Creates an immediate and effective mechanical growth stop in potatoes.

The Crown Crusher has been tested for 3 seasons with good results. The function is to crush the sprout in the top of the potato plant and subsequently cover it with soil. Under the right conditions, growth is stopped immediately and effectively with only one pass – without prior haulm topping. The subsequent covering with soil protects the tubers and also reduces the risk of infection from potato blight.

In 2023, an extra tool for the Crown Crusher will be launched – the stem lifting and separating function. It means that the Crown Crusher can be used in the vast majority of potato types, even where the tops are lying down and tangled. The stem lifting and separating function lifts the lying stems and cuts the rows up and free from each other. This minimizes infection from sap mist and fallen material. The crushed tops can be placed on top, between the rows, or spread out.

In certain situations, it may be necessary to supplement with chemicals to achieve a complete growth stop. This can, for example, be in situations with early maturation of the potatoes, where the top of the plant is still green and alive at the time of growth stop.

Compared to other machines for mechanical desiccation, the Crown Crusher has a significantly greater capacity – up to 75%. Today, it is one of the best mechanical alternatives to the use of Reglone.

The Crown Crusher is developed, produced, and serviced in Denmark. It is supplied with an external hydraulic station. If the Crown Crusher is to be solely dependent on the tractor, it requires a power of at least 200 L of oil per minute.
