Modern construction

Uniform pressure on the discs along the entire length of the machine is achieved by advancing the axle and implementing a design with two foldable side frames. This design minimizes the need for multiple hydraulic cylinders, thereby reducing the risk of pressure loss on the side arms. Even with a working width of up to 12 meters, the disc harrow remains extremely compact during transport, not exceeding a transport width of 3 meters. Additionally, the machine's height remains just under 4 meters, even with double U-RING rollers. This compactness during transport is primarily due to a mechanism for folding the frame towards the drawbar. Despite the large working width, this design allows the disc harrow to be easily moved between fields or on public roads, enhancing its practicality and efficiency in agricultural work.







Crossboard drag

The harrow 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.





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.

The optimized angle of attack is identical for both rows of discs, ensuring the machine follows the tractor precisely. The quality of the steel and the extensive experience gained through many years of production by the Italian company OFAS guarantee a top-quality product that has been approved worldwide. Discs with an aggressive tine are primarily used for working in fields with substantial straw. The disc tines facilitate easier machine penetration in challenging dry conditions. Smooth and fine-toothed discs are designed for shallower pre-sowing cultivation. The ALFA disc delivers excellent results on stubble after corn harvested for grain.





Hydraulic adjustment of working depth

Hydraulic depth adjustment ensures optimum comfort of use and significantly facilitates activities related to setting this work parameter. The hydraulic adjustment of working depth, which is easy and operator-friendly, is conducted using spacer clips on cylinders. This option is justified when frequent changes in the working depth of the machine's elements are required.





Bearing units of the roller

By incorporating maintenance-free bearings into the tillage rollers, we minimize the required machine maintenance time. The ductile cast iron housing is four times more durable than its grey cast iron counterpart. The combination of top and internal sealing offers superior protection for agricultural use. Rolmako prioritizes the smallest machine elements in every project, significantly impacting maintenance time and reducing the costs and duration of agricultural equipment inspections.
