Yes, but on the condition that its primary purpose fits the cultivation technology. The ActiVAgro weeder harrow works well in many types of crops and on grasslands, and a rotary hoe provides additional flexibility in row crops as well. However, if the main goal is post-harvest work and stimulating volunteers, it is better to choose a Rolmako machine designed specifically for this task (e.g., the SpeedCutter disc harrow or the SpringExpert mulch harrow).

The working width is best selected based on the area, weather windows, and the tractor's capabilities. A larger machine provides higher efficiency, but it must be paired with adequate power and stable operation in the field. The machines in this category work shallowly, so they typically have a low power demand, but ultimately, it is worth looking at the specific configuration.

A Rolmako mulch harrow or seedbed cultivator (e.g., ComboTill) is a better choice when the goal is not typical weeding of a growing crop, but fast post-harvest work, stimulating volunteers and weeds to emerge, and their destruction in a subsequent pass. This is a good solution if you are interested in indirect weed control and tidying up the field from the very first pass.

In a weeder, the working intensity is primarily set by the working angle and tine pressure – greater pressure and a more aggressive setting help with heavier weed infestation or harder soil surfaces. With the MATRIX rotary hoe, the key factor is mainly the driving speed. The farm machine works at a depth of up to approx. 40 mm, and the faster it goes, the shallower it works and the better it protects the crops.

The speed should be adapted to the field conditions and the desired effect. Driving too slowly can reduce the machine's effectiveness, while driving too aggressively can increase the risk of crop damage. For example, for the MATRIX rotary hoe manufactured by Rolmako, effective operation requires a working speed in the range of 10–25 km/h.

With mechanical weeding, what counts is very shallow work, sufficient to disturb the soil surface and remove young weeds – usually in the 2–3 cm range. The depth must be adapted to the crop stage, weed infestation, and soil conditions.

The operation is too aggressive when, in addition to weeds, it also begins to visibly damage the crops. In practice, this is evident when plants are pulled out, heavily covered with soil, or the plantation looks too disturbed after a pass. This is a signal that you need to reduce the pressure or limit the working speed.

Yes, in many cases, this is possible. The ActiVAgro weeder can operate right after sowing, before the crop enters the emergence phase. This solution allows for controlling weeds very early, before they have a chance to develop strongly.

Yes, dry conditions after the operation usually enhance the effectiveness of mechanical weeding because the uprooted weeds remain on the soil surface and dry out more easily.

It is worth avoiding this if the goal is effective mechanical weed control. The best effect is achieved by uprooting the weeds and leaving them on the surface to dry out, so excessive moisture can weaken this effect.

On grassland, the Rolmako weeder is primarily used for raking out thatch and levelling molehills. At the same time, it helps to control weeds, break up the surface crust, and aerate the soil, which improves plant growth conditions.

Yes, but indirectly. With very shallow work, a mulch harrow creates conditions in the topsoil that encourage the rapid germination of weed seeds and volunteers. This allows them to be destroyed in a subsequent pass, ideally at the cotyledon stage.

This most often happens when the working intensity is too high. In such cases, it is worth reducing the pressure of the working elements or the operating speed.

This most often happens when the operation is carried out too late, and the weeds are already too large and more firmly rooted. The best results are achieved when the weeds are at the cotyledon or first true leaf stage, and the topsoil crumbles into small lumps after harrowing. If conditions are poorer or the weeds are too developed, the effectiveness drops significantly.

The problem in such situations is most often insufficient working intensity or the machine's poor adaptation to the field surface. The most important factors are uniform section pressure, adjustment of the tine working angle, and good ground contouring, as these determine the effective raking of turf, destruction of molehills, and soil aeration.
