The flexible 500 l TEGOSEM hopper combines high-output tillage with the application of cover crops or micro-granules in a single pass. By carrying out both tasks in a single pass, the flexible hopper saves time and costs, reduces soil compaction and produces precision working results.
Two different sizes of metering shaft are provided as standard to ensure precision distribution of the seed material or micro-granules. The driving speed controls either the fine or coarse metering shaft, even when low application rates are required. Changing between metering shafts is quick and easy without the need for tools. Before starting work, the system is optimised using a calibration test.
The material is transported pneumatically through eight spiral hoses from the metering system on the drawbar to the distribution plates. Due to the distance that the material needs to be conveyed, the fan on the TERRIA is driven hydraulically. This provides a continuous flow over the entire length of the hose for reliable transport without blocking the hose.
Surface application and distribution is carried out by baffle plates close to the ground. This guarantees full surface application regardless of the wind conditions. The distributor plates are adjusted by changing the shaft angle to vary the distribution range.
The shaft with the baffle plates is positioned in front of the rear roller. As a result, the seed is immediately pressed into the soil. Soil contact is established and capillary action for successful seed emergence starts straight away.
The different functions and settings of the flexible TEGOSEM hopper are operated using its dedicated control unit. The settings for precision metering are entered and the calibration test is started at the push of a button.
Sensor signals needed during operation, such as the ground speed and the position of the lower linkage, can be input from the tractor. If the tractor cannot provide these signals, add-on sensors are available. For increased convenience, the flexible TEGOSEM hopper is equipped with additional features, including a level sensor.
