Scaring off insects

The idea of scaring away is known mainly from agriculture. It originated in the course of mechanized grassland mowing, which increased the number of deer killed. By disturbing and scaring away the animals before mowing, the deer can be saved from being mowed to death. This is why the scaring away technique is also used in equipment for extensive grassland maintenance, such as flail or sickle mowers. Robust and all-terrain, a insect scare device should not hinder the work of mowers in dense vegetation and on steep slopes and still do its job.

Requirements for a insect scare device

Robust and all-terrain – a insect scare device should not hinder the work of mowing equipment in dense vegetation and on steep slopes, and still do its job. That’s why the front bar relies on flexible material that deflects and doesn’t break when it comes into contact with obstacles. For larger obstacles, the entire device would fold. For this purpose, the resistance can be adjusted as desired. Folding also offers the advantage that the transport dimensions of the machine does not change. In order to adapt the insect scare device to the growth, it can be variably adjusted in its height and the distance to the device is adjustable as well.

More surviving insects

In cooperation with the Institute of Agricultural Engineering at the University of Hohenheim, various experiments were conducted that confirmed, the benefits of the insect scare device for insect protection. The experiments were conducted using an AS 63 Allmäher as the carrier vehicle. In order to ensure that the results are reliable, comparative runs, with and without the insect scare device, were carried out in several repetitions. The number of insects scattered was determined by means of a catch basket attached to the device. The result clearly shows the benefit of the device. During the experiments, about three times as many insects were flushed out with the insect scare device (compared to the series of experiments without the insect scare device) and thus got out of the danger zone of the mower. Further experiments suggest that insect survival can be further increased by using single blades in combination with mowing at a higher cut.
