for lifting the harrow, and the ones with yellow dust caps are for
wing folding and leveling bar.
Adjusting the top link of the harrow
Lift the middle section just enough to lift the harrow tines from the
ground. Using the top link, adjust the middle section until it is
parallel to the ground. Remember to tighten the lock-nut. The top
link must be greased thoroughly so that fine adjustments are easily
carried out.
Adjusting the support wheels
When the harrow is parallel to the ground, the support wheels must
be adjusted.
The working depth is controlled by 3 hydraulic cylinders which are
series connected in a master-slave system.
To ensure an even depth across the entire working width, the
cylinders must be bled, reset and adjusted in relation to each other in
the following way:
Raise the harrow all the way up, so that the cylinders are fully
extended, and hold the lever in this position for approx. 20 seconds.
In this position, the cylinders’ valves allow oil to flow through the
system and bleed the air out, while simultaneously resetting them.
This operation should be repeated for a few seconds when attaching
the machine to the tractor –after unfolding the wings but before
adjusting the harrow. It should also be carried out a couple of times
during the working day.
Make sure that none of the cylinder pistons are detached when
carrying out adjustments. Position the stop of the master cylinder so
that the harrow tines are lifted from the ground. Adjust the middle
section vertically to align it with the wings by shortening /
lengthening the piston rod (pos.1). If this is not sufficient, the same
procedure can be done on the slave cylinders. Be careful not to turn
too much.
The procedures mentioned above are fundamental: the harrow must
be fine adjusted in the field to ensure a perfect result. The earthworks
1

Euro-Tiller 23-05-2016

being created in front of the leveling bar should be even across the entire
working width.
The piston rod end of the master cylinder should never be extended more
than 30mm (50mm for the slave cylinders) Be sure to tighten all lock-
nuts.
Make a habit of bleeding out the cylinders each time the harrow is
attached to the tractor, before work, as well as a few times during the
working day.
Adjusting the levelling bar.
In the field, when the harrow is lowered into working position.
First, the system must be bled, in the same way as the support
wheels.
Adjust the piston rods (pos. 1) so that the levelling bars are aligned.
The levelling bar on the middle section may need to be adjusted 5-
10mm lower, in order to eradicate the wheel tracks. When the
piston rod end is extended, the leveling bar is raised, and vice versa.
Do not extend the piston rod end more than 20mm.
Make a habit of bleeding out the hydraulic system each time the
harrow is attached to the tractor, before work, as well as a few times
during the working day. It only takes about 15 seconds.
Depth adjustment of the harrow
The depth adjustment is performed by adjusting
the sensor “A” out (smaller working width) or in
(bigger working depth) Loosen the thumbscrew
“B”, move the sensor arm “C” to the right
position and tighten the thumbscrew “B” again.
When the sensor activator “D” meets the sensor
“A”, the valve “E” will cut off for the return oil
and the harrow depth will be locked. By means
of the on/off switch in the cabin, the depth
adjustment can be “oversteered”. That is to say
that the sensor activator “D” can pass the sensor
“A” and a deeper work is possible e.g. on the
headland.
