The ActiVAgro weeder is a versatile unit used not only for standard crops but also for the maintenance of grasslands. It serves as an excellent alternative to chemical weed control. The primary function of the harrow is to minimize weed presence and break up surface crust. The ActiVAgro is also effective for harrowing freshly sown areas before the plants enter the emergence phase. Weeds can be removed immediately after growth or even earlier, during the germination phase, where they dry out and die when left on the soil surface. The weeder features standard hydraulic frame folding, which adapts to the terrain during operation, ensuring even pressure distribution. The angle of the harrow tines can be adjusted mechanically or hydraulically from the tractor cabin using actuators. This design ensures consistent performance across each working section of the harrow.
The ideal alternative to chemical weed control
A single device applicable to various crop types
The primary function of the weeder is to rake turf and eliminate molehills in meadows. This tool is highly effective in eradicating weeds in cereals and legumes. It is applicable to various crops, including rapeseed, other cereals, vegetables, corn, sugar beets, potatoes, soybeans, peas, pumpkins, grasslands, and meadows. With extended working widths, the weeder excels in adapting to ground conditions and ensuring smooth operation. The machine is designed to provide specific benefits, such as reduced chemical usage, improved conditions for plant growth, and weed protection. Additionally, it aerates the soil, which is vital for optimal plant growth. The substantial working width enhances efficiency. The device can also be equipped with an APV catch crop seeder with either a pneumatic or hydraulic blower.
Designed for durability and comfort
Available working widths range from 6.00 m to 12.00 m. None of the versions exceed 3 m transport width due to the hydraulic scissor arm folding system, allowing maximum reduction of transport width and height. The device is mounted on a 3-point suspension system. Each working section is 1.5 m wide and consists of 48 tines arranged in 6 rows. The weeder is constructed on a solid frame, with each working part mounted individually on a swing arm. This design effectively mirrors the terrain. The machine enables the destruction of weeds at an early development stage through specially profiled spring working elements.

Cultivation tools
Cultivation tines
All tasks are performed by 7 mm (optionally 8 mm) spring tines arranged in 6 rows. The spacing between the tines is optimized through extensive testing in various soil conditions and different crops. This ensures consistent cultivation intensity across the entire working width and between rows. When using the ActiVAgro harrow, achieving uniform weeding was prioritized. An optimal vibration effect is achieved through the triple coiling of the spring. Lateral vibration of the tines combined with driving speed results in comprehensive processing. The extended tip of the harrow tine prolongs its service life. The optimized bending angle of the working element ensures effective weed elimination and crust breaking during harrowing. These tines have also proven effective in different crops, as the longer tines adapt better to uneven soil.
The primary properties
Mechanical weeding
With the advent of herbicides, it was anticipated that mechanical methods of weed control would decline in popularity. However, this did not occur, as some farmers consciously and voluntarily chose to forgo chemicals in their fields, opting instead for proven mechanical methods. Interest in weeders is not limited to organic farmers. The withdrawal of certain herbicides has also increased interest among conventional farmers. Currently, an increasing number of growers, including traditional ones, are turning to mechanical weeding for their crops. Consequently, Rolmako has introduced ActiVAgro to the market—a weeder in a new version. The decline of active substances, issues with the availability of plant protection products, and rising costs have led agricultural producers to increasingly adopt alternative, mechanical methods of weed control. The ActiVAgro weeder is a user-friendly and durable tool that meets the modern farmer's requirements for efficient weeding of both cereals and grass fields.

The standard mechanical adjustment of the working spring angle can be replaced with a convenient hydraulic setting. The ActiVAgro weeder's working sections have been divided into 1.5 m modules, each equipped with 48 springs. Each swing frame with springs is set separately, and for larger working widths, it is useful to hydraulically adjust the angle of inclination of the spring fingers. Both mechanical and hydraulic adjustments of working elements allow for the correct setting of the tines mounted on the swinging frames.
