Horsch’s Joker Hd disc harrows are designed to tackle the most demanding soil cultivation tasks, including the removal of weeds and their thorough incorporation into the soil. The range includes models with working widths of approximately 4 and 6 meters
The expression “compact and mighty” perfectly captures the philosophy behind Horsch’s Joker HD series, combining impressive performance with relatively compact dimensions. The range consists of two trailed models offering working widths of 4.15 meters and 6.15 meters respectively.
Known as the Joker 4 HD and Joker 6 HD, both machines feature hydraulically folding frames that reduce transport width to the three-meter road limit. Their design meets the demands of modern farming, where high productivity, outstanding work quality, and maximum operational flexibility are essential requirements.
Despite their compact size, the Joker HD harrows are capable of handling the toughest cultivation operations, including the complete removal of volunteer vegetation and its effective incorporation into the soil together with crop residues.
This process takes place without the risk of blockages thanks to the DiscSystem arrangement, which consists of two rows of discs spaced 12.5 cm apart. Each disc is mounted on an individual support arm, with the arms themselves positioned at 40 cm intervals across the frame. This configuration ensures thorough shredding of weeds and crop residues even at forward speeds of up to 18 km/h.
To suit different farming requirements, two types of serrated discs are available, with diameters of either 620 mm or 680 mm. The smaller discs are ideal for cultivation depths of up to 15 cm, while the larger version allows working depths of up to 20 cm.
Both disc options are engineered for maximum durability and benefit from the experience Horsch has gained through its Tiger MT cultivator range, renowned for delivering reliable seedbed preparation even under the most challenging field conditions.
A key factor behind the machines’ precision is the constant disc cutting angle, maintained at 17 degrees relative to the direction of travel. This ensures reliable soil penetration in extremely dry conditions as well as in heavy soils. In addition, the paired arrangement of the discs on their respective supports consistently delivers excellent seedbed preparation, facilitating subsequent planting operations.
The overall design of the Joker HD range also provides exceptional versatility. The machines are equally suited to shallow stubble cultivation, deep incorporation of crop residues, and high-quality seedbed preparation following ploughing.
The working widths offered by the two models are particularly well suited to the needs of many Italian farms, where medium- and small-sized fields remain the norm.
Maximum Versatility
The versatility of the Joker HD range is further enhanced by the wide selection of optional equipment available.
For intensive seedbed preparation, the harrow can be equipped with a hydraulically adjustable Crossbar mounted ahead of the disc rows. Alternatively, the same position can accommodate a six-blade knife roller designed for intensive stubble chopping during either shallow or deep cultivation.
Soil reconsolidation is handled by a comprehensive range of rear rollers, including the 550 mm double RollPack roller, the RingFlex roller, and the OptiRoll roller, the latter being particularly suitable where intensive soil consolidation is required.
