The CHOPSTAR-TWIN precision hoe was developed for precise hoeing above the row. The hoeing parallelogram does not work between the rows, but is mounted directly above the row. This allows a very narrow hoeing belt, which makes it possible to hoe young crops very early and narrow at the same time.
This is achieved by two cutting disc adjustable in angle in combination with following angle knives: two Farmflex wheels running close to the crop row ensure an exact working depth of the hoeing elements. The CHOPSTAR-TWIN, in combination with the camera steering system ROW-GUARD, is perfectly suited as a precision hoe for special crops, cereals, soybeans, beets, corn, vegetables, herbs, etc.

Concept of row-crop cultivators
The concept of the CHOPSTAR row hoes is its variability and the many possibilities of individual tools for various crops. The same strong and solid frame is used for all row hoes. Almost any row hoe can also be equipped with the automatic camera steering system ROW-GUARD.
The wide parallelogramms 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 parallelogramms provide enough space to compensate unevenness of the fields on each element, on hills or pans. The retraction support, which you can adjust in three steps guarantees a better penetration of the hoeing tools, also in hard crusted soils. This allows to work with increased working speed without vibration or jumping of the elements.

Twin-hoeing element with vertical cutting discs and angle knives
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 30 cm / 11.80" up to 75 cm / 29.50".

Weed control over the full surface
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.

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

Continuously variable adjustment of the working depth
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 parallelogramm should be adjusted individually, because e.g. the tracks behind the tractor wheels should be hoed deeper in order to break them up.

High retraction support of hoeing elements
All Einböck row-crop cultivator parallelograms are fitted with three-step adjustable retraction spring as standard. This allows a penetration pressure of up to 105 kg / 231 lbs on each hoeing element (depending on the equipment, working position and spring preload). These adjustable springs ensure a smooth running of the hoeing elements even at high working speeds and safe penetration even into hard and crusted soils.

Design of the finger weeders
The finger weeders, which are available as additional option, are used to break up the unworked hoeing belt (area very close to and between the crop plants) and to control weeds in early growth stage. The two stars of the fingerweeder are placed parallel on both sides of the row and they are mounted on a separate, spring loaded holder. This ensures excellent adaption to the soil and perfect guidance of the fingerweeder - without damaging the crop and especially the roots.

Technical data and specifications are approximate and without obligation. Construction and design are subject to change.
Strong frame for high loads Rigid or hydraulically folding machines have a strong frame, on which the parallelograms are mounted. The special Einböck-profile-frame allows a fast and simple assembly of the parallelograms. Because of the special frame-form the frame can stand a very high number of hoeing seasons without any problems. Furthermore, the row spacing can be adjusted quickly and infinitely variable.

Upper link steering An automatic upper link steering system is mounted as standard on rear-mounted hoeing machines. This ensures precise hoeing even on hilly conditions and curves. Hoeing on hills with an incline of up to 6 % is possible. Even in curves, the row-crop cultivator runs as close as possible behind the tractor track. Steering is done via gauge wheels. The implement does not need to be carried by the tractor. It is therefore used with position control and swinging lower links (approx. 7 cm / 2.80" each side). With the CHOPSTAR-TWIN, a ROW-GUARD sideshift frame with camera steering or hydraulic steering control is recommended so that the narrowest possible hoeing band can be achieved.

Bolted or clamped mounting of the working tools All working tools are bolted or clamped to the frame. This has the following advantages for the user:
Always a tight fit (no getting lose) of the working tools, especially during working on the field
Set distances or working depth are precisely maintained
No deflection of the connections and minimal wear and tear
Durable fixings/clamps withstand many hoeing seasons
Fixing of the tools without clearance what results e.g. in exact guidance of the sweeps
Allows very precise, infinitely variable adjustment

Monitoring camera for row-crop cultivator
The monitoring camera with a special lens for a narrow field of vision is designed for row-crop cultivators. It ensures convenient observation and control of the operation and the hoeing belt via a monitor in the tractor cab. The camera is mounted with a holder on the frame of the hoe.

Further tailor-made solutions For our hoes there are a lot of additional options available. Depending on row distance or other options they might not be available or could not be combined with each other. In addition, there are more options available which are not mentioned here. When you let us know details of your request, we can check the possibility to fulfil your request. To be able to do so, we always need a filled in CHOPSTAR-CHECKLIST.
Manual hydraulic steering 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. The hydraulic steering is not or only partially usable on machines with finger weeders and hydraulic lifting of the parallelograms.
