Packer roller and method of retooling it for different tillage modes

摘要

The present invention relates to a packer roller (10) of an agricultural machine for soil cultivation and / or for the application of seed and / or fertilizer. The packer roller has a plurality of mutually spaced apart and spaced from each other rotatable movable and rolling on the ground packer rings or packer discs. The packer roller provides at least two different machining modes in which the packer rings or packer disks each have differently contoured or profiled outer raceways. A first profiling for a first processing mode of the packer roller provides a first outer running surface of the packer rings or packer disks; a second profiling for a second processing mode of the packer roller provides a second outer tread of the packer rings or packer discs. The packer rings or packer disks formed with second profilings for the second processing mode are each provided with arcuate, one-piece or in each case formed by several segments attachment elements which are positively and / or non-positively connected to the first profile of the packer rollers or packer discs or engage there and their Outer sides each form the annular second tread of the packer rings or packer discs with the second profiling.
