Rotative row-crop cultivator ROLLSTAR

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.

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.

To ensure aggressive hoeing as well as intensive hilling, the row cultivator can be equipped with ROLLSTAR-hoeing sections. It is developed for hoeing of hill crops, but it also can be used for field crops, if the row distance is wider than 45 cm / 18″. Optional protection shields are responsible to protect the plants from spilling (especially in early crop stage). To break up the soil and to guarantee the stars can enter the soil easily, there are S-tines at the corn-version and vibro-tines at the potato-version of the ROLLSTAR element. Depending on the crop there are different setups of the hoeing-elements available:

1. Field crops: corn, sunflowers, beets, soybeans, …
2. Hill crops: potato, carrot, leek,…

Because of the perfect choice of the material, the hoeing stars are extremely wear-resistant and they can stand many years of operation. Each hoe star is equipped with an angular roller bearing (this increases the stability) and it is adjustable and individually removable.

• 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.

To hydraulic lifting SECTION-CONTROL

Rear-mounted row-crop cultivators come standard with an automatic upper link steering system. This ensures exact hoeing, also on hills and bends. The row-crop cultivator is guided exactly behind the tractor, even if there are a lot of bends. The cultivator is steered via the upper link of the 3-point hitch by metal gauge-wheels, therefore the machine is used with position control on the 3-point linkage.

The gauge wheels ensure perfect guidance of the hoe and stability at hilly conditions. The tractor’s front wheels are not relieved of load, as the weight of the machine is carried by the gauge wheels. Especially on hilly conditions, the gauge wheels help prevent the implement from drifting. Scrapers ensure that the gauge wheels do not become clogged.

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 in order 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.

To loosen the soil in front of the roll-stars, pre-loosening tines are mounted.

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.

To protect small plants crop deflector shields can be mounted.

For large farms and machine communities even more solid “HUB”-bearings are on offer.

For hill cultivation, a hill weeder with a parallelogram and a comb weeder can be mounted to pull out and bury weeds on the hill.

When the ROLLSTAR is used front mounted, a special front mounting support is needed.

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.

For professional and precise work of the jockey wheel even on light soils, pneumatic wheels (instead of the standard Farmflex jockey wheels) are available as an option. These ensure that the desired working depth is maintained in very light or sandy soils thanks to a wider tread.

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.
