Our Rotors and Discs

Our Rotors and Discs - our Technology and Innovation

OUR TECHNOLOGY, OUR INNOVATION:

Oliver Agro was the first company in the world to produce steel rotors for weeding machines, developing further unique models for long-lasting but also effective use:

  1. Rotoblizz
  2. Rotovert
  3. Dischi Colibrì
  4. Rotoclean
  5. Rotodisk

Weeding breaks up and remixes the surface layer of soil in the inter-row in order to achieve certain benefits, such as:

1. the breakdown of the surface crust, to interrupt the vertical capillarity that is created in the soil after prolonged dry periods and aggravates the water deficit condition;

2. in the opposite case of rainfall, a more uniform incorporation of meteoric water, benefiting a better absorption of the upper part of the root system and a reduction of surface runoff, which is one of the causes of erosion;

3. effective mechanical weeding, which is a viable alternative to chemical weeding by eliminating and reducing its application and thus its cost.
Our weeding machines combine these benefits to the benefit of the crop and production.

Our machines can be equipped with Kit 4.0 with connectivity and customized work data tracking.

3-IN-1 WEEDING MACHINE OFFER: MECHANICAL WEEDER, AERATOR, RIDGER

Our revolutionary concept: an inter-row weeder that combines three indispensable actions for mechanical weed control for greater crop well-being!

  • inter-row mechanical weeder/weeder
  • aerator, as a weed-breaker
  • ridger – tamping machine

Thanks to steel rotors we work directly over the entire surface even very close to the plant, without harming the root and leaf system, eradicating weeds thus reducing the need for chemical herbicides.

 

Advantages of using our inter-row weeders:

  • Less chemical herbicide requirements; mechanical control against weeds;
  • Designed for organic or zero residue crops;
  • Crust-breaker, to aerate the soil and prevent asphyxiation of the plant root system.

 

An original and unique innovation because:

  • Reliable, for precision and durability
  • Multifunctional, as it incorporates 3 machines in one
  • Revolutionary, as it operates between plants and between rows
  • Flexible, as it is easily adjustable
  • Unique, inimitable, with an international patent
  • Practical, and easy to use
  • Customizable for all soil and crop types
  • Economical, because it decreases work time and contains/eliminates weeding costs

Technical features

ROTOBLIZZ

Rotoblizz rotors work directly on the row of plants without damaging the roots or leaves
due to their round shape.
The anti-intrusion reinforcement rod welded inside the rotor allows even heavy, stony soil to be worked.
Rotating counter to each other at the same depth of 3–4 cm, they keep the plant straight, pushing the top of the soil
towards the centre of the row and breaking it into pieces. In the meantime, the blades rotate to move weed sprouts or the weeds
themselves outwards.
They are made of steel and have a fixed inclination of 28 cm towards the plant. They rotate due to a sealed
bearing and are welded with curved, hook-shaped blades with a width of 3 cm

ROTOSARK – ROTOHEMP – MINITRACTOR EL FURBO 

Rotovert

Rotovert rotors, that is, vertical rotors, act like Rotoblizz rotors, but can be used on narrower inter-row spaces due to their shaped profile: 13–45 cm.
Rotating counter to each other at the same depth of 2–3 cm, they keep the plant straight, pushing the top of the soil towards the centre of the row and breaking it into pieces. In the meantime, the blades rotate to move weed sprouts or the weeds themselves outwards.
They are made of steel and have an inclination that is adjustable in 5 positions from 67° to 42° towards the plant. They rotate due to a sealed bearing and are welded with curved blades with a width of 3 cm.
Usable working surface area from the plant 4,5-5,5 cm.

ROTOVERT –  ROTOVERT TILT – TILT INTERFILARE – MINITRACTOR EL FURBO

dischi colibrì

The Colibrì motorized disc pack weeds actively, working at a depth of 2 cm. The height is
adjusted via a hydraulic piston controlled electrically via a linear potentiometer to determine
the actual working depth.
Weeding with COLIBRÌ allows for work in several rows at once starting from 5 cm, with a
coverage of 80% of the surface tilled by the COLIBRÌ disc, equal to 60% of the surface
of the entire bed.
The COLIBRÌ weeding machine used on fourth-range crops increases and improves
production:
1. The seedlings sprout earlier so they can be harvested earlier than non-tilled crops.
2. For rocket, a further benefit – aeration – is seen after the first pass.
A unique characteristic on the market, there are two types of COLIBRÌ disc teeth:
Teeth are straight (Fig. 1) or angled opposite to the plants, protecting the plant by pushing
the soil outwards. Suitable for narrow inter-row distances of 4.5 cm, or when the plant is in
the first stages of growth and therefore very delicate.
Curved sawtooth teeth (Fig. 2) arranged in the spaces not occupied by the seedlings remove
weeds and increase the working range of the weeding action.
The discs have a diameter of 320 mm, while the teeth are 40 mm in height and work at an
adjustable depth equal to or less than 30 mm, to preserve the leaf collar of the plant.
Both the speed and configuration of the discs can be adjusted based on the stage of plant
growth and soil type.

COLIBRì – MINITRACTOR EL FURBO – ROTOVERT

rotofilm

The Rotofilm rotors have been covered with rubber tubing to work on the
plastic film near the bed without damaging it. The rounded shape of the rotor
and rubber coating prevent the film from tearing and curling, both at the
beginning of the season when it has just been laid, or later when it has
deteriorated and is more delicate. It can also be applied to biodegradable film,
which is more delicate and prone to breakage.
The rotors work closer to the sheet than any other weeding machines on the
market.
Weeds are removed via the mechanical action of the rotor, and the soil is then
turned onto plastic film with a ridger or furrower.

ROTOFILM

rotoclean

Rotoclean discs are designed to loosen and work the soil to a depth of about 2 cm from the side of the mound and turn it over, dropping any weeds and stopping their germination. When in contact with the soil, the special star-shaped disc with 20 radial points allows the tiller to move forward easily. Given the convexity (to the right or left depending on the position on the ridge) with an angle of 20°, it turns over weeds growing on the side, allowing the soil to fall and drying out the weeds.

rotodisk

Rotodisk discs are designed to loosen the soil and turn it towards the upper part of the ridge. When in contact with the ground, the special curved 15-point star shape allows the tiller to move forward easily. Given the convexity (to the right or left depending on the position on the mound) with an angle of 15°, the soil is lifted as with a simple convex disc, with the difference that the soil is not retained and thus compacted at the sides, but is released, mixing along the side and removing any weeds that may have formed.
