Horsch Tiger disc harrows achieve working depths of between five and 35 centimetres. They can therefore be used both for post-ploughing refinements of seedbeds and for carrying out minimum tillage practices.
There are spring-summer crops that benefit from early sowing, such as corn. This means that at the first available opportunity for sowing, the soil must already be perfectly prepared. This is particularly crucial as the weather conditions between winter and spring significantly limit the time windows available for fieldwork with seed drills. Therefore, surface finishing operations must take place in winter, despite the fact that low temperatures tend to harden the soil. This situation becomes even more challenging for farmers who adopt minimal tillage practices, as they cannot rely on the preliminary soil breaking provided by plowing.
Horsch Tiger: Robust and reliable equipment required
For these reasons, high-strength and reliable equipment is needed—machines capable of preparing seedbeds within reasonable timeframes, even when the soil is particularly compact due to cold or, in extreme cases, rich in stones.
Guaranteed Efficiency
These are complex conditions to which Horsch responds with a line of disc and tine harrows called “Tiger,” divided into two different sub-series: “As” and “Mt,” each designed to meet distinct operational needs. Both series, however, share a combined action of the “TerraGrip” tines and “MulchMix” discs. The tines can exert pressure on the soil up to 550 or 770 kilograms, for the “As” and “Mt” respectively, with maximum working depths of 30 and 28 centimeters. The “MulchMix” discs, on the other hand, feature a design that reduces traction effort by 20% compared to similar market solutions at the same working depth, a benefit that positively impacts fuel consumption.
Horsch Tiger for Post-Plowing as Well
All “Tiger” models can also operate effectively in the presence of cover crops, thanks to a generous ground clearance, with the tine rows spaced 92 centimeters apart and mounted to the harrow frame to maintain a height of 85 centimeters from the ground. The series starts with six “As” models, ideal for medium-light soils, offering working widths ranging from 3 to 7.5 meters. For post-plowing seedbed refinement, they can reach a maximum working depth of 35 centimeters, although they can also operate as shallow as 5 centimeters when minimal tillage is required.
However, not all soils are medium-light. Where the “As” series struggles, the “Mt” series comes into play, featuring an efficient combination of tines and discs. The tines are arranged in two rows, spaced 45 centimeters apart, while the discs, also in two rows, are serrated with a generous diameter of 68 centimeters.
The As and Mt Sub-Series
The discs are distributed along the equipment profile based on the working width, which ranges from 4.5 meters for the smallest model up to 5.7 meters, 6.4 meters, and finally 7.8 meters for the largest model. All equipment complies with the three-meter width limit required by road regulations for public road transport, thanks to a hydraulic folding system that compacts the equipment within the prescribed limits. The two sub-series also differ in weight: the “As” models range from 3,500 to 7,100 kilograms, while the “Mt” models start at 4,200 kilograms, reaching up to 10,400 kilograms for the top model.
A Packer for Every Soil Type
To complete the job, every “Tiger” model is equipped with a roller that comes in various forms, each suited to different soil types and desired outcomes. For refining and compacting the top few centimeters of soil, a pair of “RollPack Packer” rollers with a diameter of 62 centimeters may be useful. Alternatively, for lighter soils, optional single rubber wheels with a one-meter diameter are available, which, when placed side-by-side, form a large pneumatic roller.
Four roller models
The “Optipack Sd” series offers universal packers suitable for most field conditions, available in four models and capable of breaking clods formed by the combined action of the harrow’s tines and discs. Depending on the working width, the weight ranges from 3,400 kilograms for the “Optipack 4 Sd” to about 5,000 kilograms for the “Optipack 8 Sd.” Notably, these models operate with smooth steel discs that can be easily and quickly adjusted as needed, allowing them to work at speeds of up to 15 km/h even on stony soils. Maintenance requirements are minimal, thanks to the excellent self-cleaning properties of the disc elements that make up these tools.
