Discover the BUSA™ Row Crop Cultivators!
Our Rotary cultivators redefine row cultivation for crops. The spaces between rows can be worked quickly and efficiently. Smaller safety distances, higher speeds, continuous, clog-free operation, wear-resistant, and reliable tools.
Suitable for compacted soil. Ideal for large farms. And organic farming. No-till, min-till and strip-till.
Advantages of the BUSA™ Row Crop Cultivators
Close safety distance of 4-7 cm
Due to the operating principle of the BUSA™ Rotor, it always rotates away from the plant. Thus, with certain adjustments, it avoids moving the soil towards…
the plant row, which allows even small plants to be cultivated with very narrow safety distances. While this is crucial for organic farms, elsewhere it’s simply a significant advantage.
King of weed control
Unlike other cultivation tools, the BUSA™ Rotor doesn’t merely make a single cut on the weeds found between rows. With its closely spaced blades…
it crushes them, cuts them during rotation, uproots them, and then presses them below the surface. In certain settings, it can even make shallow ridges, suppressing weeds emerging within the rows While chemical-resistant weeds exist, we’re yet to discover steel-resistant ones.
Clogging-free operation
The BUSA™ Rotor is highly resistant to clogging. Incoming plant residues actually force the rotating blades to spin more vigorously keeping them self-cleaning.
It not only handles well-established weeds between rows and surface residues during mulching but also rescues overgrown no-till areas without any issues.
High operational efficiency
Even at high speeds, the BUSA™ Rotors do not damage the row structure, resulting in exceptional field performance. The forged blades of the BUSA™ Rotor are…
durable even in compacted soils (6 rows – 1000 … 2000 hectares). The rotors require minimal maintenance and can operate nonstop. Where other cultivators struggle to clear accumulated weeds from their blades, the BUSA™ Rotor glides effortlessly.
Frame variations
From single-row cultivators to 12-row giants, there are numerous machine variations available. You can order a simple but reliable manually foldable frame or even a hydraulically…
collapsible 12-row version that spans up to 2.5 meters in width. Precisely delivering solid or liquid fertilizers into the soil is also a non-issue.
Row guidance camera
We take pride in designing one of the most precise frame structures using the Claas Culti Cam camera-based row guidance system.
The BUSA™ camera system doesn’t move the tractor around; it keeps the machine on track. Tirelessly. Reliably.
History of the product family
What exactly is a KS?
Interrow cultivation has so far been one of the most time- and energy-consuming jobs, because you either maneuvered slowly between the rows so as not to cut the plants, or you only cultivated the middle of the row with a large protective distance in order to move forward. However, it is truly important to perform weed control and eliminate soil compaction right next to the plants.
We have long known what the BUSA™ Seedbed maker is capable of, but we only started using its smaller version at the end of the 2000s. We had no idea what a powerful tool we had created. Initially, it became a favourite on organic farms due to its efficiency, and later, its high performance made it popular in large-scale operations.
The BUSA™ Rotor has already proven itself in the highly critical markets of Western Europe as well. It has few competitors when it comes to interrow cultivation. Closer, faster, and more thorough. The realization in the 2020s is that the BUSA™ Rotor could be the solution for chemical-free no-till farming.
Why is it worth using the BUSA™ machines?
The Rotary row crop cultivator allows you to efficiently cultivate your row crop from plant emergence up to nearly 1 meter in height These cultivators work with precise safety distances of approximately 3-6 cm between rows. The compact, forward-positioned cultivation elements on the robust frame (positioned as close as possible to the power unit) enhance accuracy (reducing overlap) and significantly reduce transport size. The dead play of the swing arms can be adjusted to maintain precision.
By using the BUSA™ Rotor attachment, you can further enhance accuracy. When the rotor is momentarily stationary, the blade moves downward next to the plant, then starts moving toward the center of the row. This design ensures that even at high speeds, the plant is not thrown out along with the soil, and row disturbance is minimized. As a result, even very small and delicate plants can be effectively cultivated. Our product range also includes other cultivator attachments such as duckfoot tines, angle tines, heaping tines, and s-tines.
Reducing chemical usage
Plants tolerate chemicals, but they don’t necessarily like them. Herbicides are becoming more expensive and less effective. If we can perform cultivation at a pace comparable to chemical application, efficiency becomes the key. For instance, if we cultivate a 37 cm wide strip (with an 18 cm safety margin), only half of the area needs chemical treatment.
By reducing the safety margin to 6 cm, we can significantly cut herbicide costs. This reduction in herbicide shock increases the chances of better crop yield.
Mandatory in organic farming
The BUSA™ Rotor’s thorough weed control, efficiency, and speed make it indispensable for organic farming. It has proven its worth on large areas using organic technology, often saving seemingly irrecoverable, knee-high weed-infested crops with our demonstration machines.
High operational efficiency
The BUSA™ Rotor’s speed and reliability allow for large-scale cultivation with fewer machines and operators. A 6-8 row BUSA™ Row crop cultivator is perfect for a 400-500 hectare farm. We know of several farms where the cultivators run nonstop day and night during the season, year after year.
What exactly is the BUSA™ Rotor?
The BUSA™ Rotor is a seedbed maker and primary tillage finisher based on a completely novel concept. It was developed and patented by our founder Benedek Horváth in the beginning of the 80’s.
The BUSA™ Rotor is used on the fields, in between rows and on plantations. It has strong clot breaking and weeding capabilities, thanks to its high speed and acceleration.
A huge advantage of our Rotor compared to rigid tools is that is does not get clogged and does not throw the soil about, which make fast work without constant supervision possible.
What kind of configurations are available?
Everything you need to know about the components
Gen3 Cultivator unit
Lightweight and versatile elements that can be equipped with various cultivator tools, allowing a single machine to perform multiple functions. The dead play of its parallel arms can be adjusted to zero after thousands of hectares of use.
Gen4 Cultivator unit
A specialized, reinforced cultivator element originally developed for the BUSA Rotor, designed to withstand the harshest, hard, dry soils.
This element can handle the extra load of disc liquid injectors mounted on the cultivating element. It is also used when attaching the K.U.L.T. Finger weeder to the cultivating element. The duplicated compression spring ensures that the additional attachments do not reduce the main tool’s load.
BUSA Rotor
A huge advantage of our Rotor compared to rigid tools is that is does not get clogged and does not throw the soil about, which make fast work without constant supervision possible.
Ideal for satellite-guided systems due to its non-clogging operation. The working depth increases as it moves away from the row, making it suitable even for small plants without a protective disc.
Its non-clogging operation allows cultivation in areas where traditional or spring-tine cultivating elements would struggle.
Angle tine
The standard configuration on cultivator units includes two asymmetric tines at the front and one duckfoot tine at the rear. This arrangement allows for a small protective distance because the elements working close to the plants are closest to the tractor’s pivot point, resulting in minimal crop damage.
Heaping tine
We offer two types of heaping hoes for our cultivators: a smaller symmetrical one and a larger asymmetrical hoe.
Both tools allow covering weeds in the inter-row space while supporting the crop. Additionally, they cover the fertilizer dispensed on the row, improving its utilization.
Vecsés tine
Our Vecsés tine kit is used for more robust cultivation and breaking up the inter-row space. It’s effective for weed control and has limited ridging capacity.
Spring-tine
Responding to demand, we also offer spring-tine cultivating elements for our cultivators. These perform more aggressive loosening in the inter-row while being less prone to clogging compared to traditional rigid elements.
Granulated fertilizer
Our Row crop cultivators can be equipped with stainless steel dispenser tanks containing drill units. The drive can be…
mechanical belt-driven, electric motor-driven, or equipped with an electric motor with road-based GPS control. The dispensers can be fitted with precision controller units, making them a precision tool.
Liquid fertilizer
We offer a wide range of options for liquid application. Typically, we use Polyfarm 1100 or 660-liter tanks. For rear-mounted implements, one or two tanks can be attached…
and for front-mounted implements, one or two tanks can be fitted. For more advanced systems, we use AnnoviReverberi diaphragm pumps, Arag proportional valve systems, and Farmscan Jackal GPS-based rate controllers. We recommend applying liquid fertilizer at a depth of 6-10 cm into the soil using injectors. For uniform and flexible application, we use the TeeJet QJ-VR nozzle series.
Small seeder
For row crop greening and sowing cover crops, our cultivators can be equipped with a small-seed sowing adapter. While it is risky to use in Hungary’s climate, in areas…
with more precipitation or irrigation, you can sow legumes or grasses between the rows after the final cultivation. These intermediate crops germinate but are suppressed by the main crop during growth. After harvest, they can thrive immediately, ensuring root continuity and soil cover.
Protective disc
A protective disc can also be installed on request for our Rotary and Spring-tine elements.
Finger weeder
For keeping spaces between plants weed free. Available in various mountings and sizes. Original K.U.L.T. Finger weeder. With several sizes and different settings.

Frame structure categories
Classic fixed
Simple but effective, it is typically used for smaller machines with fewer rows. Since we use the same cultivator elements as with larger machines, the beam size becomes comically oversized.
The advantage of the fixed frame is that we can place the cultivator element wherever we want, making it a good solution for special crops. For example, in tomato cultivation, when dealing with small plants, two elements are placed in one row, and as the plants grow, we only need to attach the element to the middle of the row.
Manually foldable
Our patented vertically articulated hinge mechanism is simple, easy to operate, and durable. If you want to use a fertilizer dispenser, it’s practical that the folding motion is not upward.
Otherwise, you’d have to choose between pushing the tank backward (limiting lifting capacity) or pushing the cultivator backward (severely compromising precision).
Hydraulically foldable
Our hydraulically foldable frames fold to a transport width of 2.5 meters. The diagonally folding frame creates space for a small tank.
The vertically folding frame can be attached both forward and backward. Our 12-row frame folds itself twice into a 2.5-meter wide, 4-meter high road clearance.
Front-mounted
The advantage of a front-mounted cultivator is that it provides visibility for the operator. It moves in the direction the tractor’s steering wheel turns, balances the inherently…
rear-heavy tractor on slopes more easily without the risk of drifting while correcting. It’s important that the frame floats without guide wheels, as guide wheels would make the tractor uncontrollable.

Frequently asked questions
Forged tools have high wear resistance and strength. While many farms encounter this issue, the BUSA™ Rotor handles it without any trouble.
After the first use, the paint is wearing off from the swing arms. The dead play of the swing arms can be easily adjusted to maintain precision, ensuring accuracy regardless of wear and tear on the machine.
Firstly, with this cultivator, you can get into the rows much earlier. Our organic farmers are already using it among very small plants, preventing weeds from gaining strength. Even if they don’t get there in time and the weeds take over, this tool still performs well. It doesn’t clog even in dense grass or heavy weed infestations.
Similarly to conventional field machinery, the angle of the Rotors can be adjusted here as well. While a larger angle may be necessary for heavy weed infestations, it’s essential to tailor the machine settings to the current soil conditions.
When dealing with compacted soils, it’s advisable to operate the BUSA™ Row-crop cultivator at a steeper angle. This makes its work more aggressive. Additionally, the spring deflection can be adjusted independently for each element, allowing you to force the cultivating elements into the soil on hard terrain. The spring load can be adjusted easily and steplessly, ranging from 0 to 80 kg of downward force. It’s equally suitable for tilling loose and dry as well as compacted soils.
Our cultivator units can be equipped with various tools through minimal part replacements. For instance, a s-tine cultivator can be converted for heaping tine, or later equipped with a BUSA™ Rotor.
Our Gen4 cultivating elements, equipped with BUSA™ Rotors, can be fitted with disc injectors on our machines. This allows for simultaneous cultivation and injection using a single piece of equipment. Additionally, surface application of liquid can also be achieved. For uniform and flexible application, we use the TeeJet QJ-VR nozzle series.
For row crop greening and sowing cover crops, our cultivators can be equipped with a small-seed sowing adapter.
For hilly terrains, we recommend our front-mounted cultivators. These machines effectively balance the inherently rear-heavy tractor on slopes, making it much easier to handle without the risk of drifting while correcting.
Our cultivators can be equipped with Claas-developed, world-leading camera-guidance systems. Supported by cameras, our rotary hoe machines can work with exceptional precision (with a protective distance of 4-4 cm) in three shifts throughout the entire season, requiring minimal maintenance and supervision.
