Single-disc opener - Seeding Disc Hub

Single-disc row-unit, seeding disc hub.

Seeding Disc - This is where we made the biggest and best changes: 

  1. The blade hub was redesigned, now housing DOS TWO LARGER BEARINGS with a higher load coefficient.
  2. New SPLINED SHAFT IS OF LARGER DIAMETER, providing greater tightness thanks to the incorporation of a dust cover that reduces the work of the external lip seals.
  3. A LONGER BUSHING was incorporated into the design, where the splined shaft is housed that extends the guide capacity, giving more solidity to the assembly.
  4. The sealing system of the hub has TWO SEALS, one with external lips and the other conventional, which ensures that in the lubrication process with a grease pump, the seals do not slip due to excessive pressure. It is the only greasing point, ONLY ONCE EVERY 500 HECTARES.

It is the only greasing point. Only once every 500 hectares.

Single-disc opener - Leveling Wheel

No more blockages and breaks. Spend more time seeding.

Rueda rota de caucho

The rubber wheels have very little durability particularly in fields with soybean stubble.


Another very common problem is in soils with excess moisture and large volume of stubble, is the gauge wheel blocking.

The solution to these problems:

Single disc opener for no-till farming - Seeding Disc - A URETHANE GAUGE WHEEL is incorporated as part of the base model, eliminating the previous cleaning conical boron steel extension

We incorporate a semi-pneumatic tire that we manufacture using an anti-friction urethane polymer. We redesigned it using innovative materials for a smooth and self-cleaning operation. It combines technology and functionality to provide exceptional performance in the field.

  1. A URETHANE GAUGE WHEEL is incorporated as part of the base model, eliminating the previous cleaning conical boron steel extension.
  2. A new SIX-SPOKE HUB CENTERwas added.
  3. The hub now has a MAINTENANCE-FREE KRRS double-shielded double-row ball bearing.

Increase your productivity and efficiency in planting with a state-of-the-art regulating wheel.

Single-Disc Opener - Shoe

We made The shoe of ferritic nodular cast iron, and at the bottom of this piece, a contribution of tungsten electrode is made to increase its useful life.

The new design of the shoe, narrower than the previous one, allows a more stable planting depth and less soil removal, preserving moisture, which will allow the crops a quick and uniform emergence, significantly improving their chances of a higher yield.

We designed the shoe to fit the blade, thus preventing the ingress of dirt, straw, etc. and preventing the body from getting stuck.

Single disc opener for no-till farming -seeding shoe

The shoe system has the possibility of being regulated in three height levels. To extend the blade’s life, lift the fuse bolt one notch of the three height positions to compensate for wear.
At the seed’s exit, the fertilizer, together with the blade, generates a chamber inside the groove. This avoids the need for a tab to keep the seed inside the groove, and at the same time, the plastic tail would alter the uniformity and distribution of the seeds.

Achieve efficiency in planting.

Single-Disc Opener - Urethane Firming Wheel

Thinner Than The Previous Ones.

The new URETHANE WHEEL is now narrower and more flexible, so it fits better in the furrow, helping to improve the contact of the seeds with the soil and preventing the seed from making contact with the air and, therefore, the proliferation of fungi. It has a spring that adjusts the pressure according to the terrain conditions.

It has a MAINTENANCE-FREE, double-shielded KYY3 bearing, steel on the outside and a Viton seal unit in the second plane (FKM or vinylidene fluoride). These elements provide more significant tightness and protect the bearing against the ingress of garbage and premature wear.

Single disc opener for No-till farming - Firming wheel protection
We include a plastic cup that houses a very sharp-lipped  FRONT LIP RETAINER, capable of sealing the deformations of the metal sheet, producing an additional hermetic shielding.

On the other side of the wheel, we place a Viton counter-seal that fits on a spacer, which gives the precise height between the arm and the wheel. These improvements prevent the possibility of garbage ingress.

Are you looking for a solution for sowing in wet and sticky soils?

PLASTIC FIRMER TAB: it has an adjustable spring regulator and two fastening screws that are screwed directly into the shoe.

Single-Disc Opener - drop tubes

Single disc opener for no-till farming - Seed and fertilizer downcomers

Optimized seed/ fertilizer-lowering system

We optimise the independent seed and fertiliser lowering system using plastic tubes jacketed 6 cm (2.36 inches) inside the shoe. This system avoids all possible contact with any metal surface, helping prevent moisture condensation phenomena and the consequent fertiliser clogging.
The seed falls vertically by gravity, avoiding needing a plastic tail.

Optimize your planting – Shoes and Tubes without clogging!

Single-Disc Opener - Optimized Capping System

Single-disc row-unit - Closing wheel
The new capping system features a cast iron wheel that has had material removed from its center, which improves the performance of the spring and prevents rebounds. The innovative capping wheel has a KYY3 type bearing with double shielding, MAINTENANCE-FREE and has two indexing angles, one horizontal and one vertical, which allow the soil extracted by the disc and the shoe to be returned to the furrow and achieve precise compaction on the planting line. The wheel arm is cast nodular steel and includes an ergonomic spring that facilitates the adjustment of the working pressure without the need for tools.

Optimize your agricultural production!

Single-Disc Opener - Robust Structure and Better Joints

We machine the main arm in a single operation in a machining centre, eliminating dimensional errors. All structural components are made of ferritic matrix nodular cast iron, which offers excellent resistance to torso bending, allowing the part to resume its original geometry in an extreme overload situation thanks to its elasticity.
As for the wheel, tread and capper joints, significant improvements have been incorporated, such as a treated hub made of high-quality cemented and ground non-deformable steel with a hardness of more than 64 RC, which guarantees its durability.
In addition, instead of placing them flush with the body, they are incorporated 5 millimetres into the interior, and a small-sized seal is housed but has enough capacity to stop the entry of dirt, water and pollutants.

Single disc opener - Main structure

The assembly process includes permanent shaft lubrication that eliminates the need for a lubrication zerk, ensuring optimal performance and increased assembly durability.

Take advantage of the strength and durability of our row-units.

Single-Disc Opener - Row-Unit flange

Better bite against the tool holder bar

Single disc opener for no till farming - Flange

As the seeding disc is inclined 7º, it produces an intense lateral effort trying to move the bodies on the tool holder bar.

We also modified the anchoring system; it now has a flange cover cast in nodular steel. The clamping row-unit flange has a much more aggressive bite on the toolbar to avoid axial displacement.

Take advantage of the strength and durability of our openers.

Single-Disc Opener - Eje Pivot

New Lubrication System.

Single-disc opener main axis

In addition, among the improvements, we include lubrication oil in the pin or shaft of the main joint of the opener, allowing minor maintenance just once a season. Each pump of grease injected by the zerk comes out through tiny holes at the pin ends, generating a trap in the groove that lubricates the joint and works as a retainer. The pin is of non-deformable steel with heat treatments reaching hardness values of 64 Rockwell, avoiding premature wear.

Take advantage of the strength and durability of our openers.

Single-Disc Opener - Compression system

Corrosion Resistance Improvements.

In the case of the compression system, improvements have been implemented in the surface to combat corrosion.
The pressure unit maintains a spiral system of very high hardness, capable of resisting up to 300 kilos per body per seeding line. A bolt with a washer indicates the working pressure by generating light between the washer and the casting body. The greater the light (space between), the greater the pressure.
Corrosion resistance is an important aspect and not only aesthetic. We use chrome plating throughout the separator, stud and flange package, and dual-component polyurethane paints with a furnace flash stroke to ensure excellent corrosion resistance. This improvement provides a better yield and a longer service life for the opener.

Protect your investment with our corrosion resistance system.
