The flexibility and efficiency of Pöttinger’s trailed Terria stubble cultivators with three or four rows of tools and working widths of 4m to 6m (Terria 4030, 5030, 6030, 4040, 5040 and 6040 models) has been increased even further with the addition of the company’s Tegosem hopper for sowing seed and applying micro-granules, and a new wheelslip management system.
The developments make it easy to combine tillage and drilling a cover crop, or applying fertiliser, in a single pass, while the Traction Control system means the weight of the cultivator is shifted to the rear axle of the tractor, reducing wheelslip so more power gets to the ground more efficiently. Working efficiently is becoming increasingly important in the field to take full advantage of planting time frames, in addition to meeting deadlines for sowing cover crops after harvest.
The Terria with the flexible Tegosem hopper and its capacity of 500 lit makes this possible. By establishing ground cover rapidly and extensively, unproductive water evaporation is prevented. Likewise, excess nitrogen in the soil is absorbed by the plants and retained on site. Improving and stabilising the soil structure with organisms increases water infiltration while reducing the risk of erosion. By carrying out both tasks in a single pass, the flexible hopper saves time and costs. Reducing the number of passes conserves the soil and any harmful compaction is avoided.
The Tegosem hopper from Pöttinger is equipped with an adaptable metering shaft. This is electrically controlled depending on the driving speed, and it switches off automatically at the headland. Before starting work, the system is optimised by means of a calibration test. A hydraulic fan ensures reliable transport of the material to the distribution plates. To ensure a uniform spread of material close to the ground and to be able to vary the application point, the angle of the distribution plates can be adjusted by twisting the shaft.
The aim is to deposit the seed material in front of or at the rear of the rear roller for optimum germination conditions. A clear and intuitive control terminal is available for operating the flexible Tegosem hopper. This is used to optimise the settings according to the operating conditions. For increased convenience, the flexible Tegosem hopper is equipped with additional features, including a level sensor.
Increased wheelslip not only damages the structure of the soil, it also reduces cost effectiveness by increasing fuel consumption. In order to use the power of the tractor as efficiently as possible, the Terria’s drawbar can be equipped with the Traction Control hydraulic pulling power booster. This system transfers weight from the stubble cultivator to the rear axle of the tractor. The pressure in the drawbar cylinder can be adapted for different working depths, and a weight of up to 1,400kg can be transferred this way. Ultimately, the system reduces operating costs and increases the efficiency of the machine.
Producing a level working pattern is essential for the follow-up tasks and uniform seed emergence. To further improve levelling in locations with light soil types, Terria models with tandem rear rollers can now be equipped with an optional levelling board instead of the concave discs. This creates even and uniform working results and positively influences the tilth.
