The LION power harrow
for the right seedbed preparation in spring
The farm manager is the ultimate authority in making decisions on what a seedbed is going to look like. It's important that water is treated carefully as a resource so that it is available for the germination stage.
What needs to be done next?
The seed level is prepared depending on the type of crop. This is where the seed is placed to obtain the necessary moisture so that it germinates as quickly and smoothly as possible. With maize the deeply-loosened soil can be raised to around 2 cm within the seed placement depth so that the maize roots can develop easily following germination. The root then rapidly reaches the water-bearing level.
The soil surface structure should be left so that it does not hinder plant growth. A crusty or muddy surface after heavy rain can be detrimental.
Unlike other seedbed preparation methods, LION rotary harrows can often have an influence on the final appearance of the seedbed. First the working depth is adjusted. Then the correct driving speed and the position of the levelling plate. This provides additional pulverisation of earth clods as it is dragged across the surface of the soil close to the active tine area. However, it is also possible to overdo this be pulverising the whole seedbed. This would then cause a muddy surface during rain. In addition to the working depth and driving speed, another important factor for seedbed preparation with LION power harrows is the range of speeds of rotation of the tines: this can be adjusted by changing the PTO speed of the tractor or by changing gear wheels directly on the harrow.
On the other hand, the method of re-compaction depends very much on the type of soil and the moisture content of the ground. The important factor is that the seed is provided with the optimum conditions for uniform and stress-free germination. Too fine a structure on the surface can cause mud and crust, which prevent the exchange of gases. A rough, clod-strewn surface, however, makes it difficult to achieve the desired level of cover for the seed.
With Pöttinger power rotary harrows a wide selection of trailed rollers is available, ranging from standard cage drum rollers to packer rollers and rollers with strip-wise compaction; cutting packer rollers and crumbling packer rollers.
