Vaderstad Rollers Brochure - LiveUpdater

Better tillage methods
The main operations of the Rexius roller are crushing clods
and levelling ploughed land. By equipping the Rexius roller
with Crosskill rings and the Crossboard you are in command
of a superior soil preparation system of the highest calibre
available. Even on the toughest soils the Rexius roller still
creates an excellent tilth as a part of various tillage combinations.
In these extreme conditions it is highly recommended
to use the stabilising rod for producing the best level finish
possible. The heavy duty Crossboard levelling board can be
locked together with stabilising rod and can be equipped
with Single-Knife.
Levelling efficiency
The Rexius rollers and tool-bars have been developed with
the Rapid tillage concept in mind and versatility available
with this range will virtually suit all of your requirements.
Hook your Rexius Roller behind your cultivator and you
have a valuable tillage train.

Hang the roller on behind
A following Crosskill roller combines
efficient tillage with uniform
soil firming and few passes, equally
relevant in both spring and
autumn. Thanks to the Crosskill
rings, the roller has a unique ability
to keep clean even when the soil is
relatively wet, as is often the case
immediately after cultivator, stubbble
cultivator or disc tillage. This
makes the roller a versatile multitasker.
Roll after spring sowing
Rolling in the spring after drilling
with the Rexius roller equipped
with Crosskill rings ensures stones
are pushed down into the soil, and
that optimal conditions are created
for germination around the seed.
The surface is also left in a porous
state, which prevents silting-up
after heavy rain.
Roll autumn-sown crops in
spring
The unique design of the Crosskill
rings helps to break up capped
autumn drilled soils in the spring,
and exposes delicate root systems
to the air to stimulate growth.
Stones are also pushed beneath the
soil surface.
Large stone trays
With two stone trays on each side,
rolling can be accompanied by efficient
stone lifting. The stone trays
are very roomy since each can hold
more than 1000 litres. This allows
the driver to concentrate on the
task of rolling rather on constantly
reversing out to the edge of the
field to empty the stone trays. A
small detail that further increases
capacity on busy days. When the
stone trays eventually fill up, the
entire roller is simply tipped back
in a suitable spot and the trays are
emptied. All this is done hydraulically
from the tractor cab.

Folding or unfolding
– both are easy
The change between transport
and field work is strikingly
simple and can be
effected without the driver
having to leave the tractor
cab. The transport locks on
the rollers are automatically
engaged and released during
folding and unfolding.
Unfolding to working mode
1. The central section is lowered
and the transport locks released
2. The tractor is reversed
3. After a few metres, the roller is
unfolded and lowered forward
4. Ready for work
8. The roller is automatically locked
and is ready for transport
7. Drive the tractor forwards 6.Tilt the roller 90° backwards 5. Stop the tractor
and back to transport mode

Rexius Packer broadens the horizon
A Rexius Packer after a Cultus stubble cultivator or an NZ-cultivator
crushes clods and firms the soil efficiently. In stubble tillage,
this soil firming produces optimal conditions for the germination
of weeds and volunteer plants. In a second pass with a
stubble implement, these are effectively eliminated. On ploughed
soil, Rexius Packer crushes clods and levels the surface so
that the best possible conditions are created for the new crop.
Attached by its long towbar, the Rexius Packer follows
smoothly behind the toolbar during work and transport.
Thanks to Väderstad’s patented folding system, the Rexius
Packer has a transport width of only 3 m.
Rexius Packer is available in 5.0 and 6.0 m widths.

Rollex rollers are among the vanguard in
Väderstad’s comprehensive range of soil
tillage and drilling equipment
The first Väderstad rollers were manufactured back in 1977
and the Rollex range saw the light of day in 1986.
Simple and ingenious
Since 1977 there has been a continuous stream of improvements.
The construction of the Rollex rollers has been refined
over the years and is now both simple and ingenious at
the same time. Rollex rollers are of the highest quality. The
rubber mounted bearings give the rollers a gentle and
smooth ride while increasing the lifetime compared to
rollers that do not have this rubber based suspension
system.
Even rolling performance
The loading is uniform on each section of the roller, which
produces a rolling effect that is even across the entire
working width. The Rollex roller provides the foundation on
which to build the harvest!

Broad area of use
The Rexius roller is a heavy and universal roller with a
broad area of use. The roller can be used with the
equipment Crossboard levelling board both in spring
and autumn for preparing a seedbed or as an ordinary
roller after spring drilling. Hook your roller behind the
cultivator, disc implement or the stubble cultivator -
there are a lot of combination possibilities.
Economical and biological advantages
The Rexius roller is complimentary to most other
implements. This provides a greater level of intensity
and productivity with every pass across the field creating
extensive savings of time and costly energy while
also reducing traffic.The reduction of passes from the
time of combining through to establishing a new crop is
biologically and economically advantageous. Not only
is the cost of tillage reduced but also the time requirement.
The soil is therefore less compacted and both
spring and autumn sowing can often take place earlier.
This will also result in increased permeability of water
due to greater pores, which are invaluable in early
droughts.

The Rexius 1230 is a large roller ideal for farmers who
place high demands on capacity and work rate, but
who are not prepared to compromise on the quality of
their rolling. The large roller is heavy and does a first
class job even at high rolling speeds. Thanks to the
unique rubber suspension in which every roller
section is mounted, the roller has a ‘floating’ ride and
unique stability and durability. The rubber suspension
absorbs and ‘swallows’ impacts and vibrations that
would otherwise be transmitted through the bearings
and cause unnecessary wear, with breakages and
stoppages as a result.
The importance of rolling for many farmers is well documented
through years of experience. Rolling is effective
in giving uniform emergence after spring drilling, firming
in winter crops in the spring, producing good soil/root
contact and pressing down stones that can otherwise
cause problems for the combine during harvesting.
Rolling direct after ploughing is another task for a powerful
roller that can save many later passes with other
tillage implements. With the new working width of over
12 metres, the Rexius 1230 fits in perfectly on farms
where 12 or 24 metre tramlines are being used in field
operations.
The Rexius 1230 is constructed on the same principles as
the other members of the Rexius range. This means a
very robust and powerful construction with strong joints
and framework. The weight is over 450 kg per metre
working width, compared with 400 kg/m for previous
Rexius rollers.

Contouring
The roller sections are freely jointed relative to each
other and the construction allows large ruts in the field
to be dealt with while still maintaining the good contouring
ability. The weight of the roller also contributes to
the excellent contouring at high driving speeds.

Protect emergence
Crop production advisor Henrik Lillje in a trial on hard crusts at
Brunnby Research Farm outside Västerås, Sweden, at the boundary
between an untreated plot and a plot where the crust was
broken using a Rexius roller with Double-Knife attachment.
Rain between drilling and emergence can completely
compromise crop emergence if a crust forms. In that
event, a rapid and determined response is needed to
protect emergence and ensure crop survival. Two
trials at Brunnby Research Farm in Sweden in 2003
showed the importance of always breaking up a crust.
The spring began well at Brunnby and the barley on
both fields was drilled on 23 and 25 of April. The foundations
were laid for a good harvest. Then came the
rain and within the space of 10 days over 50 mm of rain
had fallen.
Two types of crust
On soils with a silt component, a crust always develops
as a predictable reaction to rain after drilling.
Everyone knows that. But few actually know how much
yield loss this crust causes, since it is difficult to get
reliable measurements. Therefore during an advisory
field visit at the beginning of May, the idea arose of
measuring the impeding effects of such a crust. Two
trials were laid out on different soils. One of these was
a heavy clay with 3.4% humus. On this, the crust that
developed was brittle and crisp.
‘You could see footprints when someone walked on the
soil’, explains Henrik Lillje, crop production advisor for
a Swedish agricultural advice service and the initiator
of the trials.
The other soil was a poor medium clay with only 1.9%
humus but with a large silt fraction.
‘Here the entire seedbed became a compact crust’ says
Henrik Lillje.
Four treatments
Four treatments were applied in addition to the untreated
plot. A Rexius roller with Crosskill rings was used
with and without the crust-breaking Double-Knife
attachments mounted on the levelling board. In addition,
an ordinary NZ cultivator and a converted Wiberg
cultivator with three rows of following harrow tines
were tested. All treatments were carried out on 15 May
and their effects were soon apparent.
‘The trapped seedlings began to grow again when we
aerated the soil with some form of treatment’, reports
Henrik Lillje. And when the time came to harvest the
barley, the summer recovery was apparent in the
combine bins in the plots where the crust had been
broken. In the trial with the brittle crust, all treatments
produced a 14 - 15% yield increase.
‘The yield outcome was better than we expected. The
results show that one should always take action as
soon as crusting is suspected’, advises Henrik Lillje.
Crop failure prevented
In the trial with the hard crust, the improvement was
huge and the yield increased from the crop failure level
to almost a normal level in some of the plots. The conclusion
is that it is better to do something than to wait
and do nothing at all.
‘The essential thing is to improve gas exchange for the
seedlings trapped under the crust’, explains Henrik
Lillje.
The best results were obtained with the crust breaking
Double-Knife tool, which had to face this stiff challenge
in only its first year on the market.
‘The crust-breaker knife is an excellent crust-breaking
tool. The advantage with Double-Knife is that it is
possible to apply hard cultivation without ripping up
the soil because the movement is directed frontwardsbackwards’
comments Henrik Lillje.
Rexius surprising
The NZ cultivator was poorly set up and should have
gone deeper, so it did not do itself justice. However, the
excellent abilities of the Rexius roller emerged even
without the crust-breaking Double-Knife on the levelling
board.
‘One pass with the Rexius roller only made faint tracks
on the surface but more than doubled the yield!’
The best advice for growers is to always react in some
way and to never delay.
‘Always break up a crust – hit it hard with whatever is
available on the farm’, concludes Henrik Lillje.

Rubber suspension
The rubber suspension is a unique
construction from Väderstad that
gives the roller unbeatable durability
through the ability of the
rubber to absorb vibrations and
impacts. The rubber suspension is
very hard-wearing and maintenance
free.
Multiple sealed bearings
The bearings are designed and
manufactured for long life under
tough conditions. The bearings are
mounted in a rubber-sprung
bearings chamber. The bearings
have multiple seals and can be lubricated,
for long life in dusty and
demanding environments. The roller
axle, which is 55 mm in diameter, is
manufactured from microalloyed
steel of high quality.
Hard metal bushes in
joints
All wing joints are equipped with
hard metal bushes and hardened
joint bolts. The whole joint can also
be lubricated for an unrivalled
length of life. The joint is also wide,
with large joint surfaces to reduce
the load on the materials.
Robust frame
The basic frame is constructed
around heavy rectangular profile
steel with dimensions 200x100x6
mm and with a high steel quality.
The rigidity is impressive and
imparts great stability to the
construction. The entire frame is
all-welded to avoid having loose
bolt connections exposed to the
wear that can occur during high
speed work.

BioDrill
With BioDrill on a Väderstad roller,
grass leys, catch crops and other
small-seeded crops can be drilled.
This saves passes, time and money.
The seeds are metered out by the
tried and tested Fenix system with
great precision. The seed nozzles
are placed in front of the roller unit
and give uniform broadcasting. The
seeds are buried by the roller in the
upper 2 centimetres, where the
conditions for germination are
best.
Automatic locking device
The locks open automatically when the
central section of the roller is lowered.
During transport, when the central
section is raised, the locks engage and
prevent accidental unfolding of the
roller during reversing.
Rigid stabiliser
The powerful Crossboard levelling
board has a heavy stabiliser bar of
very high spring steel quality with a
breaking point of over 1100 N/mm2
and provides a very thorough
levelling effect on even the heaviest
and most difficult clay soils.
Single-Knife or
Double-Knife
To further enhance the cultivating
and crushing effect of the
Crossboard, it can be fitted with
sharp, hardened steel blades called
Single-Knife. The crust breaking
Double-Knife blades break through
the surface pans that readily develop
on silty soils after heavy rain.
The most efficient crust-breaker
available for a very light surface
‘cracking’ is a pass with only the
Crosskill rings working.

Cambridge rings
The conventional Cambridge rings are best utilised
when the Rexius roller is mostly working as a traditional
roller e.g. after drilling or when pressing down
stones.
Heavy Duty rings
During autumn conditions a heavy duty ring is more
suitable on heavy soils or when a high degree of consolidation
is required. Heavy duty rings are widely used
throughout the continental Europe.

Crosskill rings
Crosskill rings have become very common because they
do not only have the same properties as the Cambridge
rings, but they also possess a range of additional and
unique characteristics such as: They leave a loose and
crusting-resistant soil surface, they crush clods efficiently,
they are less likely to become clogged by wet soil and
they ‘swallow’ light soils much better without leaving a
puffy seedbed.

Steel ring for Rexius Packer
The hardened steel ring on the Rexius Packer efficiently
firms the heaviest soils. On ploughed soil, clods are
crushed with impressive power and a levelled seedbed is
produced. The ring has particularly good abilities in wet
conditions thanks to efficient scrapers. The steel rings
are tightly screwed together on the axles and each ring
acts as an effective disc spring, which makes any subsequent
adjustment unnecessary.
The manufacturer retains the right to alter any specifications and design without notice. Patented and patents pending.
