Optima F

Up to 18km/h for utmost efficiency

• Optimum depth control due to the heavy basic weight of the sowing unit with the possibility to add additional pressure (up to 100kg) onto each individual sowing unit via spring-loaded system.
• Effective ground contour following due to the large depth control by open gauge wheels (⌀410mm, with 120mm)
• Precise seed placement by the small coulter which forms a clean furrow. Good placement, and seed covering is done by the smooth flexible intermediate press wheel and multi-adjustable V-press wheel.

Seeding heart – Optima SX

• With the pressurized seeding heart, the seeds are “shot” by an airstream of up to 70kph into the furrow. A smooth, flexible intermediate press wheel catches and protects the delicate seeds. Any negative impact such as vibration on the way between release point and soil contact are eliminated due to the high air stream.
• The seeds reach their perfect position in the soil. Each sowing row is electrically powered by ISOBUS connection. An additional generator or other power sources are not required. The complete power supply and control is via ISOBUS.

e-drive II – complete control and monitoring of the machine from the tractor cab in accordance with ISOBUS standard

• With e-drive II, each sowing unit is driven individually via an electric motor.
• The low-maintenance drive is connected directly to the seeding heart via a toothed belt in an encapsulated dust proof housing.
• This enable an extremely compact design and smooth drive characteristics with low current consumption
• All the data is entered and read out via an ISOBUS terminal like IsoMatch Tellus PRO or Tellus GO+.
• The sowing distances are infinitely adjustable and can be changed during sowing.
• All the sowing units can be switched off individually.
• In conjunction with “close row” sowing widths of 37.5cm a further benefit of the e-drive II comes into play: Individual tramline switching. Tramlines can be set up for any spray width.
• The e-drive II features complete electronic monitoring of all machine functions including seed monitoring via an opto sensor.

Micro-drill for Optima HD-II and SX sowing units

The demand for microgranule applicators is increasing. Micro nutrients and also small amounts of insecticides or fungicides ensure the best start of the crop.

The electric driven micro-drills for the Optima HD-II and SX sowing units have been designed as backpack behind the sowing units and offer a hopper capacity of 17 liters.

They are electrically driven and ISOBUS controlled. The metering device consists of a wear-resistant plastic housing with exchangeable cell wheels made of stainless steel. This ensures the precise metering of the micro granules.

Operator’s safety

The engineers had focus on highest level of operator’s safety by offering easy and safe handling of the applicator. Therefore, the operator can exchange the cell wheels even when the hoppers are full of micro granule. There is no need to empty them first, reducing the operator’s risk of getting in direct contact with the granules.

A plus for the environment

The micro granules fall freely into the seed furrow without any air support, minimising the emission of dust. Therefore, the new micro-drill fully complies with the current guidelines for emission control of any granules applied.

Precision Farming

The comfortable, fully ISOBUS integrated control system allows the adaption to the stop and starting points of the seed row. This ensures precise shutting on and off at the end of the field and in tramlines (without overlaps or faults).

IsoMatch GEOCONTROL - Cost saving with immediate payback 

Seeding with GPS and GEOCONTROL in combination with an electric driven precision drill is a major step towards precision and cost saving. These machines are all equipped with ISOBUS technology which with the help of the IsoMatch Tellus terminal, can be easily controlled. 

Each electric driven seeding element, in combination with GPS and GEOCONTROL, is automatically switched on or off in exactly the right place, ensuring there is no overlap with any row that has already been seeded. This is especially handy in triangular fields, on curved or irregular shaped headlands.

GEOSEED - Precision at high end

GEOSEED is the precise synchronization of seed placement across the full working width of the machine. This ensures that seeds are distributed evenly, achieving an optimal pattern—either parallel or diamond-shaped—across the soil surface. The positive effects of this technology are far-reaching. By enhancing seed distribution, GEOSEED maximizes the efficient use of key resources such as nutrients, water, and sunlight, fostering optimal plant growth. Additionally, this uniform planting pattern helps reduce the risks of wind and water erosion, as the even distribution of plants improves soil structure and coverage, leading to better water retention and minimizing soil degradation.

Due to varying soil conditions and working speeds, the force required to maintain a defined working depth will vary. Kverneland GEOFORCE is the automatically steered constant depth guidance on the go, independent from changing soil conditions, residues, weather and working speed. Perfectly precise seed placement at an even sowing depth is the pre-requisite for optimal field emergence, good harvest conditions, resulting in higher yields and best corn quality.

With the new GEOFORCE system, each individual Optima sowing row is automatically pressurized adjusting to changing soil conditions or forward speeds. The automatic, constant pressure control ensures optimal seed placement at an even seed horizon which results in uniform seed germination and field emergence. Especially smaller seeds like rape, which need a shallower sowing depth, benefit from the release option of GEOFORCE. In addition, the bulldozing effect or formation of dams in very light soil conditions are prevented.

The GEOFORCE system 

Varying conditions are challenging as light soil requires less pressure to penetrate the soil by the cutting discs than heavier soils. The weight of the sowing unit is either not enough or already too heavy. The target is to ensure even depth control for precise seed placement in various soil conditions and working speeds by maintaining a constant contact force with a consistent weight on the gauge wheel. Sensor technology converts this information and a double-acting hydraulic cylinder in the parallelogram adjusts the oil pressure to guide the sowing row to an even depth. Each sowing unit is individually monitored and automatically regulated on the go. With the GEOFORCE system, all rows keep up the same sowing depth, also those running in more compacted areas like tractor tracks.

Benefits, Comfort and Savings

The Kverneland GEOFORCE reduces operator's workload, monitors and improves the quality of sowing. GEOFORCE ensures an even seed placement and plant development. This will decrease farm production costs and lead to a higher, better-quality yield.

Uniform germination and an even field emergence promote quick soil coverage by leaves, reducing weed pressure. Less chemicals or mechanical weeding passes are required. The risk of losses due to bird damage attracted by uncovered seeds or missing emergence due to too deep seed placement is minimised. Smaller seeds at shallow sowing depth, like rape, benefit from the ability to release the row, making it independent of row weight. With pressure generated precisely where needed on the row, optimal seed placement is ensured. Kverneland GEOFORCE reduces fuel consumption by minimising bulldozing effects and enables smooth operation at higher working speeds. Moreover, the maintenance cycles and lifetime of the coulters and wearing parts is extended due to the adapted pressure adjustment on the go. 

The Kverneland PUDAMA system solution

Fertilisation ensures the supply of nutrients to the crop, but over-fertilisation often has undesirable effect on the environment and the ecosystem of the land.

How to keep the balance?

Conventional band application places a continuous band of fertiliser also between the plants, where the roots cannot reach it. This is the amount of fertiliser simply wasted and washed out.

Kverneland PUDAMA

With PUDAMA the amount and location of the fertiliser is precisely defined. The nutrients are only deposited where the roots of the grain can reach it and only as much as needed. Synchronised with the seed application at high speeds, a cloud of fertiliser is placed by an air stream below and sidewards to the seed during seeding process. Every seed has an optimal fertiliser depot at its disposal which is completely absorbed by the plants. In this way, loss and leaching is avoided and the production of fertiliser raw materials can also be reduced. In brief, PUDAMA is increasing the efficiency in the use of mineral starter fertiliser in maize – thus maintaining 100% yield whilst saving at least 25% starter fertiliser.
