Excellent fruit size and quality are attained by using the mechanical thinning with the Darwin.
Thinning is mandatory in order to reach high fruit quality and high yields. This is very important in particular with new apple cultivars with high flowering intensity and high fruit-charge. The regulation of apple fruit is one of the most important crop factors that contribute to ensure fruit quality.
The idea of mechanical thinning out arose 1990 from the desire for a thinning method, which is labour-saving, chemistry-free and as weather independent as possible.
In the course of several years of work and experience, Hermann Gessler, fruit grower from the Bodensee area (Lake of Constance), developed a patented system of a mechanical thinning machine, which became generally accepted and is often used.
The machine is attached to the front hydraulic system of the tractor or to the coupling mouth by means of an expander, if the tractor does not possess front hydraulic system. The hydraulic adjustment of the spindle inclination allows the adaptation to the tree form or to the ground.
The spindle together with the tractor drives closely along the tree rows and cuts thereby buds, flower clusters, or individual blooms depending upon the point of assignment.
