Cultivation tools
Cultivator tines
All variants of the unit's tines facilitate various cultivation operations efficiently, ensuring optimal results and consistently low operating costs. The SS tine, sized 45 mm x 12 mm with a narrow 300x52x7 mm coulter, is typical for pre-sowing cultivation, similar to the Belotta SW tine 70 mm x 12 mm equipped with a 300x52 x7 mm coultre. The unit's purpose shifts when a 180 mm wide goosefoot is installed. The ST tine, sized 90x13 mm with a straight 300x60x10 mm coulter, is used for challenging crops, employing a 280 mm wide goosefoot for heavy stubble work. The machine can be ordered in a mixed configuration, where tines end with a narrow coulter in one row and a goosefoot in another. Both the SW and ST tines are available with an additional spring reinforcement, designed for extremely difficult conditions.
Looseners of tractor traces
When working with soils sensitive to compaction and reduced working depth, the use of tractor wheel track eradicators is advisable. Positioned directly behind the tractor, these eradicators lift, loosen, and level soil compacted by the wheels. The position of the wheel track eradicators can be adjusted both horizontally and vertically. The spring-loaded working element ensures consistent release force. Effective loosening of the tractor wheel tracks eliminates uneven plant emergence post-sowing.
Front leveling drag
The front drag is designed to pre-level and break up larger clods. Due to the leveled surface, all tines operate at the same depth. This is an effective levelling tool. Depth adjustment is achieved by inserting the pin into the appropriate hole without tools. The front drag is mechanically adjusted and features overload protection through spring amortisation. The precisely leveled soil surface enables even compaction and loosening of the seedbed. The front drag used in cultivators has a simple, solid, and reliable design.
Crossboard drag
The drag is constructed from hardened springs and bent working tips. Positioned ahead of the disc section, it breaks up clods and levels the field, creating an optimal surface for sowing. The harrow is effective on stony fields as it does not bring stones to the surface. For challenging conditions, an optional stabilizing beam can be mounted to connect the working elements into a unified system for enhanced leveling. When a hard crust forms on the field surface, an aggressive skid with DoubleKnife tines is recommended.
Spring comb beam
The manufacturer optionally installs a beam with a spring comb behind the rear tillage roller, ensuring the straw is evenly spread across the field's surface, thereby preventing areas of high straw accumulation that hinder proper cultivation. Uniform straw distribution is crucial, as it ensures consistent development conditions for the next crop across the entire field. The spring comb is an effective tool that enhances cultivation, offering optimal starting conditions for sown plants.
APV aftercrop seeder
We equip our cultivation machines with catch crop seeders in cooperation with specialists from APV, who offer a wide range of catch crop and fertilizer seeders. The entire range of products and available accessories can be found on the manufacturer's website (https://www.apv-polska.com). By utilizing APV catch crop seeders on Rolmako cultivation machines, unnecessary travel is reduced. APV devices ensure the precise spreading of catch crops and subsowing, even in the smallest doses.
Tillage rollers
Kneading, compacting the soil, crushing clods, and leveling the field surface are the final stages of cultivation, performed by the rear roller following the working tools of the cultivation machines. The selection of the appropriate cultivation roller significantly impacts the entire work process and the functionality of the cultivation machine. At Rolmako, we offer a variety of cultivation rollers that differ in shape, material, external diameter, weight, and, most importantly, cultivation purpose. The choice of roller depends on the soil type and the desired cultivation outcome. Rolmako provides expert advisory services to ensure proper adjustment of the cultivation machine to the working conditions.
