For operation on deeply loosened soils with low carrying ability, AMAZONE offers a second guide wheel set for better load distribution (standard on the 15001-C/optional on the 12001-C). Thanks to the improved load distribution, deeper wheel marks and at the same time harmful compaction are effectively prevented. In addition, a smoother and more precise run of the coulters in the row is achieved, so that the depth maintenance and the placement accuracy are increased.
