Precision row-crop cultivator CHOPSTAR-TWIN

In order to enable the cutting discs and angle knives of the “TWIN” hoeing section to be adapted to different crops quickly, they come as a standard feature with the SMART-GRIP quick adjustment system. This saves time by quickly adapting the row-crop cultivator to a wide range of conditions while maintaining the best possible grip – thanks to a special quadruple clamping. The angle knives can be rigid or spring mounted.

The earlier and the closer to the row hoeing can take place, the easier the weed control in the row can be done (e.g. by finger weeders or rotative weeder elements). This ensures reduced weed pressure and supports a good establishment of the crop.

The wide parallelograms are equipped with retraction support and durable Farmflex feeler wheels. Furthermore, they can be adjusted in the joints, this guarantees a high (side)stability and accuracy after many years of use. The long parallelograms provide enough space to compensate unevenness of the fields on each element, on hills or pans.

All Einböck row-crop cultivator parallelograms are fitted with three-step adjustable retraction spring as standard. These ensure that the hoeing tools penetrate better, even in heavily crusted soils, and enable higher working speeds without the elements vibrating or jumping.

The cutting discs in front of the angle knives allow to operate the machine in mulch or no-till, but also strip-till crops. The organic matter is cut close to the plant row what brings precise and quick hoeing without clogging.

The finger weeders are equipped with an additional parallelogram to enable a perfect ground adaptation. In addition, the aggressivity of the finger weeders could be adjusted by a spring. Each pair of finger weeder stars could be set up quickly to the field condition by the ”SMART-GRIP”- quick adjustment mechanism.

• Sideshift frame and row-crop cultivator are mounted very closely together
• One sideshift frame can be used for several row-crop cultivators
• Latest version of hard- and software
• Precise row recognition in different row-crops
• Best visibility – even in fields with heavy weed infestation and/or small crops
• Proven a thousand times

Many sophisticated additional options such as following working tools, SECTION-CONTROL element lifting, camera steering, etc. make every Einböck row-crop cultivator an individually adaptable machine. So, every cultivator is designed to perfectly meet current conditions, crops or types of soil.

The hoeing section is guided by two Farmflex-support wheels left and right of the row. It is equipped with two vertical cutting discs, which are followed by two angle knives. They are mounted on vibro-springs, so it is possible to work very closely and shallow to the crop. The result is that young crops can be hoed earlier, closer to the crop and with higher working speed than with standard row-crop cultivators without burying plants. In ideal conditions a hoeing band of less than 5 cm / 1.90″ can be realized. The CHOPSTAR-TWIN can be configured from 35 cm / 14″ up to 80 cm / 31″.

The stable machine frame, to which the hoeing parallelograms are attached, is available in a rigid version or with a hydraulically foldable design up to a width of 19 m / 62 ft. The special Einböck profiled tube allows for quick and easy mounting of the hoeing elements. The special frame shape and design ensures maximum durability and an exact fit. In addition, different row distances can be quickly and infinitely adjusted. The ROW-GUARD camera steering system can be mounted on all frames as well.

1. Rear frame for rigid machines with upper link steering
2. Frame folded hydraulically (rear with upper link steering)
3. Rear double folding frame up to 12 m / 40 ft
4. Rear double folding frame and wide middle frame up to 19 m / 62 ft
5. Special frame

Depending on the configuration, different tines and sweeps can be mounted:

• Einböck special vibro-tines
• Standard vibro-tines
• Einböck-special-ultraflat
• S-tines
• Carbide metal sweeps
• Heaping sweeps & angle knives

The working depth of the hoeing section is continuously variable adjustable with a spindle on the depth control wheel. So, the working depth of the hoeing tool can be adjusted to the millimetre and it is perfectly maintained during operation. A scale shows the actual adjustment. Each parallelogram should be adjusted individually, because e.g. the tracks behind the tractor wheels should be hoed deeper to break them up.

A frame clearance up to 70 cm / 28″ makes working in bigger crops like corn, sunflowers, etc. possible. So efficient and careful hoeing / ridging up in late growth stage does not cause any problem.

The section has a lifting height of up to 35 cm / 14″ (depending on the machine configuration and soil conditions) and can automatically be controlled by GPS via SECTION-CONTROL, or manually by switches. Lifting the sections ensures no crop is damaged at the headlands when the fields are not square. This option is especially recommended for contractors or farms with a lot of misshaped fields.

The finger weeders (also called finger hoes) or the rotative weeder elements pull out or spill weeds between the plants. In this way, the unworked hoeing area is worked and thus the crop is additionally “cleaned”.

A ROW-GUARD camera-guided sideshift frame can be mounted to each row-crop cultivator, also retro-fitted.

For hoeing the unworked space between the TWIN elements, up to two additional tines can be mounted.

The pneumatic seeding box P-BOX or the front tank JUMBO-SEED can be optionally combined with the row-crop cultivator. These can be used to apply under-seeds or fertilizers during hoeing.

The JUMBO-STREAM front tank for liquids offers efficient solutions for combined weed control. In combination with the proven CHOPSTAR-PRIME row-crop cultivator, the front tank enables effective mechanical weed control that includes hoeing and simultaneous band spraying or fertilizing.

In order to increase the precision of a row-crop cultivator without camera steering or to reduce the width of the hoeing belt, a manual hydraulic steering is optionally available. This accessory allows a person to steer the row-crop cultivator independently from the tractor. The seat is positioned so that the best view on the crop row is guaranteed. The steering is hydraulically operated, so that even longer hoeing operations can be done.

Our hoeing technology offers numerous additional options and special equipment. In addition, there are many other individual solutions that we have successfully implemented following customer requests over the last 45 years. To optimally adapt your row-crop cultivator to your requirements, we need as much detailed information as possible. Our CHECKLIST is a helpful tool for this purpose.
