Advantages of the BUSA™ Rotary Weeders

01
01

Energy efficiency

The company’s patented rotary hoe becomes the single most efficient tool of mechanical weed control because of its high working speed (~15 km/h) as well as its clogging-free operation.

Compared to disc harrows, the BUSA™ GYMF performs incredibly efficient weed control faster, while also requiring less energy for the same task.

Organic, pesticide-free weed control

The BUSA™ Rotor’s rotating blades are the most powerful weapons of weed control. Pesticide-resistans weeds do exist, but there are no steel-resistant ones. Because of its fast, easy and precise operation, you may work on a particular area mutliple times in the same season, which makes the machine a fail-safe weeding tool.

Cover crop control

The machine is also capable of controlling cover crops. For this purpose, the working depth is adjusted in a way that the machine does not rip the roots of cover crops, only lays them down and crushes them, thus disrupting their growth.

Smooth surface without earth embarkments

One of the big advantages of the BUSA™ Rotor is that it smooths the surface without moving much soil. The GYMF does not form ridges or furrows…

which makes it possible for the machine to move fast and without jolting even with a sprayer or trailer. This allows for a much faster completion of every possible task.

Minimal protective distance, maximum safety

With the BUSA™ Rotor, you may go as close as 5-10 cm to any particular row. If the trees are accidentally hit by the rotor’s blades, the blades roll on and…

the machine does not get stuck although the trees might suffer small injuries. This is not a problem when it happens occasionally, but generally it is to be avoided. We suggest the application of the K.U.L.T. finger weeder for weed control between plants, which protects tree trunks.

Durability

The forged Swedish steel blades of the BUSA™ Rotor are exceptionally wear-resistant. Their slim design hides a powerful and highly durable machine. It copes perfectly well with black soil and areas with a large number of pebbles. The Rotors are protected by coil springs designed for this purpose.

BUSA™ ROTARY WEEDER

History of the product family

What exactly is a GYMF?

GYMF is the product name for the rotary weeder using the patented BUSA™ Rotor. It is a special version of our seedbed maker also using the BUSA™ Rotor. Designing this simplified version was necessary because on plantations, fast and efficient cultivation could be achieved with only two lines of Rotors.

The concept of the machine is based on the following observations: The hanging branches of plantations call for a lower machine. The brutal force of the bigger Rotor is an unnecessary feature on plantations. From smaller Rotors we build machines with smaller increments, since machines of differing widths are required on different plantations. It soon turned out that a big advantage of the machine is that it allows cultivation very close to trunks and vine stocks. This is because the Rotor rotates away from them, so neither the plant nor the machine is seriously harmed by accidental collisions.

It is important to note, however, that collisions may result in small cuts on the trunks. For this reason, it is absolutely forbidden to collide with the plants intentionally and regularly, since this practice can ultimately destroy the whole plantation. In the last few years, various versions of the machine have been designed: three strip cultivator, front and back mounted versions, from small two-rotor machines to huge seven-metre-wide giants.

Why is it worth using the BUSA™ machines?

The rotary weeders using the patented BUSA™ Rotor have a huge economical advantage: time Time is of the essence, and this machine can perform the same task much, much faster than traditional machines, and with the same efficiency! A task which often takes a traditional machine days to complete, can be finished with a GYMF in as little time as a single afternoon. Another advantage is that it can work very close to the cash crops, even 6 cm-s from them, which reduces the size of the uncultivated strip. Furthermore, with the K.U.L.T. finger weeder mounted on the frame…

the spaces between plants can be kept clean as well.

Last but not least, if your plantation is cultivated using the BUSA™ Rotor, the machine’s surface smoothing capabilities will create a surface on which neither the sprayer bounces about, nor will the boxes jump off the trailer.

Surface

The simplest application of the machine is processing the whole surface of the row. In case of smaller row distances. this usually means one row being finished in one go, while for bigger row distances, the machine usually drives back and forth.

In a field where the row spacing is accurate to within +/- 5 cm, it is possible to achieve equally precise approach on both sides. Our product range features several different versions of the hitched rotary weeder, from a small fix-framed version with a 1.1 metre working width to a hydraulically folding giant with a 6 metre working width, and anything in between.

Orchard strip

The new tree strip cultivators usually process a 0.6 or a 1.1-metre-wide strip. There are simple fixed frame versions available, alongside machines with hydraulic telescopic extensions, which are capable of extending 2.8 metres measured from the centre line of the tractor.

The double-sided versions are capable of extending 2 metres measured from the centre line of the tractor. A pivoted frame ensures proper surface following. Mounting on the front can increase precision further.

Field

Alternatively, the GYMF can be used as field weeder, stubble conditioner, or seedbed maker. An interesting new application in min-till termination, where the BUSA™ Rotors are adjusted for ultra-shallow cultivation in order to make them the perfect tool for cover crop control.

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.

Frequently asked questions

How often do the machines get clogged?

The rotating tool is self-cleaning, since even bigger pieces of mulch or parts of weed come off it really fast. Thus, the machine is clogging free. Moreover, since the Rotor consist of many blades close to each other and is able to cut very fast, it can terminate each and every weed in the row.

How of the do the hoes break?

The forged Swedish blades and the coil-spring element protection allows the machines to work even in hostile conditions, and it is capable of processing areas with a lot of pebbles.

To what extent do weeds return after termination with GYMF?

The rotating blades crush the stems of the weeds, strip the leaves off of them, rip their roots and cover them with soil, so the weeds will not be capable of growing.

What is this adjustable Rotor good for? Isn’t it just an unnecessary function?

This functionality allows you to set working depth in a way that is appropriate for the different soil moisture conditions. This is useful, since it prevents the machine from forming clods from wet layers. Moreover, you can adjust the Rotor according to the amount of weed you need to terminate: for a large number of weeds, you need a steep angle, while a flat angle is suitable for a smaller number of weeds.

Why is it good if I destroy everything between rows? We do not want to work our land bare!

The machine is also capable of controlling cover crops. For this purpose, the working depth is adjusted in a way that the machine does not rip the roots of cover crops, only lays them down and crushes them, thus disrupting their growth.

How can I set the working depth?
Which angle should I use?
How can I change the blades?
What is the maximum working depth?

The small Rotors have a working depth of 8 cm at the most, while the big ones have a maximum working depth of 12 cm.

How do I keep the surface between plants weed free?

We suggest using the finger weeder for this purpose. Original K.U.L.T. Finger weeder. With several sizes and different settings.

Should I buy a finisher for the GYMF?

For the most part, it is not essential for weed control.
