The SPE sprayer is designed for the application of plant protection products, plant strengthening agents and similar applications with a stepless, electric drive on the DONKEY XL-T carrier vehicle (carrier vehicle not included). Thanks to its small dimensions (external width 55cm), the device can be used both outdoors and in greenhouses. The equipment of the device and thus the possible uses of the entire device are very flexible. The device represents a significant further development of existing plant protection devices. It is an absolute novelty in this design and equipment. When using conventional cart sprayers with hose lines and spray guns, it is difficult to achieve an even application. The electric movement and the possibility of a constant speed when applying the plant protection products enable extremely precise area-wide application. The spray boom on the sprayer is available in various lengths and can be used horizontally and vertically. The application of plant protection products requires the amount of active ingredient to be applied to an area. All hand-held devices lead to a more or less uneven spray pattern and thus to an uneven distribution of the agent. With the SPE, a close-to-stock and uniform application can be achieved.
