Optima TFprofi

For mulch and conventional sowing

• Optimal depth control even under extreme conditions, 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 the spring-loaded system.
• Effective ground contour following, due to the large lateral depth control by open gauge wheels (Ø410mm, width 120mm).
• Precise seed placement by the small coulter which forms a clean furrow. Light re-compaction and seed covering is done by the intermediate press wheel (as option: heavy stainless steel) and the multi-adjustable V-press wheel – to ensure maximum field emergence.

Seeding heart without seals for HD-II

• The patented seeding heart by Kverneland has reduced maintenance costs to a minimum.
• No friction, no wear, low drive torque, minimum maintenance: The seed disc rotates in the seeding heart together with the vacuum chamber. This seeding drum is connected to the vacuum fan via a hollow shaft.
• This seed heart principal results in no loss of vacuum, and therefore a low vacuum requirement

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.

The new fertiliser hopper has a capacity of 2,000l. The wide opening of nearly 3m enables the filling with front loader or big bags. An optional filling auger is also available.

The dosing units can, as an option, be driven electro-hydraulically. This is controlled and monitored via ISOBUS. The electro-hydraulic drive of the metering device enables constant adaptation of the application rate during work (as well as via application charts with GEOCONTROL). In addition the exact switching on/off at headlands is also possible. 

The fertiliser dosing is done by two quad outlet dosing units. Each row comes with its own air support to ensure the steady conveyance of high amounts of fertiliser especially when working on hillsides.

Another option is that the fertiliser hopper can be placed on 4 weigh cells for a constant control and monitoring of the application rate. Prior to operation, the amount of fertiliser required for the job can be filled into the hopper and can be adjusted to what is really needed.

For contractors whose machines work for several customers, a further advantage is the possibility to invoice the fertiliser used accurately to the kilogram.

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 offered in two different levels:

GEOSEED Level 1 is the synchronization in the machines working width. This improves the distribution of seeds up to perfection in parallel or diamond pattern: Positive effects are the best use of nutrients, water and sun. Also the wind and water erosion is decreased.

GEOSEED Level 2 is the synchronization in the whole field. This is the necessary requirement for interrow cultivation, also across the seeding direction. GEOSEED is the only system in the world, that makes this mechanic weeds control possible!

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.
