Kverneland Onyx 4000 F

The Kverneland inter-row cultivator, ONYX with the Double-H shaped frame offers a maximum in rigidity and adaptability. Ready to be upgraded by extensions, the frame is quickly prepared for larger fields and farms.

Double-H frame

The Double-H shaped beam offers a maximal sturdiness and allows a firm fixation of the weeding elements. In addition, it increases the penetration force by transferring the load to the tines and shares. Its sturdy concept provides safe transport on roads. The ONYX is equipped with the standard version of Cat. II linkage. The spacing between the elements can be simple changed due to the universal frame system (UF System). Hydraulic and electrical interfaces are simple to connect with the push pull system and are easily accessible.

Three models

The product group of the Kverneland ONYX proposes three models, mounted and foldable: standard, compact and integrated according to their type of linkages. Each frame can be upgraded with frame extensions with different tube lengths of twice 120, 800 or 1450mm to obtain a width on the compact folding version of up to 7.70m and the wide folding version of up to 12.10m.

Pneumatic gauge wheel

Either two or four additional gauge wheels positioned in front of the middle frame bar or/and at the outer extensions ensure an optimal following of the ground contour, give more stability and a constant depth control especially with larger working widths. Depth setting is done mechanically via a clamp lockable crank on all wheels. A scale indicates the depth for precise adjustment.

Parking legs

Original parking legs are delivered as standard for storage of the machine. The parking legs allow an easy and safe coupling and uncoupling to the tractor.

The Kverneland Onyx can be equipped with different tines and shares to meet all requirements and conditions. The aim is to protect the plant while suffocate and scalping the weeds as closely to the crops as possible, maintaining soil moisture by shallow tillage and moving the soil as less as necessary.

The height adjustable straight A-tine without vibration effect with either A-shaped flatbed weeding or L-shape lateral adjustable shares ensure shallow tillage with precise scalping of the weed and can be used in all crops. The L-shares which are available in left and right version limits soil projections on young crops and are mounted on tines positioned close to the seeding row. Several share widths and assembly options are available for row widths from 12.5 to 80cm.

Alternatively a semi-curved SC-tine with duck foot share (DF-share) or half duck foot share (HDF-share) allow deeper and more intensive soil tillage due to a higher vibrating effect. Optionally a ridger share positioned on the tine which is the closest to the sowing row of the crop and guides the soil flow directly to the sowing line. It is particularly suitable for developed higher crop vegetation to avoid suffocation of crop but not of the weed in the line.

The Kverneland Onyx features high quality with long lasting components. Thus, the Onyx inter-row cultivator maintains its reliable and accurate  performance even under most demanding conditions.

X-CONTROL parallelogram

The parallelograms are equipped with conical pins and hardened polymer bushings which do not float and rule out any wear and play. This provides excellent stability and high accuracy from 12.5cm up to 80cm row width. The constant depth control over the entire working width ensures best results in row crops and cereals. A hydraulic or mechanical parallelogram version is available. They are adjustable in both depth and pressure.

Both versions are equipped with a preloaded double springs system, the exclusive X-CONTROL. This pre-loaded, spring-based system provides an individual load transfer from the frame to the tines of max. 120kg and eliminates any play or bouncing of the element. This gives the tines extra stability. The working depth stays absolutely constant, which is essential for the effectiveness of flatbed weeding at shallow depths without mixing the horizons.

Mechanical weeding with GPS-GEOCONTROL function in combination with an ISOBUS compatible mechanical inter-row cultivator ONYX is a major step towards precision farming and cost savings. Each weeding element with hydraulic control is automatically lifted or lowered due to the Automatic Lifting System in exactly the right place. The one-to-one hydraulic adjustment of the parallelograms is steered from the terminal, weeding element by weeding element via GPS shut-off.

The aim is to best preserve the growing plants which can be especially challenging in triangular fields, on curved or odd-shaped headlands. You can also continue weeding at night since the GPS-GEOCONTROL switch on/off is precise and reliable.

When equipped with ISOBUS technology, the Inter-row cultivator Onyx is fully configurable and automated via the IsoMatch Tellus PRO terminal. It will relieve the driver’s stress. By automatically dodging some predefined areas providing a true precision operation, even with poor visibility or high vegetation.

IsoMatch Tellus PRO – increasing productivity

The IsoMatch Tellus PRO 12-inch terminal provides you with the optimal solution for an all-in-one control system inside the tractor cab. It is the centre for connecting all ISOBUS machines, running precision farming applications and Farm Management Systems.

It offers everything you need to get the maximum out of your machines and crop, as well as cost savings in fertiliser, chemicals and seeds by using automatic section control and variable rate control. With the unique dual screen functionality it gives you the opportunity to view and manage two machines and/or processes simultaneously.

Easy control management

The IsoMatch Tellus GO+ is a costefficient 7-inch terminal, especially developed for managing the machine in a simple way. Easily set up the machine with the soft keys and simply use the hard keys and rotary switch for optimal control while driving.

Kverneland always focuses on safe operation and user comfort. With all the adjustments being done without the need of special tools, a lot of precious time is saved! Adjusting the Kverneland ONYX is easily done with only one spanner (22mm). A wide range of configuration possibilities are available to meet all kind of requirements and conditions and to achieve best results.

1. With the hydraulic linkage of the tractor the implement is adjusted horizontally aligned with the complete frame.

2. The working depth is set-up by the gauge wheels of each element. The pressure adjustment at the parallelogram is regulated via a pre-loaded spring which transfers the weight to the tines and shares. Scales indicates the exact adjustment.

3. For the precise row width each tine can be adjusted to the side with sliding elements.

4. Finally, each additional accessory e.g. finger weeder, side plates, finger harrow, discs etc. or the feeler and camera must be fine-tuned to the field conditions and growth level.

5. The spring protection of the weeding element supports the penetration and ensures a constant working depth
